Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation: The accompanying Unaudited Consolidated Financial Statements of Peoples Bancorp Inc. and its subsidiaries ("Peoples" refers to Peoples Bancorp Inc. and its consolidated subsidiaries collectively, except where the context indicates the reference relates solely to Peoples Bancorp Inc.) have been prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) for interim financial information and the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not contain all of the information and footnotes required by US GAAP for annual financial statements and should be read in conjunction with Peoples’ Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (“Peoples' 2017 Form 10-K”). The accounting and reporting policies followed in the presentation of the accompanying Unaudited Consolidated Financial Statements are consistent with those described in Note 1 of the Notes to the Consolidated Financial Statements included in Peoples’ 2017 Form 10-K, as updated by the information contained in this Form 10-Q. Management has evaluated all significant events and transactions that occurred after March 31, 2018 for potential recognition or disclosure in these consolidated financial statements. In the opinion of management, these consolidated financial statements reflect all adjustments necessary to present fairly such information for the periods and at the dates indicated. Such adjustments are normal and recurring in nature. Intercompany accounts and transactions have been eliminated. The Consolidated Balance Sheet at December 31, 2017 , contained herein, has been derived from the audited Consolidated Balance Sheet included in Peoples’ 2017 Form 10-K. The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Results of operations for interim periods are not necessarily indicative of the results to be expected for the full year, due in part to seasonal variations and unusual or infrequently occurring items. New Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies that are adopted by Peoples as of the required effective dates. Accounting Standards Update ("ASU") 2018-05 - Income Taxes (Topic 740): Amendment to clarify situations where a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting under ASC 740 for certain income tax effects of the Tax Cuts and Jobs Act for the reporting period. As of December 31, 2017, Peoples partially completed the accounting for the tax effects of enactment of the Tax Cuts and Jobs Act; however, in certain cases, Peoples made reasonable estimates of the effects of a reduced federal corporate income tax rate on its existing deferred tax balances. In other cases, Peoples has not been able to make a reasonable estimate and continued to account for those items based on its existing accounting under ASC 740, and the provisions of the tax laws that were in effect immediately prior to enactment of the Tax Cuts and Jobs Act. In all cases, Peoples will continue to make and refine its calculations during the one-year re-measurement period as additional analysis is completed. In addition, these estimates may be affected as Peoples gains a more thorough understanding of the new tax reform legislation. ASU 2018-04 - Investments - Debt Securities (Topic 320) and Regulated Operations (Topic 980): The amendment in this ASU adds, amends and supersedes various paragraphs that contain SEC guidance in ASC 320, Investments-Debt Securities and ASC 980, Regulated Operations. The amendments in this ASU are effective when a registrant adopts ASU 2016-01, which for Peoples, was January 1, 2018. This amendment is not expected to have an impact on Peoples' consolidated financial statements. ASU 2018-02 - Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. Peoples early adopted ASU 2018-02, reclassifying income tax effects of the Tax Cuts and Jobs Act of $0.9 million from accumulated other comprehensive loss to retained earnings as of December 31, 2017. ASU 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships, and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components, and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2016-13 - Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This accounting guidance replaces the current “incurred loss” model for recognizing credit losses with an “expected loss” model, referred to as the Current Expected Credit Loss (“CECL”) model. Under the CECL model, Peoples will be required to present certain financial assets carried at amortized cost, such as loans held-for-investment and held-to-maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the “incurred loss” model required under current US GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, Peoples expects that the adoption of the CECL model will materially affect how the allowance for loan losses is determined and could require significant increases to the allowance for loan losses. Moreover, the CECL model may create more volatility in the level of Peoples' allowance for loan losses. If required to materially increase the level of allowance for loan losses for any reason, such increase could adversely affect Peoples' business, financial condition and results of operations. The new CECL standard will become effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020 for Peoples). Peoples is currently evaluating the impact that the CECL model will have on Peoples' financial statements and expects to recognize a one-time cumulative-effect adjustment to the allowance for loan loss provision as of the beginning of the first reporting period in which the new standard is effective, consistent with regulatory expectations set forth in interagency guidance issued at the end of 2016. Peoples has not yet determined the magnitude of any such one-time cumulative adjustment or of the overall impact of the new standard on Peoples' financial condition or results of operations. ASU 2016-02 - Leases (Topic 842): This ASU was issued to improve the financial reporting of leasing activities and provide a faithful representation of leasing transactions and improve understanding and comparability of a lessee's financial statements. Under the new accounting guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. This ASU will require both finance and operating leases to be recognized on the balance sheet. This ASU will affect all companies and organizations that lease real estate. The FASB issued an update in January 2018 (ASU 2018-01) providing an optional transition practical expedient to not evaluate under Topic 842 land easements that exist or expired before the entity's adoption of Topic 842. This ASU will become effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended
	Mar. 31, 2018
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Assets and Liabilities Fair value represents the amount expected to be received to sell an asset or paid to transfer a liability in its principal or most advantageous market in an orderly transaction between market participants at the measurement date. In accordance with fair value accounting guidance, Peoples measures, records, and reports various types of assets and liabilities at fair value on either a recurring or non-recurring basis in the Consolidated Financial Statements. Those assets and liabilities are presented below in the sections entitled “Assets and Liabilities Required to be Measured and Reported at Fair Value on a Recurring Basis” and “Assets and Liabilities Required to be Measured and Reported at Fair Value on a Non-Recurring Basis.” Depending on the nature of the asset or liability, Peoples uses various valuation methodologies and assumptions to estimate fair value. The measurement of fair value under US GAAP uses a hierarchy intended to maximize the use of observable inputs and minimize the use of unobservable inputs. This hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows: Level 1: Quoted prices in active exchange markets for identical assets or liabilities; also includes certain U.S. Treasury and other U.S. government and agency securities actively traded in over-the-counter markets. Level 2: Observable inputs other than Level 1 including quoted prices for similar assets or liabilities, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data; also includes derivative contracts whose value is determined using a pricing model with observable market inputs or can be derived principally from, or corroborated by, observable market data. This category generally includes certain U.S. government and agency securities, corporate debt securities, derivative instruments, and residential mortgage loans held for sale. Level 3: Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs for single dealer nonbinding quotes not corroborated by observable market data. This category generally includes certain private equity investments, retained interests from securitizations, and certain collateralized debt obligations. Assets and liabilities are assigned to a level within the fair value hierarchy based on the lowest level of significant input used to measure fair value. Assets and liabilities may change levels within the fair value hierarchy due to market conditions or other circumstances. Those transfers are recognized on the date of the event that prompted the transfer. There were no transfers of assets or liabilities required to be measured at fair value on a recurring basis between levels of the fair value hierarchy during the periods presented. Assets and Liabilities Required to be Measured and Reported at Fair Value on a Recurring Basis The following table provides the fair value for assets and liabilities required to be measured and reported at fair value on a recurring basis in the Consolidated Balance Sheets by level in the fair value hierarchy. Recurring Fair Value Measurements at Reporting Date March 31, 2018 December 31, 2017 (Dollars in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets: Securities available-for-sale: Obligations of: States and political subdivisions $ — $ 97,205 $ — $ — $ 101,569 $ — Residential mortgage-backed securities — 681,746 — — 673,664 — Commercial mortgage-backed securities — 6,864 — — 6,976 — Bank-issued trust preferred securities — 5,095 — — 5,129 — Equity securities (a) — — — 7,694 155 Total available-for-sale securities — 790,910 — 7,694 787,493 — Securities held-to-maturity: Obligations of: States and political subdivisions — 4,300 — — 4,417 — Residential mortgage-backed securities — 30,978 — — 32,227 — Commercial mortgage-backed securities — 4,162 — — 4,569 — Total held-to-maturity securities — 39,440 — — 41,213 — Equity securities (a) 7,311 160 — — — — Derivative assets (b) — 6,633 — — 4,594 — Liabilities: Derivative liabilities (c) $ — $ 3,870 $ — $ — $ 3,241 $ — (a) As of January 1, 2018, Peoples adopted ASU 2016-01, resulting in the reclassification of equity securities from available-for-sale investment securities to other investment securities. As of December 31, 2017, equity securities had a net unrealized gain of $6.5 million . (b) Included in other assets on the Consolidated Balance Sheets. For additional information, see Note 9 of the Notes to the Unaudited Consolidated Financial Statements. (c) Included in other liabilities on the Consolidated Balance Sheets. For additional information, see Note 9 of the Notes to the Unaudited Consolidated Financial Statements. Securities Available-for-Sale and Held-to-Maturity: The fair values used by Peoples are obtained from an independent pricing service and represent either quoted market prices for the identical securities (Level 1) or fair values determined by pricing models using a market approach that considers observable market data, such as interest rate volatility, LIBOR yield curves, credit spreads and prices from market makers and live trading systems (Level 2). Management reviews the valuation methodology and quality controls utilized by the pricing services in management's overall assessment of the reasonableness of the fair values provided, and challenges prices when management believes a material discrepancy in pricing exists. Equity Securities: The fair value of Peoples' equity securities are obtained from q uoted prices in active exchange markets for identical assets or liabilities (Level 1) or quoted prices in less active markets (Level 2). Derivative Assets/Liabilities : Derivative assets/liabilities are recognized in the Consolidated Balance Sheets at their fair value within other assets/liabilities. The fair value for derivative instruments is determined based on market prices, broker-dealer quotations on similar products, or other related input parameters (Level 2). Assets and Liabilities Required to be Measured and Reported at Fair Value on a Non-Recurring Basis The following table provides the fair value for each class of assets and liabilities required to be measured and reported at fair value on a non-recurring basis in the Consolidated Balance Sheets by level in the fair value hierarchy. Non-Recurring Fair Value Measurements at Reporting Date March 31, 2018 December 31, 2017 (Dollars in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Impaired loans $ — $ — $ 20,386 $ — $ — $ 20,602 Loans held for sale — — 3,581 — — 2,510 Other real estate owned (OREO) — — 99 — — 208 Impaired Loans: Impaired loans are measured and reported at fair value when the amounts to be received are less than the carrying value of the loans. One of the allowable methods for determining the amount of impairment is estimating fair value using the fair value of the collateral for collateral-dependent loans. Management’s determination of the fair value for these loans uses a market approach representing the estimated net proceeds to be received from the sale of the collateral based on observable market prices or the market value provided by independent, licensed or certified appraisers (Level 3), less estimated selling costs. At March 31, 2018 , impaired loans had an aggregate outstanding principal balance of $25.2 million . For the three months ended March 31, 2018 , Peoples recognized $20,000 of losses on impaired loans, through the allowance for loan losses. Loans Held for Sale: Loans originated and intended to be sold in the secondary market, generally one-to-four family residential loans, are carried at the lower of cost or estimated fair value determined on an aggregate basis (Level 3). Other Real Estate Owned: Other real estate owned ("OREO"), included in other assets on the Consolidated Balance Sheets, is comprised primarily of commercial and residential real estate properties acquired by Peoples in satisfaction of a loan. OREO obtained in satisfaction of a loan is recorded at the lower of cost or estimated fair value, less estimated costs to sell the property (Level 3). Financial Instruments Not Required to be Measured or Reported at Fair Value The following table provides the carrying amount for each class of assets and liabilities and the fair value for certain financial instruments that are not required to be measured or reported at fair value in the Consolidated Balance Sheets.

