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, 2016 , as filed with the SEC on March 23, 2017 .

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, 2016 . Recently Issued Financial Accounting Standards In March 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-07, Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which is intended to improve the consistency, transparency and usefulness of net benefit cost disclosures. ASU 2017-07 requires that an employer report the service cost component of net benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Additionally, the other components of net benefit costs are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. ASU 2017-07 is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted. The Company has not yet determined when it will adopt this guidance. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other, which eliminates Step 2 from the goodwill impairment test. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, and entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. ASU 2017-04 is effective for interim and annual periods beginning after December 15, 2019 with early adoption permitted. The Company has not yet determined when it will adopt this guidance. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore amounts generally described as restricted cash should be included with cash and cash equivalents when recording the beginning of period and end of period total amounts shown on the statement of cash flows. The Company currently does not include restricted cash amounts in the beginning and ending cash amounts and will change the presentation of the cash flow statement to include restricted cash in the beginning and ending cash totals. The standard is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted.The Company has not yet determined when it will adopt this guidance. If the Company had adopted the guidance as of March 31, 2017, the beginning and ending balance of cash and cash equivalents for the three months ended March 31, 2017 would have each increased by $0.6 million in the Condensed Consolidated Statement of Cash Flows. 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 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 customers 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. The guidance permits the use of either of the following transition methods: (i) a full retrospective method reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective method with the cumulative effect upon initial adoption recognized at the date of initial application (modified retrospective). The Company will adopt the guidance on January 1, 2018 and will apply the modified retrospective method. The Company is performing its evaluation of ASU No. 2014-09. The Company is paid a retainer for its executive search services equal to approximately one-third of the estimated first year compensation for the position to be filled. If the actual compensation of a placed candidate exceeds the estimated compensation, the Company is often authorized to bill the client for one-third of the excess. The Company currently recognizes revenue associated with the difference between the estimated compensation and actual compensation at the time this amount is considered fixed and determinable. Under ASU 2014-09, the difference between estimated compensation and actual compensation is considered variable consideration. The Company will be required to estimate the amount of variable consideration for its executive search services at contract inception. The Company is still evaluating the financial impact of this change. The Company is continuing to evaluate the impacts of adoption of this guidance and its preliminary assessments are subject to change. Reclassifications Certain prior year amounts have been recast as a result of the change in the Company's operating segments as first reported in the Company's Annual Report on Form 10-K filed on March 23, 2017. The reclassifications had no impact on net income, net cash flows or stockholders' equity. Earnings per Common Share Basic earnings per common share is computed by dividing net income by weighted average common shares outstanding for the year. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted. Common equivalent shares are excluded from the determination of diluted earnings per share in periods in which they have an anti-dilutive effect. The following table sets forth the computation of basic and diluted earnings per share: Three Months Ended 2017 2016 Net Income $ 650 $ 1,325 Weighted average shares outstanding: Basic 18,628 18,448 Effect of dilutive securities: Restricted stock units 431 328 Performance stock units 160 203 Diluted 19,219 18,979 Basic earnings per share $ 0.03 $ 0.07 Diluted earnings per share $ 0.03 $ 0.07

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 March 31, 2017 and December 31, 2016 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 Balance at March 31, 2017 U.S. non-qualified deferred compensation plan $ 19,763 $ — $ — $ 19,763 Assets designated for retirement and pension plans — 17,193 — 17,193 Pension benefit obligation — (22,435 ) — (22,435 ) Acquisition earnout accruals — — (9,379 ) (9,379 ) $ 19,763 $ (5,242 ) $ (9,379 ) $ 5,142 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Balance at December 31, 2016 U.S. non-qualified deferred compensation plan $ 17,346 $ — $ — $ 17,346 Assets designated for retirement and pension plans — 16,979 — 16,979 Pension benefit obligation — (22,128 ) — (22,128 ) Acquisition earnout accruals — — (10,991 ) (10,991 ) $ 17,346 $ (5,149 ) $ (10,991 ) $ 1,206 The Level 2 assets above are reinsurance contracts fair valued in accordance with BaFin - German Federal Financial Supervisory Authority guidelines, which utilize observable inputs including mortality tables and discount rates. 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 March 31, 2017 and December 31, 2016 based upon the short-term nature of the assets and liabilities. The following table provides a reconciliation of the beginning and ending balance of Level 3 assets and liabilities for the three months ended March 31, 2017 . Acquisition Balance at December 31, 2016 $ (10,991 ) Earnout accretion (426 ) Earnout payments 2,172 Foreign currency translation (134 ) Balance at March 31, 2017 $ (9,379 )

