Business	Business Tanger Factory Outlet Centers, Inc. and subsidiaries is one of the largest owners and operators of outlet centers in the United States and Canada. We are a fully-integrated, self-administered and self-managed real estate investment trust ("REIT") which, through our controlling interest in the Operating Partnership, focuses exclusively on developing, acquiring, owning, operating and managing outlet shopping centers. As of June 30, 2015 , we owned and operated 37 outlet centers, with a total gross leasable area of approximately 11.7 million square feet. We also had partial ownership interests in 9 outlet centers totaling approximately 2.7 million square feet, including 4 outlet centers in Canada. Our outlet centers and other assets are held by, and all of our operations are conducted by, Tanger Properties Limited Partnership and subsidiaries. Accordingly, the descriptions of our business, employees and properties are also descriptions of the business, employees and properties of the Operating Partnership. Unless the context indicates otherwise, the term, "Company", refers to Tanger Factory Outlet Centers, Inc. and subsidiaries and the term, "Operating Partnership", refers to Tanger Properties Limited Partnership and subsidiaries. The terms "we", "our" and "us" refer to the Company or the Company and the Operating Partnership together, as the text requires. The Company owns the majority of the units of partnership interest issued by the Operating Partnership through its two wholly-owned subsidiaries, Tanger GP Trust and Tanger LP Trust. Tanger GP Trust controls the Operating Partnership as its sole general partner. Tanger LP Trust holds a limited partnership interest. As of June 30, 2015 , the Company, through its ownership of Tanger GP Trust and Tanger LP Trust, owned 95,842,047 units of the Operating Partnership and other limited partners (the "Non-Company LPs") collectively owned 5,078,406 Class A common limited partnership units. Each Class A common limited partnership unit held by the Non-Company LPs is exchangeable for one of the Company's common shares, subject to certain limitations to preserve the Company's REIT status.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements included herein have been prepared pursuant to accounting principles generally accepted in the United States of America and should be read in conjunction with the consolidated financial statements and notes thereto of the Company's and the Operating Partnership's combined Annual Report on Form 10-K for the year ended December 31, 2014 . The December 31, 2014 balance sheet data in this Form 10-Q was derived from audited financial statements. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the SEC's rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the financial statements for the interim periods have been made. The results of interim periods are not necessarily indicative of the results for a full year. We consolidate properties that are wholly owned or properties where we own less than 100% but we control. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIE"). For joint ventures that are determined to be a VIE, we consolidate the entity where we are deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Our determination of the primary beneficiary considers all relationships between us and the VIE, including management agreements and other contractual arrangements. Investments in real estate joint ventures that we do not control but may exercise significant influence are accounted for using the equity method of accounting. These investments are recorded initially at cost and subsequently adjusted for our equity in the venture's net income or loss, cash contributions, distributions and other adjustments required under the equity method of accounting. For certain of these investments, we record our equity in the venture's net income or loss under the hypothetical liquidation of book value (“HLBV”) method of accounting due to the structures and the preferences we receive on the distributions from our joint ventures pursuant to the respective joint venture agreements for those joint ventures. Under this method, we recognize income and loss in each period based on the change in liquidation proceeds we would receive from a hypothetical liquidation of our investment based on depreciated book value. Therefore, income or loss may be allocated disproportionately as compared to the ownership percentages due to specified preferred return rate thresholds and may be more or less than actual cash distributions received and more or less than what we may receive in the event of an actual liquidation. In the event a basis difference is created between our underlying interest in the venture's net assets and our initial investment, we amortize such amount over the estimated life of the venture as a component of equity in earnings of unconsolidated joint ventures. We separately report investments in joint ventures for which accumulated distributions have exceeded investments in and our share of net income or loss of the joint ventures within other liabilities in the consolidated balance sheets. The carrying amount of our investments in the Charlotte and Galveston/Houston joint ventures are less than zero because of financing or operating distributions that were greater than net income, as net income includes non-cash charges for depreciation and amortization. We have concluded that our Savannah and Southaven joint ventures are each considered a VIE because our voting rights are disproportionate to our economic interests and substantially all of each venture's activities either involve or are conducted on our behalf. Due to certain reconsideration events, we concluded during the quarter that our Westgate joint venture, previously considered a VIE since inception, was no longer considered a VIE. The operating, development, leasing, and management agreements of Savannah provide that the activities that most significantly impact the economic performance of the venture require unanimous consent. Accordingly, we determined that we are not the primary beneficiary since we do not have the power to direct the significant activities that affect the economic performance of the venture, and have applied the equity method of accounting. The carrying amount of our investment in Savannah is reflected in investments in unconsolidated joint ventures on our consolidated balance sheets and was $46.0 million as of June 30, 2015 . We are unable to estimate our maximum exposure to loss at this time because our guarantees are limited and based on the future operating performance of Savannah. The management agreement and other contractual arrangements for Southaven give us, but not necessarily our joint venture partner, significant participating rights over activities that most significantly impact the economic performance of the ventures, thus we have concluded that we are the primary beneficiary and have consolidated the venture's balance sheet and results of operations. At June 30, 2015 , total assets of this venture, which is currently under construction, were $38.6 million and total liabilities were $11.5 million . The primary classification of these assets on the consolidated balance sheets are within cash and total rental property, net and the classification of liabilities is within accounts payable and accrued expenses. These assets include only those assets that can be used to settle obligations of the VIE. The liabilities include third party liabilities and exclude intercompany balances that are eliminated in consolidation. "Noncontrolling interests in the Operating Partnership" reflects the Non-Company LP's percentage ownership of the Operating Partnership's units. "Noncontrolling interests in other consolidated partnerships" consist of outside equity interests in partnerships or joint ventures not wholly owned by the Company or the Operating Partnership that are consolidated with the financial results of the Company and Operating Partnership because the Operating Partnership exercises control over the entities that own the properties. Noncontrolling interests are initially recorded in the consolidated balance sheets at fair value based upon purchase price allocations. Income is allocated to the noncontrolling interests based on the allocation provisions within the partnership or joint venture agreements. In the consolidated statement of operations, we have reclassified $758,000 and $1.3 million related to management, leasing and other services for the three and six months ended June 30, 2014, respectively, to the caption "management, leasing and other services" from the caption "other income" to conform to the presentation of the consolidated statement of operations for the three and six months ended June 30, 2015 . In addition, we have reclassified certain amounts related to other non-operating income and expenses for the three and six months ended June 30, 2014 to the caption " other income/(expense)" from the caption "other income" to conform to the presentation of the consolidated statement of operations for the three and six months ended June 30, 2015 . We have revised the previously reported amounts in the consolidated statement of cash flows to reclassify approximately $2.0 million related to tax increment financing for the six months ended June 30, 2014 to the caption "additions to rental property" from the caption "proceeds from tax increment financing" to conform to the presentation of the consolidated statement of cash flows for the six months ended June 30, 2015 . We have concluded the previously reported financial statements were not materially misstated as a result of this revision.