(b) Included in other intangible assets on the Consolidated Balance Sheets. Servicing rights are carried at the lower of cost or market. For certain financial assets and liabilities, carrying value approximates fair value due to the nature of the financial instrument. These instruments include cash and cash equivalents, demand and other non-maturity deposits, and overnight borrowings. Peoples used the following methods and assumptions in estimating the fair value of the following financial instruments: Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, balances due from other banks, interest-bearing deposits in other banks, federal funds sold and other short-term investments with original maturities of ninety days or less (Level 1). Other Investment Securities: Certain restricted equity securities that do not have readily determinable fair values and for which Peoples does not exercise significant influence, are carried at cost. These cost method securities are reported as other investment securities on the Consolidated Balance Sheets and consist primarily of shares of the Federal Home Loan Bank of Cincinnati (the “FHLB”) and the Federal Reserve Bank of Cleveland (the "FRB") (Level 2). Loans: The fair value of portfolio loans assumes sale of the notes to a third-party financial investor. Accordingly, this value is not necessarily the value to Peoples if the notes were held to maturity. Peoples considered interest rate, credit and market factors in estimating the fair value of loans (Level 3). In the current whole loan market, financial investors are generally requiring a higher rate of return than the return inherent in loans if held to maturity given the lack of market liquidity. This divergence accounts for the majority of the difference in carrying amount over fair value. Bank Owned Life Insurance: Peoples’s bank owned life insurance policies are recorded at their cash surrender value (Level 3). Peoples recognizes tax-exempt income from the periodic increases in the cash surrender value of these policies and from death benefits. Bank Premises and Equipment: Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the related assets owned. Major improvements to leased facilities are capitalized and included in bank premises at cost less accumulated depreciation, which is calculated on the straight-line method over the lesser of the remaining term of the leased facility or the estimated economic life of the improvement (Level 3). Servicing Rights ("SRs") : SRs are recorded at fair value at the time of the sale of the loans to the third-party investor. Peoples follows the amortization method for the subsequent measurement of each class of separately recognized servicing assets and liabilities. Under the amortization method, Peoples amortizes the value of servicing assets or liabilities in proportion to, and over the period of, estimated net servicing income or net servicing loss, and assesses servicing assets or liabilities for impairment or increased obligation based on the fair value at each reporting date. The fair value of the SRs is determined by using a discounted cash flow model, which estimates the present value of the future net cash flows of the servicing portfolio based on various factors, such as servicing costs, expected prepayment speeds and discount rates (Level 3). Deposits: The fair value of fixed maturity certificates of deposit is estimated using a discounted cash flow calculation based on current rates offered for deposits of similar remaining maturities (Level 2). Short-term Borrowings: The fair value of short-term borrowings is estimated using discounted cash flow analysis based on rates currently available to Peoples for borrowings with similar terms (Level 2). Long-term Borrowings: The fair value of long-term borrowings is estimated using a discounted cash flow analysis based on rates currently available to Peoples for borrowings with similar terms (Level 2). Certain financial assets and financial liabilities that are not required to be measured or reported at fair value can be subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). These financial assets and liabilities include the following: customer relationships, deposit base, banking center networks, and other information required to compute Peoples’ aggregate fair value that are not included in the above information. Accordingly, the above fair values are not intended to represent the aggregate fair value of Peoples.

Peoples' investment in equity securities was comprised largely of common stocks issued by various unrelated bank holding companies at both March 31, 2018 and December 31, 2017 . At December 31, 2017, there were no equity securities of a single issuer that exceeded 10% of stockholders' equity. The gross gains and gross losses realized by Peoples from sales of available-for-sale securities for the periods ended March 31 were as follows: Three Months Ended March 31, (Dollars in thousands) 2018 2017 Gross gains realized $ 2 $ 340 Gross losses realized 1 — Net gain (loss) realized $ 1 $ 340 The cost of investment securities sold, and any resulting gain or loss, was based on the specific identification method and recognized as of the trade date.

Management systematically evaluates available-for-sale investment securities for other-than-temporary declines in fair value on a quarterly basis. At March 31, 2018 , management concluded no individual securities were other-than-temporarily impaired since Peoples did not have the intent to sell, nor was it more likely than not that Peoples would be required to sell, any of the securities with an unrealized loss prior to recovery. Further, the unrealized losses at both March 31, 2018 and December 31, 2017 were largely attributable to changes in market interest rates and spreads since the securities were purchased. At March 31, 2018 , approximately 99% of the mortgage-backed securities with a market value that had been at an unrealized loss position for twelve months or more were issued by U.S. government sponsored agencies. The remaining 1% , or four positions, consisted of privately issued mortgage-backed securities with all of the underlying mortgages originated prior to 2004. Two of the four positions had a fair value of less than 90% of their book value, with an aggregate book and fair value of $0.5 million and $0.3 million , respectively. Management analyzed the underlying credit quality of these securities and concluded the unrealized losses were primarily attributable to the floating rate nature of these investments and the low number of loans remaining in these securities. Furthermore, the unrealized losses with respect to the three bank-issued trust preferred securities that had been in an unrealized loss position for twelve months or more at March 31, 2018 were primarily attributable to the floating-rate nature of those investments, the current interest rate environment and spreads within that sector. The table below presents the amortized cost, fair value and total weighted-average yield of available-for-sale securities by contractual maturity at March 31, 2018 . The weighted-average yields are based on the amortized cost. In some cases, the issuers may have the right to call or prepay obligations without call or prepayment penalties prior to the contractual maturity date.

