Accounting Policies [Abstract]
Basis of Presentation of Interim Financial Information	Basis of Presentation of Interim Financial Information The accompanying unaudited Condensed Consolidated Financial Statements of Heidrick & Struggles International, Inc. and subsidiaries (the “Company”) have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Significant items subject to estimates and assumptions include revenue recognition, income taxes, interim effective tax rate and assessment of goodwill and other intangible assets for impairment. Estimates are subject to a degree of uncertainty and actual results could differ from these estimates. These financial statements and notes are to be read in conjunction with the Company’s Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 , as filed with the SEC on March 10, 2016 .

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies A complete listing of the Company’s significant accounting policies is discussed in Note 2, Summary of Significant Accounting Policies , in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 . Recently Issued Financial Accounting Standards In August 2016, the Financial Accounting Standards Board ("FASB") issued accounting Standards Update ("ASU") No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, which is intended to reduce diversity in practice as to how certain cash receipts and cash payments should be presented and classified. The standard is effective for interim and annual reporting periods beginning after December 15, 2017 with early adoption permitted. The Company has evaluated the standard and noted the guidance for contingent consideration payments made after a business combination are applicable to the Condensed Consolidated Statements of Cash Flows. The Company currently classifies all contingent consideration payments as financing activities. The impact of this change is not expected to be significant to the classification of these activities on the Consolidated Statements of Cash Flows. In March 2016, the FASB issued ASU No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting , which is intended to simplify several aspects of the accounting for share-based payment transactions including the income tax accounting, classification of awards as either equity or liabilities, the accounting for forfeitures and classification on the statement of cash flows. The standard is effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company is planning to early adopt this standard during the fourth quarter of 2016. The impact of this change is not expected to be significant to Condensed Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, Leases , intended to improve financial reporting about leasing transactions. The new guidance will require entities that lease assets to recognize on their balance sheets the assets and liabilities for the rights and obligations created by those leases and to disclose key information about the leasing arrangements. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted. The guidance requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time. In January 2016, the FASB issued ASU 2016-01, Financial Instruments: Recognition and Measurement of Financial Assets and Financial Liabilities , which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments including the recognition of unrealized changes in fair value within net income. The standard is effective for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The ASU requires that an entity recognizes revenue to depict the transfer of promised goods or services to customer in an amount that reflects the consideration to which the Company expects to be entitled in exchange for these goods or services. The effective date has been deferred for one year to the interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of the original effective date, which was interim and annual reporting periods beginning after December 15, 2016. The guidance permits the use of either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 – Quoted prices in active markets for identical assets and liabilities. • Level 2 – Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The following tables provide a summary of the fair value measurements at September 30, 2016 and December 31, 2015 for each major category of assets and liabilities measured at fair value on a recurring basis: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total At September 30, 2016 U.S. non-qualified deferred compensation plan $ 17,268 $ — $ — $ 17,268 Assets designated for retirement and pension plans — 18,790 — 18,790 Acquisition earnout accruals — — (9,790 ) (9,790 ) $ 17,268 $ 18,790 $ (9,790 ) $ 26,268 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total At December 31, 2015 U.S. non-qualified deferred compensation plan $ 14,145 $ — $ — $ 14,145 Assets designated for retirement and pension plans — 18,164 — 18,164 Acquisition earnout accruals — — (12,033 ) (12,033 ) $ 14,145 $ 18,164 $ (12,033 ) $ 20,276 The Level 2 assets above are fair valued using a market approach. The Level 3 liabilities include accruals for future earnout payments related to prior acquisitions, the values of which are determined based on discounted cash flow models. The Company considers the recorded value of its financial assets and liabilities, which consist primarily of cash and cash equivalents, accounts receivable, and accounts payable, to approximate the fair value of the respective assets and liabilities at September 30, 2016 and December 31, 2015 based upon the short-term nature of the assets and liabilities.