Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of presentation. The accompanying unaudited interim condensed consolidated financial statements have been prepared from the records of Ross Stores, Inc. and subsidiaries (the “Company”) without audit and, in the opinion of management, include all adjustments (consisting of only normal, recurring adjustments) necessary to present fairly the Company’s financial position as of August 1, 2015 and August 2, 2014 , the results of operations and comprehensive income for the three and six month periods ended August 1, 2015 and August 2, 2014 , and cash flows for the six month periods ended August 1, 2015 and August 2, 2014 . The Condensed Consolidated Balance Sheet as of January 31, 2015 , presented herein, has been derived from the Company’s audited consolidated financial statements for the fiscal year then ended. Accounting policies followed by the Company are described in Note A to the audited consolidated financial statements for the fiscal year ended January 31, 2015 . Certain information and disclosures normally included in the notes to annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted for purposes of these interim condensed consolidated financial statements. The interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including notes thereto, contained in the Company’s Annual Report on Form 10-K for the year ended January 31, 2015 . The results of operations and comprehensive income for the three and six month periods ended August 1, 2015 and August 2, 2014 presented herein are not necessarily indicative of the results to be expected for the full fiscal year. Stock dividend. On March 24, 2015, the Company's Board of Directors declared a two -for-one split of the Company's common stock issued in the form of a stock dividend. Stockholders of record as of April 22, 2015 were issued one additional share of common stock on June 11, 2015 for each share held. All share and per share amounts have been adjusted to reflect the stock split. Restricted cash, cash equivalents, and investments. The Company has restricted cash, cash equivalents, and investments that serve as collateral for certain insurance obligations of the Company. These restricted funds are invested in bank deposits, money market mutual funds, U.S. Government and agency securities, and corporate securities and cannot be withdrawn from the Company’s account without the prior written consent of the secured parties. The following table summarizes total restricted cash, cash equivalents, and investments which were included in Prepaid expenses and other and Other long-term assets in the Condensed Consolidated Balance Sheets as of August 1, 2015 , January 31, 2015 , and August 2, 2014 : Restricted Assets ($000) August 1, 2015 January 31, 2015 August 2, 2014 Prepaid expenses and other $ 19,719 $ 19,713 $ 22,766 Other long-term assets 56,125 56,107 55,737 Total $ 75,844 $ 75,820 $ 78,503 The classification between current and long-term is based on the timing of expected payments of the insurance obligations. Property and equipment. As of August 1, 2015 and August 2, 2014 , the Company had $10.0 million and $22.6 million , respectively, of property and equipment purchased but not yet paid. These purchases are included in Property and Equipment, Accounts payable, and Accrued expenses and other in the accompanying Condensed Consolidated Balance Sheets. Sales mix. The Company’s sales mix is shown below for the three and six month periods ended August 1, 2015 and August 2, 2014 : Three Months Ended Six Months Ended August 1, 2015 August 2, 2014 August 1, 2015 August 2, 2014 Ladies 30 % 31 % 30 % 31 % Home Accents and Bed and Bath 23 % 22 % 23 % 22 % Men's 14 % 14 % 13 % 13 % Shoes 13 % 13 % 13 % 13 % Accessories, Lingerie, Fine Jewelry, and Fragrances 13 % 12 % 13 % 13 % Children's 7 % 8 % 8 % 8 % Total 100 % 100 % 100 % 100 % Cash Dividends. Dividends included in the Condensed Consolidated Statements of Cash Flows reflect cash dividends paid during the periods shown. Dividends per share reported on the Condensed Consolidated Statements of Earnings reflect cash dividends declared during the periods shown. The Company's Board of Directors declared cash dividends of $0.1175 per common share in February and May 2015, respectively, and $0.1000 per common share in February, May, August, and November 2014, respectively. In August 2015 , the Company's Board of Directors declared a cash dividend of $0.1175 per common share, payable on September 30, 2015 . Litigation, claims, and assessments. Like many retailers, the Company has been named in class action lawsuits, primarily in California, alleging violation of wage and hour laws and consumer protection laws. Class action litigation remains pending as of August 1, 2015 . The Company is also party to various other legal and regulatory proceedings arising in the normal course of business. Actions filed against the Company may include commercial, product and product safety, customer, intellectual property, and labor and employment-related claims, including lawsuits in which private plaintiffs or governmental agencies allege that the Company violated federal, state, and/or local laws. Actions against the Company are in various procedural stages. Many of these proceedings raise factual and legal issues and are subject to uncertainties. In the opinion of management, the resolution of pending class action litigation and other currently pending legal and regulatory proceedings will not have a material adverse effect on the Company’s financial condition, results of operations, or cash flows. Recently issued and adopted accounting standards. In April 2015, the FASB issued Accounting Standards Update 2015-03, Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03). The standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as an asset. ASU 2015-03 is effective for annual and interim reporting periods after December 15, 2015, with early adoption permitted. The Company early adopted ASU 2015-03 retrospectively in its first fiscal quarter ended May 2, 2015. As a result of the retrospective adoption, the Company reclassified unamortized debt issuance costs of $2.8 million and $0.3 million as of January 31, 2015 and August 2, 2014, respectively, from Other long-term assets to a reduction in Long-term debt on the condensed consolidated balance sheets. Adoption of this standard did not impact results of operations, retained earnings, or cash flows in the current or previous interim and annual reporting periods.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The carrying value of cash and cash equivalents, short- and long-term investments, restricted cash and cash equivalents, restricted investments, accounts receivable, other long-term assets, accounts payable, and other long-term liabilities approximates their estimated fair value. Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. The inputs used to measure fair value include: 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; and Level 3, unobservable inputs in which little or no market data exists. This fair value hierarchy requires the Company to develop its own assumptions and maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There were no transfers between Level 1 and Level 2 categories during the three and six month periods ended August 1, 2015 . The fair value of the Company’s financial instruments are as follows: ($000) August 1, 2015 January 31, 2015 August 2, 2014 Cash and cash equivalents Level 1 $ 630,288 $ 696,608 $ 549,784 Investments Level 2 3,612 3,610 3,660 Restricted cash and cash equivalents Level 1 $ 72,076 $ 71,992 $ 74,586 Restricted investments Level 1 $ 3,768 $ 3,828 $ 3,805 Level 2 — — 112 The underlying assets in the Company’s non-qualified deferred compensation program as of August 1, 2015 , January 31, 2015 , and August 2, 2014 (included in Other long-term assets and in Other long-term liabilities) primarily consist of participant-directed money market, stable value, stock, and bond funds. The fair value measurement for funds with quoted market prices in active markets (Level 1) and for funds without quoted market prices in active markets (Level 2) are as follows: ($000) August 1, 2015 January 31, 2015 August 2, 2014 Level 1 $ 82,953 $ 81,926 $ 79,753 Level 2 12,842 12,128 13,638 Total $ 95,795 $ 94,054 $ 93,391