Receivables [Abstract]
Loans	Loans Peoples' loan portfolio consists of various types of loans originated primarily as a result of lending opportunities within Peoples' primary market areas of northeastern, central, southwestern and southeastern Ohio, west central West Virginia, and northeastern Kentucky. Acquired loans consist of loans purchased in 2012 or thereafter. Loans that were acquired and subsequently re-underwritten, are reported as originated upon execution of such credit actions (for example, renewals and increases in lines of credit). The major classifications of loan balances (in each case, net of deferred fees and costs) excluding loans held for sale, were as follows: (Dollars in thousands) March 31, December 31, 2017 Originated loans: Commercial real estate, construction $ 99,757 $ 107,118 Commercial real estate, other 627,932 595,447 Commercial real estate 727,689 702,565 Commercial and industrial 455,243 438,051 Residential real estate 302,890 304,523 Home equity lines of credit 87,722 88,902 Consumer, indirect 347,607 340,390 Consumer, direct 67,386 67,010 Consumer 414,993 407,400 Deposit account overdrafts 543 849 Total originated loans $ 1,989,080 $ 1,942,290 Acquired loans: Commercial real estate, construction $ 8,054 $ 8,319 Commercial real estate, other 156,115 165,120 Commercial real estate 164,169 173,439 Commercial and industrial 33,815 34,493 Residential real estate 194,063 184,864 Home equity lines of credit 20,008 20,575 Consumer, indirect 253 329 Consumer, direct 940 1,147 Consumer 1,193 1,476 Total acquired loans $ 413,248 $ 414,847 Loans, net of deferred fees and costs $ 2,402,328 $ 2,357,137 Peoples has acquired various loans through business combinations for which there was, at acquisition, evidence of deterioration of credit quality since origination, and for which it was probable that all contractually required payments would not be collected. The carrying amounts of these purchased credit impaired loans included in the loan balances above are summarized as follows: (Dollars in thousands) March 31, December 31, Commercial real estate, other $ 7,794 $ 8,117 Commercial and industrial 718 767 Residential real estate 19,156 19,532 Consumer 27 33 Total outstanding balance $ 27,695 $ 28,449 Net carrying amount $ 18,864 $ 19,564 Changes in the accretable yield for purchased credit impaired loans for the three months ended March 31, 2018 were as follows: For the three moths ended (Dollars in thousands) March 31, March 31, Balance, December 31, 2017 $ 6,704 $ 7,132 Accretion (412 ) (461 ) Balance, March 31, 2018 $ 6,292 $ 6,671 Peoples completes annual re-estimations of cash flows on acquired purchased credit impaired loans in August of each year. At the end of each quarter, Peoples evaluates factors to determine if a material change has occurred in acquired loans accounted for and if a re-estimation is needed. Factors evaluated to determine if a re-estimation is needed include changes in: risk ratings, maturity dates, charge-offs, payoffs, nonaccrual status and loans that have become past due. Cash flows expected to be collected on purchased credit impaired loans are estimated by incorporating several key assumptions, similar to the initial estimate of fair value. These key assumptions include probability of default and the amount of actual prepayments after the acquisition date. Prepayments affect the estimated life of the loans and could change the amount of interest income and possibly the principal expected to be collected. In re-forecasting future estimated cash flows, credit loss expectations are adjusted as necessary. Peoples pledges certain loans secured by 1-4 family and multifamily residential mortgages under a blanket collateral agreement to secure borrowings from the FHLB. The amount of such pledged loans totaled $486.5 million and $487.2 million at March 31, 2018 and December 31, 2017 , respectively. Peoples also pledges commercial loans to secure borrowings with the FRB. The outstanding balances of these loans totaled $71.5 million and $74.0 million at March 31, 2018 and December 31, 2017 , respectively. Nonaccrual and Past Due Loans A loan is considered past due if any required principal and interest payments have not been received as of the date such payments were required to be made under the terms of the loan agreement. A loan may be placed on nonaccrual status regardless of whether or not such loan is considered past due. The recorded investments in loans on nonaccrual status and loans delinquent for 90 days or more and accruing were as follows: Nonaccrual Loans Loans 90+ Days Past Due and Accruing (Dollars in thousands) March 31, December 31, March 31, December 31, Originated loans: Commercial real estate, construction $ 732 $ 754 $ — $ — Commercial real estate, other 6,673 6,877 — — Commercial real estate 7,405 7,631 — — Commercial and industrial 1,598 739 — — Residential real estate 3,666 3,546 298 548 Home equity lines of credit 507 550 29 50 Consumer, indirect 306 256 — — Consumer, direct 17 39 — 16 Consumer 323 295 — 16 Total originated loans $ 13,499 $ 12,761 $ 327 $ 614 Acquired loans: Commercial real estate, other $ 269 $ 192 $ 71 $ 215 Commercial and industrial 141 259 — 45 Residential real estate 2,062 2,168 632 730 Home equity lines of credit 230 312 — 22 Consumer, direct 1 — — — Total acquired loans $ 2,703 $ 2,931 $ 703 $ 1,012 Total loans $ 16,202 $ 15,692 $ 1,030 $ 1,626 The following table presents the aging of the recorded investment in past due loans: Loans Past Due Current Loans Total Loans (Dollars in thousands) 30 - 59 days 60 - 89 days 90 + Days Total March 31, 2018 Originated loans: Commercial real estate, construction $ — $ — $ 732 $ 732 $ 99,025 $ 99,757 Commercial real estate, other 596 — 6,512 7,108 620,824 627,932 Commercial real estate 596 — 7,244 7,840 719,849 727,689 Commercial and industrial 1,352 1,180 1,570 4,102 451,141 455,243 Residential real estate 4,220 1,107 1,778 7,105 295,785 302,890 Home equity lines of credit 111 122 337 570 87,152 87,722 Consumer, indirect 1,510 176 152 1,838 345,769 347,607 Consumer, direct 204 24 11 239 67,147 67,386 Consumer 1,714 200 163 2,077 412,916 414,993 Deposit account overdrafts — — — — 543 543 Total originated loans $ 7,993 $ 2,609 $ 11,092 $ 21,694 $ 1,967,386 $ 1,989,080 Acquired loans: Commercial real estate, construction $ 33 $ — $ — $ 33 $ 8,021 $ 8,054 Commercial real estate, other 490 — 264 754 155,361 156,115 Commercial real estate 523 — 264 787 163,382 164,169 Commercial and industrial — — 105 105 33,710 33,815 Residential real estate 2,499 782 1,982 5,263 188,800 194,063 Home equity lines of credit 59 — 182 241 19,767 20,008 Consumer, indirect 4 — — 4 249 253 Consumer, direct 16 2 — 18 922 940 Consumer 20 2 — 22 1,171 1,193 Total acquired loans $ 3,101 $ 784 $ 2,533 $ 6,418 $ 406,830 $ 413,248 Total loans $ 11,094 $ 3,393 $ 13,625 $ 28,112 $ 2,374,216 $ 2,402,328 Loans Past Due Current Loans Total Loans (Dollars in thousands) 30 - 59 days 60 - 89 days 90 + Days Total December 31, 2017 Originated loans: Commercial real estate, construction $ — $ — $ — $ — $ 107,118 $ 107,118 Commercial real estate, other 990 — 6,492 7,482 587,965 595,447 Commercial real estate 990 — 6,492 7,482 695,083 702,565 Commercial and industrial 1,423 92 706 2,221 435,830 438,051 Residential real estate 4,562 1,234 2,408 8,204 296,319 304,523 Home equity lines of credit 502 80 395 977 87,925 88,902 Consumer, indirect 2,153 648 105 2,906 337,484 340,390 Consumer, direct 417 46 48 511 66,499 67,010 Consumer 2,570 694 153 3,417 403,983 407,400 Deposit account overdrafts — — — — 849 849 Total originated loans $ 10,047 $ 2,100 $ 10,154 $ 22,301 $ 1,919,989 $ 1,942,290 Acquired loans: Commercial real estate, construction $ — $ — $ — $ — $ 8,319 $ 8,319 Commercial real estate, other 775 948 312 2,035 163,085 165,120 Commercial real estate 775 948 312 2,035 171,404 173,439 Commercial and industrial — 1 171 172 34,321 34,493 Residential real estate 4,656 1,391 1,910 7,957 176,907 184,864 Home equity lines of credit 126 — 301 427 20,148 20,575 Consumer, indirect 3 — — 3 326 329 Consumer, direct 10 11 — 21 1,126 1,147 Consumer 13 11 — 24 1,452 1,476 Total acquired loans $ 5,570 $ 2,351 $ 2,694 $ 10,615 $ 404,232 $ 414,847 Total loans $ 15,617 $ 4,451 $ 12,848 $ 32,916 $ 2,324,221 $ 2,357,137 During the first three months of 2018, Peoples' delinquency trends improved compared to the balances at December 31, 2017, as total loans past due declined in both the originated and acquired loan portfolios. Credit Quality Indicators As discussed in Note 1 of the Notes to the Consolidated Financial Statements included in Peoples' 2017 Form 10-K, Peoples categorizes the majority of its loans into risk categories based upon an established risk grading matrix using a scale of 1 to 8. A description of the general characteristics of the risk grades used by Peoples is as follows: “Pass” (grades 1 through 4): Loans in this risk category involve borrowers of acceptable-to-strong credit quality and risk who have the apparent ability to satisfy their loan obligations. Loans in this risk grade would possess sufficient mitigating factors, such as adequate collateral or strong guarantors possessing the capacity to repay the loan if required, for any weakness that may exist. “Special Mention” (grade 5): Loans in this risk grade are the equivalent of the regulatory definition of “Other Assets Especially Mentioned.” Loans in this risk category possess some credit deficiency or potential weakness, which requires a high level of management attention. Potential weaknesses include declining trends in operating earnings and cash flows and/or reliance on a secondary source of repayment. If left uncorrected, these potential weaknesses may result in noticeable deterioration of the repayment prospects for the loan or in Peoples' credit position. “Substandard” (grade 6): Loans in this risk grade are inadequately protected by the borrower's current financial condition and payment capability or the collateral pledged, if any. Loans so classified have one or more well-defined weaknesses that jeopardize the orderly repayment of the loan. They are characterized by the distinct possibility that Peoples will sustain some loss if the deficiencies are not corrected. “Doubtful” (grade 7): Loans in this risk grade have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or orderly repayment in full, on the basis of current existing facts, conditions and values, highly questionable and improbable. Possibility of loss is extremely high, but because of certain important and reasonably specific factors that may work to the advantage and strengthening of the exposure, classification of the loan as an estimated loss is deferred until its more exact status may be determined. “Loss” (grade 8): Loans in this risk grade are considered to be non-collectible and of such little value that their continuance as bankable assets is not warranted. This does not mean a loan has absolutely no recovery value, but rather it is neither practical nor desirable to defer writing off the loan, even though partial recovery may be obtained in the future. Charge-offs against the allowance for loan losses are taken in the period in which the loan becomes uncollectible. Consequently, Peoples typically does not maintain a recorded investment in loans within this category. Consumer loans and other smaller-balance loans are evaluated and categorized as “substandard,” “doubtful,” or “loss” based upon the regulatory definition of these classes and consistent with regulatory requirements. All other loans not evaluated individually, nor meeting the regulatory conditions to be categorized as described above, would be considered as being “not rated.” The following table summarizes the risk category of loans within Peoples' loan portfolio based upon the most recent analysis performed: Pass Rated (Grades 1 - 4) Special Mention (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) March 31, 2018 Originated loans: Commercial real estate, construction $ 92,383 $ 6,190 $ 732 $ — $ 452 $ 99,757 Commercial real estate, other 596,903 14,058 16,971 — — 627,932 Commercial real estate 689,286 20,248 17,703 — 452 727,689 Commercial and industrial 404,591 46,477 4,175 — — 455,243 Residential real estate 17,037 579 11,270 131 273,873 302,890 Home equity lines of credit 454 — — — 87,268 87,722 Consumer, indirect 51 6 — — 347,550 347,607 Consumer, direct 37 — — — 67,349 67,386 Consumer 88 6 — — 414,899 414,993 Deposit account overdrafts — — — — 543 543 Total originated loans $ 1,111,456 $ 67,310 $ 33,148 $ 131 $ 777,035 $ 1,989,080 Acquired loans: Commercial real estate, construction $ 8,003 $ — $ 51 $ — $ — $ 8,054 Commercial real estate, other 144,647 3,440 7,918 110 — 156,115 Commercial real estate 152,650 3,440 7,969 110 — 164,169 Commercial and industrial 31,351 185 2,279 — — 33,815 Residential real estate 11,633 647 1,024 — 180,759 194,063 Home equity lines of credit 44 — — — 19,964 20,008 Consumer, indirect 8 — — — 245 253 Consumer, direct 32 — — — 908 940 Consumer 40 — — — 1,153 1,193 Total acquired loans $ 195,718 $ 4,272 $ 11,272 $ 110 $ 201,876 $ 413,248 Total loans $ 1,307,174 $ 71,582 $ 44,420 $ 241 $ 978,911 $ 2,402,328 Pass Rated (Grades 1 - 4) Special Mention (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) December 31, 2017 Originated loans: Commercial real estate, construction $ 100,409 $ 5,502 $ 754 $ — $ 453 $ 107,118 Commercial real estate, other 561,320 17,189 16,938 — — 595,447 Commercial real estate 661,729 22,691 17,692 — 453 702,565 Commercial and industrial 420,477 13,062 4,512 — — 438,051 Residential real estate 17,896 1,000 11,371 216 274,040 304,523 Home equity lines of credit 454 — — — 88,448 88,902 Consumer, indirect 55 8 — — 340,327 340,390 Consumer, direct 33 — — — 66,977 67,010 Consumer 88 8 — — 407,304 407,400 Deposit account overdrafts — — — — 849 849 Total originated loans $ 1,100,644 $ 36,761 $ 33,575 $ 216 $ 771,094 $ 1,942,290 Acquired loans: Commercial real estate, construction $ 8,267 $ — $ 52 $ — $ — $ 8,319 Commercial real estate, other 149,486 6,527 9,107 — — 165,120 Commercial real estate 157,753 6,527 9,159 — — 173,439 Commercial and industrial 32,011 157 2,325 — — 34,493 Residential real estate 12,543 593 1,105 — 170,623 184,864 Home equity lines of credit 124 — — — 20,451 20,575 Consumer, indirect 12 — — — 317 329 Consumer, direct 35 — — — 1,112 1,147 Consumer 47 — — — 1,429 1,476 Total acquired loans $ 202,478 $ 7,277 $ 12,589 $ — $ 192,503 $ 414,847 Total loans $ 1,303,122 $ 44,038 $ 46,164 $ 216 $ 963,597 $ 2,357,137 In the first three months of 2018, Peoples' classified loans, which are loans categorized as substandard or doubtful, declined compared to the balances at December 31, 2017 mostly due to loan payoffs.