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-based Compensation	Stock-Based Compensation The Company’s 2012 Heidrick & Struggles GlobalShare Program (the “2012 Program”) provides for grants of stock options, stock appreciation rights, and other stock-based awards that are valued based upon the grant date fair value of shares. These awards may be granted to directors, selected employees and independent contractors. The 2012 Program originally authorized 1,300,000 shares of Common Stock for issuance pursuant to awards under the plan. On May 22, 2014 , the stockholders of the Company approved an amendment to the 2012 Program to increase the number of shares of Common Stock reserved for issuance under the 2012 Program by 700,000 shares. As of September 30, 2016 , 1,397,410 awards have been issued under the 2012 Program and 1,003,228 shares remain available for future awards, which includes 400,638 forfeited awards. The 2012 Program provides that no awards can be granted after May 24, 2022 . The Company measures its stock-based compensation costs based on the grant date fair value of the awards and recognizes these costs in the financial statements over the requisite service period. A summary of information with respect to stock-based compensation is as follows: Three Months Ended Nine Months Ended 2016 2015 2016 2015 Salaries and employee benefits $ 1,155 $ 1,094 $ 4,492 $ 3,234 General and administrative expenses — — 563 450 Income tax benefit related to stock-based compensation included in net income 437 259 2,005 1,301 Restricted Stock Units Restricted stock unit activity for the nine months ended September 30, 2016 : Number of Weighted- Outstanding on December 31, 2015 473,935 $ 19.98 Granted 207,405 22.92 Vested and converted to common stock (119,455 ) 20.02 Forfeited (24,612 ) 22.81 Outstanding on September 30, 2016 537,273 20.97 As of September 30, 2016 , there was $4.4 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 2.0 years. Performance Stock Units The Company grants performance stock units to certain of its senior executives. The performance stock units are generally subject to a cliff vesting at the end of a three year period. The vesting will vary between 0% — 200% based on the attainment of operating income goals over the three year vesting period. The performance stock units are expensed on a straight-line basis over the three year vesting period. In 2014, the Company granted market-based performance stock units to the Chief Executive Officer. The market-based awards vest after a two year service period and if the price of the Company’s common stock exceeds specified targets. The fair value of the market-based awards was determined using the Monte-Carlo simulation model. A Monte Carlo simulation model uses stock price volatility and other variables to estimate the probability of satisfying the market conditions and the resulting fair value of the award. Compensation costs related to the market-based awards are recognized regardless of whether the market condition is satisfied, as long as the requisite service has been provided. All of the market-based performance conditions were satisfied such that all 125,000 performance stock units granted to the Chief Executive Officer vested upon the completion of the two year service period in February 2016. Performance stock unit activity for the nine months ended September 30, 2016 : Number of Stock Units Weighted- Outstanding on December 31, 2015 272,024 $ 18.28 Granted 125,388 22.98 Vested and converted to common stock (160,600 ) 15.51 Outstanding on September 30, 2016 236,812 22.64 As of September 30, 2016 , there was $2.6 million of pre-tax unrecognized compensation expense related to unvested performance stock units, which is expected to be recognized over a weighted average of 2.1 years.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company operates its executive search and leadership consulting services in the Americas; Europe (which includes Africa); and Asia Pacific (which includes the Middle East) and operates its culture shaping business as a separate segment. For segment purposes, reimbursements of out-of-pocket expenses classified as revenue and other operating income are reported separately and, therefore, are not included in the results of each segment. The Company believes that analyzing trends in revenue before reimbursements (net revenue), analyzing operating expenses as a percentage of net revenue, and analyzing operating income more appropriately reflects its core operations. The revenue and operating income (loss) by segment are as follows: Three Months Ended Nine Months Ended 2016 2015 2016 2015 Revenue: Executive Search and Leadership Consulting Americas $ 78,198 $ 78,265 $ 237,557 $ 218,560 Europe 32,895 25,946 91,017 69,679 Asia Pacific 23,801 25,031 67,325 72,712 Total Executive Search and Leadership Consulting 134,894 129,242 395,899 360,951 Culture Shaping 8,625 9,179 26,670 25,668 Revenue before reimbursements (net revenue) 143,519 138,421 422,569 386,619 Reimbursements 4,720 4,429 13,773 12,396 Total $ 148,239 $ 142,850 $ 436,342 $ 399,015 Three Months Ended Nine Months Ended 2016 2015 2016 2015 Operating income (loss): Executive Search and Leadership Consulting Americas $ 18,552 $ 18,193 $ 56,817 $ 50,563 Europe 2,371 1,470 2,429 1,018 Asia Pacific 2,029 2,630 5,179 8,088 Total Executive Search and Leadership Consulting 22,952 22,293 64,425 59,669 Culture Shaping 41 1,539 (1,928 ) 2,948 Total Segments 22,993 23,832 62,497 62,617 Global Operations Support (10,987 ) (10,899 ) (34,929 ) (33,840 ) Total $ 12,006 $ 12,933 $ 27,568 $ 28,777

