Nature of Business and Basis of Presentation (Policies)	Aug. 02, 2014
Accounting Policies [Abstract]
Fiscal Year	Fiscal Year—We use a fiscal calendar widely used by the retail industry that results in a fiscal year consisting of a 52- or 53-week period ending on the Saturday closest to January 31. Each fiscal year consists of four 13-week quarters, with an extra week added to the fourth quarter every five or six years. The six months ended August 2, 2014 and August 3, 2013 were 26-week periods.
Basis of Presentation	Basis of Presentation—The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited condensed consolidated financial statements include the accounts of Zumiez Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation. In our opinion, the unaudited condensed consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the condensed consolidated balance sheets, operating results and cash flows for the periods presented. The financial data at February 1, 2014 is derived from audited consolidated financial statements, which are included in our Annual Report on Form 10-K for the year ended February 1, 2014, and should be read in conjunction with the audited consolidated financial statements and notes thereto. Interim results are not necessarily indicative of results for the full fiscal year due to seasonality and other factors.
Use of Estimates	Use of Estimates—The preparation of financial statements in conformity with U.S. GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements as well as the reported amounts of revenues and expenses during the reporting period. These estimates can also affect supplemental information disclosed by us, including information about contingencies, risk and financial condition. Actual results could differ from these estimates and assumptions.
Segment Reporting	Segment Reporting—We identify our operating segments according to how our business activities are managed and evaluated. Our operating segments have been aggregated and are reported as one reportable segment based on the similar nature of products sold, production, merchandising and distribution processes involved, target customers and economic characteristics.
Recent Accounting Standards	Recent Accounting Standards—In June 2014, the Financial Accounting Standards Board (“FASB”) issued guidance which requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. The guidance allows for a prospective adoption to all awards granted or modified after the effective date or retrospective adoption to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statement and to all new or modified awards thereafter. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2015, with early adoption permitted. We early adopted this guidance for the fiscal quarter ended August 2, 2014 and the adoption did not have a material impact on our condensed consolidated financial statements. In May 2014, the FASB issued a comprehensive new revenue recognition standard. The new standard allows for a full retrospective approach to transition or a modified retrospective approach. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2016. We will adopt this guidance for the fiscal quarter ending April 29, 2017. We are currently evaluating the method of adoption we plan to use and the effect the standard is expected to have on our financial position, results of operations and cash flows. In April 2014, the FASB issued guidance that changes the criteria for reporting discontinued operations, as well as requiring new disclosures about discontinued operations and disposals of components of an entity that do not qualify for discontinued operations reporting. This guidance is effective for fiscal years beginning after December 15, 2014, with early adoption permitted for disposals that have not been reported in financial statements previously issued. We will adopt this guidance for the fiscal quarter ending May 2, 2015 and we do not expect the adoption will have a material impact on our condensed consolidated financial statements.

Disclosure of accounting policy for determining an entity's fiscal year or other fiscal period. This disclosure may include identification of the fiscal period end-date, the length of the fiscal period, any reporting period lag between the entity and its subsidiaries, or equity investees. If a reporting lag exists, the closing date of the entity having a different period end is generally noted, along with an explanation of the necessity for using different closing dates. Any intervening events that materially affect the entity's financial position or results of operations are generally also disclosed.