In assessing whether or not a borrower is experiencing financial difficulties, Peoples considers information currently available regarding the financial condition of the borrower. This information includes, but is not limited to, whether (i) the borrower is currently in payment default on any of the borrower's debt; (ii) a payment default is probable in the foreseeable future without the modification; (iii) the borrower has declared or is in the process of declaring bankruptcy; and (iv) the borrower's projected cash flow is insufficient to satisfy contractual payments due under the original terms of the loan without a modification. Peoples considers all aspects of the modification to loan terms to determine whether or not a concession has been granted to the borrower. Key factors considered by Peoples include the borrower's ability to access funds at a market rate for debt with similar risk characteristics, the significance of the modification relative to the unpaid principal balance or collateral value of the debt, and the significance of a delay in the timing of payments relative to the original contractual terms of the loan. The most common concessions granted by Peoples generally include one or more modifications to the terms of the loan, such as (i) a reduction in the interest rate for the remaining life of the loan, (ii) an extension of the maturity date at an interest rate lower than the current market rate for new loans with similar risk, (iii) a temporary period of interest-only payments, and (iv) a reduction in the contractual payment amount for either a short period or the remaining term of the loan.

Decreases in expected cash flows of acquired purchased credit impaired loans are recognized as an impairment, with the amount of the expected loss included in management's evaluation of the appropriateness of the allowance for loan losses. The methods utilized to estimate the required allowance for loan losses for nonimpaired acquired loans are similar to those utilized for originated loans; however, Peoples records a provision for loan losses only when the computed allowance exceeds the remaining fair value adjustment.

During the first three months of 2018, no additional borrowings were entered into and one long-term FHLB non-amortizing advance in the amount of $20.0 million was reclassified to short-term borrowings as the maturity became less than one year. As of March 31, 2018 , Peoples' FHLB putable and callable option-based advances had one remaining putable or callable option. The FHLB has the option, at its sole discretion, to terminate the advance after the initial fixed rate period of three months, requiring full repayment of the advance by Peoples, prior to the stated maturity. If the advance is terminated prior to maturity, the FHLB will offer Peoples replacement funding at the then-prevailing rate on an advance product then offered by the FHLB, subject to normal FHLB credit and collateral requirements. Peoples is required to make quarterly interest payments. The amortizing, fixed-rate FHLB advances have a fixed rate for the term of each advance, with maturities ranging from two to thirteen years . These advances require monthly principal and interest payments, with some having a constant prepayment rate requiring an additional principal payment annually. These advances are not eligible for optional prepayment prior to maturity. Peoples has entered into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for Peoples making fixed payments. As of March 31, 2018 , Peoples had seven interest rate swaps with a notional value of $ 60.0 million associated with Peoples' cash outflows for various FHLB advances. Two of the seven swaps became effective in January 2018. Of the five remaining swaps two will become effective in April 2018, one in July of 2018 and two in October 2018. Theses dates roughly coincide with the maturity of existing FHLB advances. Additional information regarding Peoples' interest rate swaps can be found in Note 14 of the Notes to the Unaudited Consolidated Financial Statements included in Peoples' 2017 Form 10-K..