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 March 31, 2017 , 1,713,996 awards have been issued under the 2012 Program and 686,642 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 2017 2016 Salaries and employee benefits $ 1,640 $ 1,831 Income tax benefit related to stock-based compensation included in net income 647 737 Restricted Stock Units Restricted stock unit activity for the three months ended March 31, 2017 : Number of Weighted- Outstanding on December 31, 2016 537,273 $ 20.97 Granted 228,171 24.30 Vested and converted to common stock (181,964 ) 21.12 Forfeited — — Outstanding on March 31, 2017 583,480 22.23 As of March 31, 2017 , there was $7.4 million of pre-tax unrecognized compensation expense related to unvested restricted stock units, which is expected to be recognized over a weighted average of 2.4 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 three months ended March 31, 2017 : Number of Stock Units Weighted- Outstanding on December 31, 2016 236,812 $ 22.64 Granted 88,415 23.83 Vested and converted to common stock (70,652 ) 19.65 Forfeited — — Outstanding on March 31, 2017 254,575 23.89 As of March 31, 2017 , there was $3.8 million of pre-tax unrecognized compensation expense related to unvested performance stock units, which is expected to be recognized over a weighted average of 2.3 years .

Accounting Policies [Abstract]
Recent Financial Accounting Standards	Recently Issued Financial Accounting Standards In March 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-07, Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which is intended to improve the consistency, transparency and usefulness of net benefit cost disclosures. ASU 2017-07 requires that an employer report the service cost component of net benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Additionally, the other components of net benefit costs are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. ASU 2017-07 is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted. The Company has not yet determined when it will adopt this guidance. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other, which eliminates Step 2 from the goodwill impairment test. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, and entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. ASU 2017-04 is effective for interim and annual periods beginning after December 15, 2019 with early adoption permitted. The Company has not yet determined when it will adopt this guidance. The Company is currently evaluating the impact of this accounting guidance. The effect is not known or reasonably estimable at this time. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore amounts generally described as restricted cash should be included with cash and cash equivalents when recording the beginning of period and end of period total amounts shown on the statement of cash flows. The Company currently does not include restricted cash amounts in the beginning and ending cash amounts and will change the presentation of the cash flow statement to include restricted cash in the beginning and ending cash totals. The standard is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted.The Company has not yet determined when it will adopt this guidance. If the Company had adopted the guidance as of March 31, 2017, the beginning and ending balance of cash and cash equivalents for the three months ended March 31, 2017 would have each increased by $0.6 million in the Condensed Consolidated Statement of Cash Flows. 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 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.
Earnings Per Share [Text Block]	Earnings per Common Share Basic earnings per common share is computed by dividing net income by weighted average common shares outstanding for the year. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted. Common equivalent shares are excluded from the determination of diluted earnings per share in periods in which they have an anti-dilutive effect. The following table sets forth the computation of basic and diluted earnings per share: Three Months Ended 2017 2016 Net Income $ 650 $ 1,325 Weighted average shares outstanding: Basic 18,628 18,448 Effect of dilutive securities: Restricted stock units 431 328 Performance stock units 160 203 Diluted 19,219 18,979 Basic earnings per share $ 0.03 $ 0.07 Diluted earnings per share $ 0.03 $ 0.07