The Company grants shares of restricted stock or restricted stock units to directors, officers, and key employees. The market value of shares of restricted stock and of the stock underlying restricted stock units at the date of grant is amortized to expense over the vesting period of generally three to five years. During the three and six month periods ended August 1, 2015 and August 2, 2014 , shares purchased by the Company for tax withholding totaled 33,705 and 1,206,903 and 62,544 and 1,031,252 , respectively, and are considered treasury shares which are available for reissuance. Performance shares. The Company has a performance share award program for senior executives. A performance share award represents a right to receive shares of restricted stock or restricted stock units on a specified settlement date based on the Company’s attainment of a profitability-based performance goal during the performance period, which is the Company’s fiscal year. If attained, the restricted stock or units then vest over a service period, generally two to three years from the date the performance award was granted. The release of shares related to restricted stock units earned are deferred generally for one year from the date earned. As of August 1, 2015 , shares related to unvested restricted stock and performance share awards totaled 6.0 million shares. A summary of restricted stock and performance share award activity for the six month period ended August 1, 2015 is presented below: (000, except per share data) Number of shares Weighted average grant date fair value Unvested at January 31, 2015 6,982 $ 24.01 Awarded 1,830 51.95 Released (2,480 ) 16.71 Forfeited (354 ) 29.43 Unvested at August 1, 2015 5,978 $ 33.61 The unamortized compensation expense at August 1, 2015 was $110.7 million which is expected to be recognized over a weighted-average remaining period of 2.1 years. The unamortized compensation expense at August 2, 2014 was $106.6 million , which was expected to be recognized over a weighted-average remaining period of 2.2 years. Employee stock purchase plan.

The purchase price of the stock is 85% of the closing market price on the date of purchase. Purchases occur on on the last trading day of each calendar quarter. The Company recognizes expense for ESPP purchase rights equal to the value of the 15% discount given on the purchase date. Stock option activity.