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans Peoples sponsors a noncontributory defined benefit pension plan that covers substantially all employees hired before January 1, 2010. The plan provides retirement benefits based on an employee’s years of service and compensation. For employees hired before January 1, 2003, the amount of postretirement benefit is based on the employee’s average monthly compensation over the highest five consecutive years out of the employee’s last ten years with Peoples while an eligible employee. For employees hired on or after January 1, 2003, the amount of postretirement benefit is based on 2% of the employee’s annual compensation during the years 2003 through 2009, plus accrued interest. Effective January 1, 2010, the pension plan was closed to new entrants. Effective March 1, 2011, the accrual of pension plan benefits for all participants was frozen. Peoples recognized this freeze as a curtailment as of December 31, 2010 and March 1, 2011, under the terms of the pension plan. Peoples also provides post-retirement health and life insurance benefits to former employees and directors. Only those individuals who retired before January 27, 2012 were eligible for life insurance benefits. As of January 1, 2011, all retirees who desire to participate in Peoples medical plan do so by electing COBRA, which provides up to 18 months of coverage; retirees over the age of 65 also have the option to pay to participate in a group Medicare supplemental plan. Peoples’ policy is to fund the cost of the health benefits as they arise. The following tables detail the components of the net periodic cost for the plans: Pension Benefits Three Months Ended March 31, (Dollars in thousands) 2018 2017 Interest cost $ 105 $ 113 Expected return on plan assets (147 ) (138 ) Amortization of net loss 28 25 Net periodic cost $ (14 ) $ — Postretirement Benefits Three Months Ended March 31, (Dollars in thousands) 2018 2017 Interest cost $ 1 $ 1 Amortization of net gain (2 ) (2 ) Net periodic cost $ (1 ) $ (1 ) There were no settlement charges recorded in the three months ended March 31, 2018 or March 31, 2017 under the noncontributory defined benefit pension plan.

Financial Instruments with Off-Balance Sheet Risk [Abstract]
Financial Instruments Disclosure [Text Block]	Financial Instruments with Off-Balance Sheet Risk Derivatives and Hedging Activities - Risk Management Objective of Using Derivatives Peoples is exposed to certain risks arising from both its business operations and economic conditions. Peoples principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. Peoples manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, Peoples enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known or expected cash amounts, the value of which are determined by interest rates. Peoples’ derivative financial instruments are used to manage differences in the amount, timing, and duration of Peoples' known or expected cash receipts and its known or expected cash payments principally related to certain variable rate borrowings. Peoples also has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in Peoples' assets or liabilities. Peoples manages a matched book with respect to customer-related derivative financial instruments in order to minimize its net risk exposure resulting from such transactions. Fair Values of Derivative Instruments on the Balance Sheet Peoples' fair value of the derivative financial instruments was $ 6.6 million in an asset position and $ 3.9 million in a liability position at March 31, 2018 , and there was $ 4.6 million in an asset position and $ 3.2 million in a liability position at December 31, 2017 . The amounts are recorded in other assets, and accrued expenses and other liabilities on the consolidated balance sheet at the periods indicated. Cash Flow Hedges of Interest Rate Risk Peoples' objectives in using interest rate derivatives are to add stability to interest income and expense, and to manage its exposure to interest rate movements. To accomplish these objectives, Peoples has entered into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for Peoples making fixed payments. As of March 31, 2018 , Peoples had seven interest rate swaps with a notional value of $ 60.0 million associated with Peoples' cash outflows for various FHLB advances. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of each derivative is initially reported in accumulated other comprehensive income ("AOCI") (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. Peoples assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transaction. T he reset dates and the payment dates on the 90-day advances used to fund the swaps are matched to the reset dates and payment dates on the receipt of the 3-month LIBOR floating portion of the swaps to ensure effectiveness of the cashflow hedge. Effectiveness is measured by ensuring that reset dates and payment dates are matched. Peoples entered into the seven interest rate swap contracts, described above, whereby Peoples will pay a fixed rate of interest for up to ten years while receiving a floating rate component of interest equal to the three-month LIBOR rate. The received floating rate component is intended to offset the rate on the rolling three-month FHLB advances. Amounts reported in AOCI related to derivatives will be reclassified to interest income or expense as interest payments are made or received on Peoples' variable-rate assets or liabilities. During the three months ended March 31, 2018 , and March 31, 2017 , Peoples had no reclassifications to interest expense. During the next twelve months, Peoples estimates that no interest expense amount will be reclassified. The amount of accumulated other comprehensive pre-tax income for Peoples' cash flow hedges was $ 2.8 million at March 31, 2018 . There were no pre-tax net losses recorded for the three months ended March 31, 2018 . Additionally, Peoples had no reclassifications to earnings in the three months ended March 31, 2018 or March 31, 2017 . Non-Designated Hedges Peoples maintains an interest rate protection program for commercial loan customers, which was established in 2010. Under this program, Peoples provides its customer with a fixed-rate loan while creating a variable-rate asset for Peoples by the customer entering into an interest rate swap with Peoples on terms that match the loan. Peoples offsets its risk exposure by entering into an offsetting interest rate swap with an unaffiliated institution. These interest rate swaps do not qualify as designated hedges; therefore, each swap is accounted for as a standalone derivative. Peoples had interest rate swaps associated with commercial loans with a notional value of $ 373.1 million and fair value of $ 3.9 million of equally offsetting assets and liabilities at March 31, 2018 , and a notional value of $ 363.3 million and fair value of $ 3.0 million of equally offsetting assets and liabilities at December 31, 2017 . These interest rate swaps did not have a material impact on Peoples' results of operation or financial condition.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Under the Peoples Bancorp Inc. Second Amended and Restated 2006 Equity Plan (the "2006 Equity Plan"), Peoples may grant, among other awards, nonqualified stock options, incentive stock options, restricted stock awards, stock appreciation rights ("SARs") and unrestricted share awards to employees and non-employee directors. The total number of common shares available under the 2006 Equity Plan is 1,081,260 . The maximum number of common shares that can be issued for incentive stock options is 800,000 common shares. Prior to 2007, Peoples granted nonqualified and incentive stock options to employees and nonqualified stock options to non-employee directors under the 2006 Equity Plan and predecessor plans. Since 2009, Peoples has granted restricted common shares to employees and restricted common shares to non-employee directors subject to the terms and conditions prescribed by the 2006 Equity Plan. In 2018, the Board of Directors granted unrestricted common shares to non-employee directors and to all full-time and part-time employees who did not already participate in the equity plans. In general, common shares issued in connection with stock-based awards are issued from treasury shares to the extent available. If no treasury shares are available, common shares are issued from authorized but unissued common shares. Stock Appreciation Rights SARs granted to employees have an exercise price equal to the fair market value of Peoples’ common shares on the date of grant and will be settled using common shares of Peoples. Additionally, the SARs granted to employees vested three years after the respective grant dates and expired ten years from the respective date of grant. The most recent grant of SARs occurred in 2008 and expired on February 20, 2018. The following table summarizes the changes to Peoples' SARs for the three months ended March 31, 2018 : Number of Common Shares Subject to SARs Weighted- Average Exercise Price Weighted-Average Remaining Contractual Life Aggregate Intrinsic Value Outstanding at January 1 314 $ 23.77 Exercised 314 23.77 Outstanding at March 31 — $ — 0.0 years $ — Exercisable at March 31 — $ — 0.0 years $ — Restricted Common Shares Under the 2006 Equity Plan, Peoples may award restricted common shares to officers, key employees and non-employee directors. Restrictions on restricted common shares awarded to non-employee directors expired after six months , for awards granted through 2017. Beginning in 2018, common shares awarded to non-employee directors vest immediately upon grant with no restrictions. Restrictions on restricted common shares awarded to employees expire after periods ranging from one to three years . In the first three months of 2018 , Peoples granted an aggregate of 84,876 restricted common shares subject to performance-based vesting to officers and key employees with restrictions that will lapse three years after the grant date provided that in order for the restricted common shares to vest in full, Peoples must have reported positive net income and maintained a well capitalized status by regulatory standards for each of the three fiscal years preceding the vesting date. During the first three months of 2018 , Peoples granted, to certain key employees, an aggregate of 2,000 restricted common shares subject to time-based vesting with restrictions that will lapse three years after the grant date. The following table summarizes the changes to Peoples’ restricted common shares for the three months ended March 31, 2018 : Time-Based Vesting Performance-Based Vesting Number of Common Shares Weighted-Average Grant Date Fair Value Number of Common Shares Weighted-Average Grant Date Fair Value Outstanding at January 1 33,082 $ 22.85 176,218 $ 25.50 Awarded 2,000 35.32 84,876 35.43 Released — — 82,861 23.63 Forfeited — — 170 33.66 Outstanding at March 31 35,082 $ 23.56 178,063 $ 31.09 For the three months ended March 31, 2018 , the total intrinsic value for restricted common shares released was $ 2.9 million compared to $0.7 million for the three months ended March 31, 2017 . Stock-Based Compensation Peoples recognizes stock-based compensation expense, which is included as a component of Peoples' salaries and employee benefit costs, based on the estimated fair value of the awards on the grant date. The following table summarizes the amount of stock-based compensation expense and related tax benefit recognized for each period: Three Months Ended March 31, (Dollars in thousands) 2018 2017 Total stock-based compensation expense $ 1,028 $ 568 Recognized tax benefit (216 ) (199 ) Net expense recognized $ 812 $ 369 Total unrecognized stock-based compensation expense related to unvested awards was $ 3.1 million at March 31, 2018 , which will be recognized over a weighted-average period of 2.2 years . On January 31, 2018, Peoples granted, to non-employee directors, an aggregate of 3,600 unrestricted common shares, which resulted in an additional $128,000 of stock-based compensation expense being recognized. On February 14, 2018, the Board of Directors granted an aggregate of 11,112 unrestricted common shares to all full-time and part-time employees who did not already participate in the equity plans, which resulted in an additional $388,000 of stock-based compensation expense being recognized. Performance Unit Award Agreement Under the 2006 Equity Plan, Peoples may award performance unit awards to officers, key employees and non-employee directors. On July 26, 2017, Peoples granted a total of seven performance unit awards to officers with a maximum aggregate dollar amount of $1.3 million represented by the performance units subject to such awards, with each performance unit representing $1.00. The performance unit awards granted are for the performance period beginning January 1, 2018 and ending on December 31, 2019, and will be subject to two performance goals. Twenty-five percent of the performance units subject to each award will vest if, but only if, the related target performance goal is achieved. The remaining 75% of the performance units subject to each award will vest based on the relative performance (measured by percentile ranking) with respect to the related maximum performance goal. If for the performance period, the target level of achievement for the first performance goal and/or the maximum level of achievement for the second performance goal is not reached, the dollar amount represented by the performance units associated with each performance goal will be adjusted to reflect the level of performance achieved. After the vesting date, the participant will receive that number of common shares of Peoples equal to (i) the aggregate number of participant's performance units (and dollar value of such performance units) that vested based on the performance achieved under both performance goals (ii) divided by the fair market value of a common share of Peoples on the date of such vesting and rounded down to the nearest whole common share.