Disposition of Properties and Properties Held for Sale [Abstract]
Disposition of Properties and Properties Held for Sale	Disposition of Properties and Properties Held for Sale At June 30, 2015, we had a contractual agreement to sell four properties totaling approximately 712,000 square feet classified as rental property held for sale on the consolidated balance sheets. The results of operations for these properties are included in continuing operations as the potential sale did not meet the criteria set forth in the recently adopted guidance requiring the result of operations to be separately set forth as discontinued operations. The carrying values of the rental properties held for sale were comprised of the following (in thousands): June 30, 2015 December 31, 2014 Rental property, net $ 44,252 $ 43,532 Deferred lease costs and other intangibles, net 888 757 Prepaids and other assets 1,722 1,716 Rental property held for sale $ 46,862 $ 46,005 Subsequent to June 30, 2015, we concluded that the sale of these four outlet centers was no longer probable as a result of the buyer's inability to secure acceptable financing. In the third quarter of 2015, we will reclassify the four outlet centers from held for sale to held and used and record an adjustment of approximately $1.6 million representing the depreciation and amortization expense that would have been recognized had the properties been continuously classified as held and used.

Investments In Unconsolidated Real Estate Joint Ventures [Abstract]
Investments in Unconsolidated Real Estate Joint Ventures	Investments in Unconsolidated Real Estate Joint Ventures The equity method of accounting is used to account for each of the individual joint ventures.