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation The Company has contingent liabilities from various pending claims and litigation matters arising in the ordinary course of the Company’s business, some of which involve claims for damages that are substantial in amount. Some of these matters are covered by insurance. Based upon information currently available, the Company believes the ultimate resolution of such claims and litigation, including the “UK Employee Benefits Trust” matter discussed below, will not have a material adverse effect on its financial condition, results of operations or liquidity. UK Employee Benefits Trust On January 27, 2010, HM Revenue & Customs (“HMRC”) in the United Kingdom notified the Company that it was challenging the tax treatment of certain of the Company’s contributions in the United Kingdom to an Employee Benefits Trust between 2002 and 2008. HMRC alleges that these contributions should have been subject to Pay As You Earn tax and Class 1 National Insurance Contributions in the United Kingdom. HMRC is proposing an adjustment to the Company’s payroll tax liability for the affected years. The aggregate amount of HMRC’s proposed adjustment is approximately £3.9 million (equivalent to $5.1 million ) at September 30, 2016 . The Company has appealed the proposed adjustment. At this time, the Company believes that the likelihood of an unfavorable outcome with respect to the proposed adjustment is not probable and the potential amount of any loss cannot be reasonably estimated. The Company also believes that the amount of any final adjustment would not be material to the Company’s financial condition.

Accounting Policies [Abstract]
Recent Financial Accounting Standards	Recently Issued Financial Accounting Standards In August 2016, the Financial Accounting Standards Board ("FASB") issued accounting Standards Update ("ASU") No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, which is intended to reduce diversity in practice as to how certain cash receipts and cash payments should be presented and classified. The standard is effective for interim and annual reporting periods beginning after December 15, 2017 with early adoption permitted. The Company has evaluated the standard and noted the guidance for contingent consideration payments made after a business combination are applicable to the Condensed Consolidated Statements of Cash Flows. The Company currently classifies all contingent consideration payments as financing activities. The impact of this change is not expected to be significant to the classification of these activities on the Consolidated Statements of Cash Flows. In March 2016, the FASB issued ASU No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting , which is intended to simplify several aspects of the accounting for share-based payment transactions including the income tax accounting, classification of awards as either equity or liabilities, the accounting for forfeitures and classification on the statement of cash flows. The standard is effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company is planning to early adopt this standard during the fourth quarter of 2016. The impact of this change is not expected to be significant to Condensed Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, Leases , intended to improve financial reporting about leasing transactions. The new guidance will require entities that lease assets to recognize on their balance sheets the assets and liabilities for the rights and obligations created by those leases and to disclose key information about the leasing arrangements. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted. The guidance requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time. In January 2016, the FASB issued ASU 2016-01, Financial Instruments: Recognition and Measurement of Financial Assets and Financial Liabilities , which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments including the recognition of unrealized changes in fair value within net income. The standard is effective for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The ASU requires that an entity recognizes revenue to depict the transfer of promised goods or services to customer in an amount that reflects the consideration to which the Company expects to be entitled in exchange for these goods or services. The effective date has been deferred for one year to the interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of the original effective date, which was interim and annual reporting periods beginning after December 15, 2016. The guidance permits the use of either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect upon initial adoption recognized at the date of adoption. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time.