Revenue Recognition and Deferred Revenue [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue As of January 1, 2018, Peoples adopted ASU 2014-09 - Revenue from Contracts with Customers (Topic 606), and all subsequent updates that modified ASC 606. Peoples has elected to adopt this new accounting guidance using the modified retrospective approach. The modified retrospective approach uses a cumulative-effect adjustment to retained earnings to reflect uncompleted contracts in the initial application of the guidance. As of January 1, 2018, Peoples recorded a cumulative-effect adjustment for uncompleted contracts, which resulted in a reduction to retained earnings and an increase in accrued expenses and other liabilities of $3.1 million , which is net of federal income taxes. The impact during the first quarter of 2018 was an increase in insurance income and a decrease in retained earnings of $0.4 million as a result of applying ASC 606. Prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for those respective periods. Peoples recognizes revenues as they are earned based on contractual terms, or as services are provided and collectability is reasonably assured. Estimates of variable consideration are included in revenue to the extent that it is probable that a significant reversal of cumulative revenue will not occur, once the uncertainty is resolved. Peoples recognizes revenue from contracts with customers under the following revenue streams: Insurance Income: Insurance income generally consists of commissions and fees from the sale of insurance policies, third-party administration services and performance-based commissions from insurance companies. Peoples recognizes commission income from the sale of insurance policies when it acts as an agent between the insurance carrier and policyholder, arranging for the insurance carrier to provide policies to policyholders, and acts on behalf of the insurance carrier by providing customer service to the policyholder during the policy period. Commission income is recognized over time, using the output method of time elapsed, which corresponds with the underlying insurance policy period, for which Peoples is obligated to perform under contract with the insurance carrier. Commission income is variable, as it is comprised of a certain percentage of the underlying policy premium. Peoples estimates the variable consideration based upon the "most likely amount" method, and does not expect or anticipate a significant reversal of revenue in future periods, based upon historical experience. Payment is due from the insurance carrier for commission income once the insurance policy has been sold. Peoples has elected to apply a practical expedient related to capitalizable costs, which are the commissions paid to insurance producers, and will expense these commissions paid to insurance producers as incurred, as these costs are related to the commission income and would have been amortized within one year or less if they had been capitalized, the same period over which the commission income was earned. Fees related to third-party administration services performed are recognized over time, in the period in which services have been provided, and are recognized monthly in the month the services were performed. Performance-based commissions from insurance companies are recognized at a point in time, when received, and no contingencies remain. Trust and Investment Income: Trust and investment income consists of revenue from fiduciary and brokerage activities, which includes fees for services such as asset management, record keeping, retirement services and estate management, and investment commissions and fees related to the sale of investments. Trust and investment income is recognized over time which reflects the duration of the contract period for which services have been provided. Trust and investment income is variable as it is based on the value of assets under administration and management, and specific transactions. Peoples estimates the variable consideration based upon the most likely amount method, and does not expect or anticipate a significant reversal of revenue in future periods. Payment is due from the customer when billed, which is typically a monthly or quarterly billing for services rendered in the most recent period, for which the performance obligation has been satisfied. Peoples has elected to apply a practical expedient of right to invoice when recognizing trust and investment income, as Peoples has fulfilled the performance obligation, the customer has consumed the service, and Peoples has a right to the related income. Peoples has also elected to apply a practical expedient related to capitalizable costs, which are the commissions paid to financial advisors, and will expense these commissions paid to financial advisors as incurred, as these costs are related to the trust and investment income and would have been amortized within one year or less if they had been capitalized, the same period over which the income was earned. Electronic Banking Income: Electronic banking income consists of two revenue streams related to interchange income and promotional and usage income. Peoples recognizes interchange income over time, on a monthly basis, and is based on transactional volume of debit card activity completed by its customers during the month in which income is recognized. Peoples is obligated to certain debit card activity being performed by its customers over a certain period of time. Interchange income is variable as it is based on the transaction volume of debit card activity completed by Peoples' customers. Peoples estimates the variable consideration based upon the most likely amount method, and does not expect or anticipate a significant reversal of revenue in future periods. Payment is due from the vendor within one month of the completed customer debit card activity. Peoples has elected to apply a practical expedient of right to invoice when recognizing interchange income, as Peoples has fulfilled the required performance obligations, the vendor has consumed the service, and Peoples has a right to the related income. Peoples also recognizes promotional and usage income over time, on a monthly basis, and is related to branding of debit cards and promotion or use of certain services provided by third-party vendors. Peoples is obligated to brand its debit cards in a certain manner, and promote and use services provided by third-party vendors. Promotional and usage income is variable as it is based on certain metrics achieved for promotion and usage of services provided by the third-party vendors. Peoples estimates the variable consideration based upon the most likely amount method, and does not expect or anticipate a significant reversal of revenue in future periods. Payment is due from the third-party vendor within 45 days of the monthly fulfillment of Peoples' performance obligation. Peoples has elected to apply a practical expedient of right to invoice when recognizing promotional and usage income, as Peoples has fulfilled the required performance obligations, the vendor has consumed the service, and Peoples has a right to the related income. Deposit Account Service Charges: Deposit account service charges consist of two revenue streams related to ongoing maintenance fees for deposit accounts and certain transactional-based fees. Ongoing maintenance fees are recognized on a monthly basis, with the monthly period beginning on the day of the month on which the account was opened. Ongoing maintenance fee income is variable as these fees can be reduced if a customer meets certain qualifying metrics. Peoples estimates the variable consideration based upon the most likely amount method, and does not expect or anticipate a significant reversal of revenue in future periods. For accounts that are assessed maintenance fees through the account analysis process, payment is due from the customer within one month of the monthly period in which the account was open. For all other accounts, monthly maintenance fees are assessed to the account on the last day of the monthly period. Peoples has elected to apply a practical expedient of right to invoice when recognizing ongoing maintenance fees for deposit accounts, as Peoples has fulfilled the required performance obligations, the customer has consumed the service, and Peoples has a right to the related income. Transactional-based deposit account fees are recognized at a point in time, which is at the completion of the relevant transaction. Peoples is obligated to perform certain transactions as requested by its consumer and business deposit account customers, which are outside of the normal maintenance requirements. Transactional-based deposit account fee income is variable as these fees are directly related to a service request from the customer. Peoples estimates the variable consideration based upon the most likely amount method, and does not expect or anticipate a significant reversal of revenue in future periods. Payment is due from the customer at the time of completion of the requested transaction. Commercial Loan Swap Fees: Commercial loan swap fees consist of income related to transactions in which Peoples acts as an agent between a third-party vendor and certain Peoples commercial loan customers for which an interest rate swap occurs. Commercial loan swap fees are recognized at a point in time, when the transaction has been completed, and there is no recourse or further performance obligation required of Peoples. Commercial loan swap fee income is variable as these fees are a certain percentage of the total swap fee collected on a completed transaction. Peoples estimates the variable consideration based upon the most likely amount method, and does not expect or anticipate a significant reversal of revenue in future periods. Payment is due from the customer at the time of completion of the requested transaction. Other Non-Interest Income: Other non-interest income includes certain revenues that are transactional-based, such as wire transfer fees, money order fees and other ancillary fees or services. These transactional-based fees are recognized as income at a point in time, at the completion of the relevant transaction. Transactional-based other non-interest income is variable as these fees are directly related to a service request from the customer. Peoples estimates the variable consideration based upon the most likely amount method, and does not expect or anticipate a significant reversal of revenue in future periods. Payment is due from the customer at the time of completion of the requested transaction.