Our economic interest may fluctuate based on a number of factors, including mortgage financing, partnership capital contributions and distributions, and proceeds from gains or losses of asset sales. (2) The negative carrying value is due to the distributions of proceeds from mortgage loans and quarterly distributions of excess cash flow exceeding the original contributions from the partners. Fees we received for various services provided to our unconsolidated joint ventures were recognized in management, leasing and other services as follows (in thousands): Three months ended Six months ended June 30, June 30, 2015 2014 2015 2014 Fee: Development and leasing $ 727 $ 70 $ 1,307 $ 78 Loan guarantee 187 146 383 187 Management and marketing 813 542 1,320 1,059 Total Fees $ 1,727 $ 758 $ 3,010 $ 1,324 Our investments in real estate joint ventures are reduced by the percentage of the profits earned for leasing and development services associated with our ownership interest in each joint venture. Our carrying value of investments in unconsolidated joint ventures differs from our share of the assets reported in the "Summary Balance Sheets - Unconsolidated Joint Ventures" shown below due to adjustments to the book basis, including intercompany profits on sales of services that are capitalized by the unconsolidated joint ventures. The differences in basis (totaling $4.0 million and $4.4 million as of June 30, 2015 and December 31, 2014 , respectively) are amortized over the various useful lives of the related assets. Columbus, Ohio During the second quarter of 2015, the joint venture purchased land for approximately $8.9 million and began construction on Tanger Outlets Columbus. We and our partner currently expect to complete construction in time to open the center during the second quarter of 2016. Our partner is providing development services to the joint venture and we, along with our partner, are providing joint leasing services. Once the center opens, we will provide property management, marketing and leasing services to the joint venture. Savannah, Georgia In January 2014, we announced a joint venture arrangement to develop Tanger Outlets Savannah. The center, which opened in April 2015, includes approximately 377,000 square feet. As of June 30, 2015 , our equity contributions totaled $45.8 million and our partner’s equity contributions totaled $8.3 million . Contributions we made in excess of our partners' equity contributions earned a preferred rate of return equal to 8% from the date the contributions were made until the outlet center’s grand opening in April 2015, and will earn 10% annually thereafter. The joint venture has an interest only mortgage loan with the ability to borrow up to $97.7 million , of which $4.7 million will be available for future expansion, at an interest rate of LIBOR + 1.65% . The loan initially matures on May 21, 2017, with two , one -year extension options. As of June 30, 2015 , the balance on the loan was $70.1 million . We are providing development, management and marketing services to the joint venture; and with our partner, are jointly providing leasing services to the outlet center. Westgate, Glendale, Arizona During the first quarter of 2015, the joint venture completed the remaining 28,000 square feet of a 78,000 square foot expansion of the existing property which brought the size of the outlet center to approximately 411,000 square feet. Construction commenced on the expansion during the second quarter of 2014 and was funded with borrowings under the amended Westgate mortgage loan. The joint venture's amended and restated construction loan has the ability to borrow up to $62.0 million . The loan initially matured in June 2015, and during the second quarter of 2015 the joint venture exercised the two year option to extend the maturity date of the loan to June 2017. As of June 30, 2015 , the balance on the loan was $62.0 million . Tanger Outlets Westgate opened in November 2012 and was developed through, and is currently owned by, a joint venture that was formed in May 2012. We are providing property management, construction supervision, marketing and leasing services to the joint venture. Wisconsin Dells, Wisconsin In February 2015, we sold our equity interest in the joint venture that owned an outlet center in Wisconsin Dells, Wisconsin for approximately $15.6 million , representing our share of the sales price totaling $27.7 million less our share of the outstanding debt, which totaled $12.1 million . As a result of this transaction, we recorded a gain of approximately $13.7 million in the first quarter of 2015, which represents the difference between the carrying value of our equity method investment and the net proceeds received.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers are defined as follows: Tier Description Level 1 Observable inputs such as quoted prices in active markets Level 2 Inputs other than quoted prices in active markets that are either directly or indirectly observable Level 3 Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions The following table sets forth our assets and liabilities that are measured at fair value within the fair value hierarchy (in thousands): Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Observable Inputs Significant Unobservable Inputs Total Fair value as of June 30, 2015: Liabilities: Interest rate swaps (other liabilities) $ (794 ) $ — $ (794 ) $ — Total liabilities $ (794 ) $ — $ (794 ) $ — Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Observable Inputs Significant Unobservable Inputs Total Fair value as of December 31, 2014: Assets: Interest rate swaps (prepaids and other assets) $ 95 $ — $ 95 $ — Total assets $ 95 $ — $ 95 $ — The estimated fair value and recorded value of our debt consisting of senior unsecured notes, unsecured term loans, secured mortgages and unsecured lines of credit were as follows (in thousands): June 30, 2015 December 31, 2014 Fair value of debt $ 1,572,370 $ 1,493,519 Recorded value of debt 1,514,490 1,443,194 With the exception of the unsecured term loan and unsecured lines of credit, that have variable rates and considered at market value, fair values of the senior notes and mortgage loans are determined using discounted cash flow analysis with an interest rate or credit spread similar to that of current market borrowing arrangements. Because the Company's senior unsecured notes are publicly traded with limited trading volume, these instruments are classified as Level 2 in the hierarchy. In contrast, mortgage loans are classified as Level 3 given the unobservable inputs utilized in the valuation. Considerable judgment is necessary to develop estimated fair values of financial instruments. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize on the disposition of the financial instruments. The carrying values of cash and cash equivalents, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the short maturities of these instruments.