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies that are adopted by Peoples as of the required effective dates. Accounting Standards Update ("ASU") 2018-05 - Income Taxes (Topic 740): Amendment to clarify situations where a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting under ASC 740 for certain income tax effects of the Tax Cuts and Jobs Act for the reporting period. As of December 31, 2017, Peoples partially completed the accounting for the tax effects of enactment of the Tax Cuts and Jobs Act; however, in certain cases, Peoples made reasonable estimates of the effects of a reduced federal corporate income tax rate on its existing deferred tax balances. In other cases, Peoples has not been able to make a reasonable estimate and continued to account for those items based on its existing accounting under ASC 740, and the provisions of the tax laws that were in effect immediately prior to enactment of the Tax Cuts and Jobs Act. In all cases, Peoples will continue to make and refine its calculations during the one-year re-measurement period as additional analysis is completed. In addition, these estimates may be affected as Peoples gains a more thorough understanding of the new tax reform legislation. ASU 2018-04 - Investments - Debt Securities (Topic 320) and Regulated Operations (Topic 980): The amendment in this ASU adds, amends and supersedes various paragraphs that contain SEC guidance in ASC 320, Investments-Debt Securities and ASC 980, Regulated Operations. The amendments in this ASU are effective when a registrant adopts ASU 2016-01, which for Peoples, was January 1, 2018. This amendment is not expected to have an impact on Peoples' consolidated financial statements. ASU 2018-02 - Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. Peoples early adopted ASU 2018-02, reclassifying income tax effects of the Tax Cuts and Jobs Act of $0.9 million from accumulated other comprehensive loss to retained earnings as of December 31, 2017. ASU 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships, and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components, and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements. ASU 2016-13 - Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This accounting guidance replaces the current “incurred loss” model for recognizing credit losses with an “expected loss” model, referred to as the Current Expected Credit Loss (“CECL”) model. Under the CECL model, Peoples will be required to present certain financial assets carried at amortized cost, such as loans held-for-investment and held-to-maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the “incurred loss” model required under current US GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, Peoples expects that the adoption of the CECL model will materially affect how the allowance for loan losses is determined and could require significant increases to the allowance for loan losses. Moreover, the CECL model may create more volatility in the level of Peoples' allowance for loan losses. If required to materially increase the level of allowance for loan losses for any reason, such increase could adversely affect Peoples' business, financial condition and results of operations. The new CECL standard will become effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020 for Peoples). Peoples is currently evaluating the impact that the CECL model will have on Peoples' financial statements and expects to recognize a one-time cumulative-effect adjustment to the allowance for loan loss provision as of the beginning of the first reporting period in which the new standard is effective, consistent with regulatory expectations set forth in interagency guidance issued at the end of 2016. Peoples has not yet determined the magnitude of any such one-time cumulative adjustment or of the overall impact of the new standard on Peoples' financial condition or results of operations. ASU 2016-02 - Leases (Topic 842): This ASU was issued to improve the financial reporting of leasing activities and provide a faithful representation of leasing transactions and improve understanding and comparability of a lessee's financial statements. Under the new accounting guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. This ASU will require both finance and operating leases to be recognized on the balance sheet. This ASU will affect all companies and organizations that lease real estate. The FASB issued an update in January 2018 (ASU 2018-01) providing an optional transition practical expedient to not evaluate under Topic 842 land easements that exist or expired before the entity's adoption of Topic 842. This ASU will become effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019 for Peoples). Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' consolidated financial statements.

Loans	Loans Peoples' loan portfolio consists of various types of loans originated primarily as a result of lending opportunities within Peoples' primary market areas of northeastern, central, southwestern and southeastern Ohio, west central West Virginia, and northeastern Kentucky. Acquired loans consist of loans purchased in 2012 or thereafter. Loans that were acquired and subsequently re-underwritten, are reported as originated upon execution of such credit actions (for example, renewals and increases in lines of credit). The major classifications of loan balances (in each case, net of deferred fees and costs) excluding loans held for sale, were as follows: (Dollars in thousands) March 31, December 31, 2017 Originated loans: Commercial real estate, construction $ 99,757 $ 107,118 Commercial real estate, other 627,932 595,447 Commercial real estate 727,689 702,565 Commercial and industrial 455,243 438,051 Residential real estate 302,890 304,523 Home equity lines of credit 87,722 88,902 Consumer, indirect 347,607 340,390 Consumer, direct 67,386 67,010 Consumer 414,993 407,400 Deposit account overdrafts 543 849 Total originated loans $ 1,989,080 $ 1,942,290 Acquired loans: Commercial real estate, construction $ 8,054 $ 8,319 Commercial real estate, other 156,115 165,120 Commercial real estate 164,169 173,439 Commercial and industrial 33,815 34,493 Residential real estate 194,063 184,864 Home equity lines of credit 20,008 20,575 Consumer, indirect 253 329 Consumer, direct 940 1,147 Consumer 1,193 1,476 Total acquired loans $ 413,248 $ 414,847 Loans, net of deferred fees and costs $ 2,402,328 $ 2,357,137 Peoples has acquired various loans through business combinations for which there was, at acquisition, evidence of deterioration of credit quality since origination, and for which it was probable that all contractually required payments would not be collected. The carrying amounts of these purchased credit impaired loans included in the loan balances above are summarized as follows: (Dollars in thousands) March 31, December 31, Commercial real estate, other $ 7,794 $ 8,117 Commercial and industrial 718 767 Residential real estate 19,156 19,532 Consumer 27 33 Total outstanding balance $ 27,695 $ 28,449 Net carrying amount $ 18,864 $ 19,564 Changes in the accretable yield for purchased credit impaired loans for the three months ended March 31, 2018 were as follows: For the three moths ended (Dollars in thousands) March 31, March 31, Balance, December 31, 2017 $ 6,704 $ 7,132 Accretion (412 ) (461 ) Balance, March 31, 2018 $ 6,292 $ 6,671 Peoples completes annual re-estimations of cash flows on acquired purchased credit impaired loans in August of each year. At the end of each quarter, Peoples evaluates factors to determine if a material change has occurred in acquired loans accounted for and if a re-estimation is needed. Factors evaluated to determine if a re-estimation is needed include changes in: risk ratings, maturity dates, charge-offs, payoffs, nonaccrual status and loans that have become past due. Cash flows expected to be collected on purchased credit impaired loans are estimated by incorporating several key assumptions, similar to the initial estimate of fair value. These key assumptions include probability of default and the amount of actual prepayments after the acquisition date. Prepayments affect the estimated life of the loans and could change the amount of interest income and possibly the principal expected to be collected. In re-forecasting future estimated cash flows, credit loss expectations are adjusted as necessary. Peoples pledges certain loans secured by 1-4 family and multifamily residential mortgages under a blanket collateral agreement to secure borrowings from the FHLB. The amount of such pledged loans totaled $486.5 million and $487.2 million at March 31, 2018 and December 31, 2017 , respectively. Peoples also pledges commercial loans to secure borrowings with the FRB. The outstanding balances of these loans totaled $71.5 million and $74.0 million at March 31, 2018 and December 31, 2017 , respectively. Nonaccrual and Past Due Loans A loan is considered past due if any required principal and interest payments have not been received as of the date such payments were required to be made under the terms of the loan agreement.

Credit Quality Indicators As discussed in Note 1 of the Notes to the Consolidated Financial Statements included in Peoples' 2017 Form 10-K, Peoples categorizes the majority of its loans into risk categories based upon an established risk grading matrix using a scale of 1 to 8. A description of the general characteristics of the risk grades used by Peoples is as follows: “Pass” (grades 1 through 4): Loans in this risk category involve borrowers of acceptable-to-strong credit quality and risk who have the apparent ability to satisfy their loan obligations. Loans in this risk grade would possess sufficient mitigating factors, such as adequate collateral or strong guarantors possessing the capacity to repay the loan if required, for any weakness that may exist. “Special Mention” (grade 5): Loans in this risk grade are the equivalent of the regulatory definition of “Other Assets Especially Mentioned.” Loans in this risk category possess some credit deficiency or potential weakness, which requires a high level of management attention. Potential weaknesses include declining trends in operating earnings and cash flows and/or reliance on a secondary source of repayment. If left uncorrected, these potential weaknesses may result in noticeable deterioration of the repayment prospects for the loan or in Peoples' credit position. “Substandard” (grade 6): Loans in this risk grade are inadequately protected by the borrower's current financial condition and payment capability or the collateral pledged, if any. Loans so classified have one or more well-defined weaknesses that jeopardize the orderly repayment of the loan. They are characterized by the distinct possibility that Peoples will sustain some loss if the deficiencies are not corrected. “Doubtful” (grade 7): Loans in this risk grade have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or orderly repayment in full, on the basis of current existing facts, conditions and values, highly questionable and improbable. Possibility of loss is extremely high, but because of certain important and reasonably specific factors that may work to the advantage and strengthening of the exposure, classification of the loan as an estimated loss is deferred until its more exact status may be determined. “Loss” (grade 8): Loans in this risk grade are considered to be non-collectible and of such little value that their continuance as bankable assets is not warranted. This does not mean a loan has absolutely no recovery value, but rather it is neither practical nor desirable to defer writing off the loan, even though partial recovery may be obtained in the future. Charge-offs against the allowance for loan losses are taken in the period in which the loan becomes uncollectible. Consequently, Peoples typically does not maintain a recorded investment in loans within this category. Consumer loans and other smaller-balance loans are evaluated and categorized as “substandard,” “doubtful,” or “loss” based upon the regulatory definition of these classes and consistent with regulatory requirements. All other loans not evaluated individually, nor meeting the regulatory conditions to be categorized as described above, would be considered as being “not rated.” The following table summarizes the risk category of loans within Peoples' loan portfolio based upon the most recent analysis performed: Pass Rated (Grades 1 - 4) Special Mention (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) March 31, 2018 Originated loans: Commercial real estate, construction $ 92,383 $ 6,190 $ 732 $ — $ 452 $ 99,757 Commercial real estate, other 596,903 14,058 16,971 — — 627,932 Commercial real estate 689,286 20,248 17,703 — 452 727,689 Commercial and industrial 404,591 46,477 4,175 — — 455,243 Residential real estate 17,037 579 11,270 131 273,873 302,890 Home equity lines of credit 454 — — — 87,268 87,722 Consumer, indirect 51 6 — — 347,550 347,607 Consumer, direct 37 — — — 67,349 67,386 Consumer 88 6 — — 414,899 414,993 Deposit account overdrafts — — — — 543 543 Total originated loans $ 1,111,456 $ 67,310 $ 33,148 $ 131 $ 777,035 $ 1,989,080 Acquired loans: Commercial real estate, construction $ 8,003 $ — $ 51 $ — $ — $ 8,054 Commercial real estate, other 144,647 3,440 7,918 110 — 156,115 Commercial real estate 152,650 3,440 7,969 110 — 164,169 Commercial and industrial 31,351 185 2,279 — — 33,815 Residential real estate 11,633 647 1,024 — 180,759 194,063 Home equity lines of credit 44 — — — 19,964 20,008 Consumer, indirect 8 — — — 245 253 Consumer, direct 32 — — — 908 940 Consumer 40 — — — 1,153 1,193 Total acquired loans $ 195,718 $ 4,272 $ 11,272 $ 110 $ 201,876 $ 413,248 Total loans $ 1,307,174 $ 71,582 $ 44,420 $ 241 $ 978,911 $ 2,402,328 Pass Rated (Grades 1 - 4) Special Mention (Grade 5) Substandard (Grade 6) Doubtful (Grade 7) Not Rated Total Loans (Dollars in thousands) December 31, 2017 Originated loans: Commercial real estate, construction $ 100,409 $ 5,502 $ 754 $ — $ 453 $ 107,118 Commercial real estate, other 561,320 17,189 16,938 — — 595,447 Commercial real estate 661,729 22,691 17,692 — 453 702,565 Commercial and industrial 420,477 13,062 4,512 — — 438,051 Residential real estate 17,896 1,000 11,371 216 274,040 304,523 Home equity lines of credit 454 — — — 88,448 88,902 Consumer, indirect 55 8 — — 340,327 340,390 Consumer, direct 33 — — — 66,977 67,010 Consumer 88 8 — — 407,304 407,400 Deposit account overdrafts — — — — 849 849 Total originated loans $ 1,100,644 $ 36,761 $ 33,575 $ 216 $ 771,094 $ 1,942,290 Acquired loans: Commercial real estate, construction $ 8,267 $ — $ 52 $ — $ — $ 8,319 Commercial real estate, other 149,486 6,527 9,107 — — 165,120 Commercial real estate 157,753 6,527 9,159 — — 173,439 Commercial and industrial 32,011 157 2,325 — — 34,493 Residential real estate 12,543 593 1,105 — 170,623 184,864 Home equity lines of credit 124 — — — 20,451 20,575 Consumer, indirect 12 — — — 317 329 Consumer, direct 35 — — — 1,112 1,147 Consumer 47 — — — 1,429 1,476 Total acquired loans $ 202,478 $ 7,277 $ 12,589 $ — $ 192,503 $ 414,847 Total loans $ 1,303,122 $ 44,038 $ 46,164 $ 216 $ 963,597 $ 2,357,137 In the first three months of 2018, Peoples' classified loans, which are loans categorized as substandard or doubtful, declined compared to the balances at December 31, 2017 mostly due to loan payoffs.

In assessing whether or not a borrower is experiencing financial difficulties, Peoples considers information currently available regarding the financial condition of the borrower. This information includes, but is not limited to, whether (i) the borrower is currently in payment default on any of the borrower's debt; (ii) a payment default is probable in the foreseeable future without the modification; (iii) the borrower has declared or is in the process of declaring bankruptcy; and (iv) the borrower's projected cash flow is insufficient to satisfy contractual payments due under the original terms of the loan without a modification. Peoples considers all aspects of the modification to loan terms to determine whether or not a concession has been granted to the borrower. Key factors considered by Peoples include the borrower's ability to access funds at a market rate for debt with similar risk characteristics, the significance of the modification relative to the unpaid principal balance or collateral value of the debt, and the significance of a delay in the timing of payments relative to the original contractual terms of the loan. The most common concessions granted by Peoples generally include one or more modifications to the terms of the loan, such as (i) a reduction in the interest rate for the remaining life of the loan, (ii) an extension of the maturity date at an interest rate lower than the current market rate for new loans with similar risk, (iii) a temporary period of interest-only payments, and (iv) a reduction in the contractual payment amount for either a short period or the remaining term of the loan.

Decreases in expected cash flows of acquired purchased credit impaired loans are recognized as an impairment, with the amount of the expected loss included in management's evaluation of the appropriateness of the allowance for loan losses. The methods utilized to estimate the required allowance for loan losses for nonimpaired acquired loans are similar to those utilized for originated loans; however, Peoples records a provision for loan losses only when the computed allowance exceeds the remaining fair value adjustment.