Notional units granted in 2010 were converted into 933,769 restricted common shares in January 2014. The restricted common shares vested on December 31, 2014 and were considered participating securities through the vesting date. The computation of diluted earnings per share excludes options to purchase common shares when the exercise price is greater than the average market price of the common shares for the period. For the three and six months ended June 30, 2015 , 250,700 and 250,800 options were excluded from the computation, respectively. For the both the three and six months ended June 30, 2014 , 276,500 options were excluded from the computation. The assumed exchange of the partnership units held by the Non-Company LPs as of the beginning of the year, which would result in the elimination of earnings allocated to the noncontrolling interest in the Operating Partnership, would have no impact on earnings per share since the allocation of earnings to a common limited partnership unit, as if exchanged, is equivalent to earnings allocated to a common share. Certain of the Company's unvested restricted common share awards contain non-forfeitable rights to dividends or dividend equivalents. The impact of these unvested restricted common share awards on earnings per share has been calculated using the two-class method whereby earnings are allocated to the unvested restricted common share awards based on dividends declared and the unvested restricted common shares' participation rights in undistributed earnings. Unvested restricted common shares that do not contain non-forfeitable rights to dividends or dividend equivalents are included in the diluted earnings per share computation if the effect is dilutive, using the treasury stock method.

Equity Based Compensation of the Company	Equity Based Compensation of the Company We have a shareholder approved equity-based compensation plan, the Incentive Award Plan of Tanger Factory Outlet Centers and Tanger Properties Limited Partnership (Amended and Restated as of April 4, 2014) (the "Plan"), which covers our independent directors, officers, employees and consultants. For each common share issued by the Company, the Operating Partnership issues one corresponding unit of partnership interest to the Company's wholly owned subsidiaries. Therefore, when the Company grants an equity based award, the Operating Partnership treats each award as having been granted by the Operating Partnership. In the discussion below, the term "we" refers to the Company and the Operating Partnership together and the term "shares" is meant to also include corresponding units of the Operating Partnership. During February 2015, the Company issued 357,844 restricted common shares to the Company's independent directors and the Company's senior executive officers. The grant date fair value of the awards ranged from $32.77 to $38.55 per share. The independent directors' restricted common shares vest ratably over a three year period and the senior executive officers' restricted shares vest ratably over a five year period. For the restricted shares issued to our chief executive officer, the restricted share agreement requires him to hold the shares for a minimum of three years following each vesting date. Compensation expense related to the amortization of the deferred compensation is being recognized in accordance with the vesting schedule of the restricted shares. In February 2015, the Compensation Committee of the Company approved the general terms of the Tanger Factory Outlet Centers, Inc. 2015 Outperformance Plan (the “2015 OPP"). The 2015 OPP is a long-term performance based incentive compensation plan pursuant to which award recipients may earn up to an aggregate of 306,600 restricted common shares based on the Company’s absolute share price appreciation (or total shareholder return) and its share price appreciation relative to its peer group, over a three year measurement period from January 1, 2015 through December 31, 2017.

The total number of shares withheld was 30,578 for the six months ended June 30, 2015 , and was based on the value of the restricted common shares on the vesting date as determined by our closing share price on the day prior to the vesting date. No shares were withheld for the three months ended June 30, 2015 or for the three and six months ended June 30, 2014.

New Accounting Standards [Abstract]
New Accounting Standards	New Accounting Standards In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. The guidance in the new standard is limited to the presentation of debt issuance costs. The standard does not affect the recognition and measurement of debt issuance costs. Early adoption is permitted for financial statements that have not been previously issued. The new guidance will be applied on a retrospective basis. The standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. We do not expect the adoption of ASU 2015-03 to have a material impact on our consolidated financial statements. In February 2015, FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership and affects the consolidation analysis reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. ASU 2015-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15 Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, and to provide certain disclosures when it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued. ASU 2014-15 is effective for the annual period ended December 31, 2016 and for annual periods and interim periods thereafter with early adoption permitted. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements. In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (the "Final Standard"). Under the Final Standard, only disposals representing a strategic shift in operations ( e.g. , a disposal of a major geographic area, a major line of business or a major equity method investment) will be presented as discontinued operations. Under current GAAP, companies that sell a single investment property are generally required to report the sale as a discontinued operation, which requires the companies to reclassify earnings from continuing operations for all periods presented. The Final Standard is effective in the first quarter of 2015 for public entities with calendar year ends. The FASB will permit early adoption of the Final Standard, beginning in the first quarter of 2014, but only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. We early adopted the standard in the first quarter of 2014. See Note 3 Disposition of Properties and Properties Held for Sale for further information. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We are required to adopt the new pronouncement in the first quarter of fiscal 2018 using one of two retrospective application methods. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements.