Earnings Per Share

Earnings Per Share	6 Months Ended
	Aug. 01, 2015
Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company computes and reports both basic earnings per share ("EPS") and diluted EPS. Basic EPS is computed by dividing net earnings by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net earnings by the sum of the weighted average number of common shares and dilutive common stock equivalents outstanding during the period. Diluted EPS reflects the total potential dilution that could occur from outstanding equity plan awards, including unexercised stock options, and unvested shares of both performance and non-performance based awards of restricted stock and restricted stock units. For the three and six month periods ended August 1, 2015 , approximately 2,100 and 2,900 weighted average shares, respectively, were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive for those periods presented. For the three and six month periods ended August 2, 2014 , approximately 22,400 and 12,300 weighted average shares, respectively, were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive for those periods presented. The following is a reconciliation of the number of shares (denominator) used in the basic and diluted EPS computations: Three Months Ended Six Months Ended Shares in (000s) Basic EPS Effect of dilutive common stock equivalents Diluted EPS Basic EPS Effect of dilutive common stock equivalents Diluted EPS August 1, 2015 Shares 404,760 2,933 407,693 406,211 3,351 409,562 Amount $ 0.64 $ (0.01 ) $ 0.63 $ 1.33 $ (0.01 ) $ 1.32 August 2, 2014 Shares 415,130 4,175 419,305 416,514 4,699 421,213 Amount $ 0.58 $ (0.01 ) $ 0.57 $ 1.16 $ (0.01 ) $ 1.15

Interest on the 2024 Notes is payable semi-annually. As of August 1, 2015 , the Company also had outstanding two other series of unsecured senior notes in the aggregate principal amount of $150 million , held by various institutional investors.

Income Tax Disclosure [Abstract]
Taxes On Earnings	Taxes on Earnings As of August 1, 2015 , January 31, 2015 , and August 2, 2014 , the reserves for unrecognized tax benefits were $105.2 million , $101.7 million , and $101.9 million inclusive of $20.8 million , $23.6 million , and $23.7 million of related interest and penalties, respectively. The Company accounts for interest and penalties related to unrecognized tax benefits as a part of its provision for taxes on earnings. If recognized, $51.8 million would impact the Company’s effective tax rate. The difference between the total amount of unrecognized tax benefits and the amounts that would impact the effective tax rate relates to amounts attributable to deferred income tax assets and liabilities. These amounts are net of federal and state income taxes. During the next twelve months, it is reasonably possible that the statute of limitations may lapse pertaining to positions taken by the Company in prior year tax returns. If this occurs, the total amount of unrecognized tax benefits may decrease, reducing the provision for taxes on earnings by up to $3.6 million . The Company is open to audit by the Internal Revenue Service under the statute of limitations for fiscal years 2011 through 2014 . The Company’s state income tax returns are generally open to audit under the various statutes of limitations for fiscal years 2010 through 2014 . Certain state tax returns are currently under audit by state tax authorities. The Company does not expect the results of these audits to have a material impact on the consolidated financial statements.

Accounting Policies [Abstract]
Basis of presentation	The accompanying unaudited interim condensed consolidated financial statements have been prepared from the records of Ross Stores, Inc. and subsidiaries (the “Company”) without audit and, in the opinion of management, include all adjustments (consisting of only normal, recurring adjustments) necessary to present fairly the Company’s financial position as of August 1, 2015 and August 2, 2014 , the results of operations and comprehensive income for the three and six month periods ended August 1, 2015 and August 2, 2014 , and cash flows for the six month periods ended August 1, 2015 and August 2, 2014 . The Condensed Consolidated Balance Sheet as of January 31, 2015 , presented herein, has been derived from the Company’s audited consolidated financial statements for the fiscal year then ended. Accounting policies followed by the Company are described in Note A to the audited consolidated financial statements for the fiscal year ended January 31, 2015 . Certain information and disclosures normally included in the notes to annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted for purposes of these interim condensed consolidated financial statements. The interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including notes thereto, contained in the Company’s Annual Report on Form 10-K for the year ended January 31, 2015 . The results of operations and comprehensive income for the three and six month periods ended August 1, 2015 and August 2, 2014 presented herein are not necessarily indicative of the results to be expected for the full fiscal year.
Restricted cash, cash equivalents and investments	The Company has restricted cash, cash equivalents, and investments that serve as collateral for certain insurance obligations of the Company. These restricted funds are invested in bank deposits, money market mutual funds, U.S. Government and agency securities, and corporate securities and cannot be withdrawn from the Company’s account without the prior written consent of the secured parties. The following table summarizes total restricted cash, cash equivalents, and investments which were included in Prepaid expenses and other and Other long-term assets in the Condensed Consolidated Balance Sheets as of August 1, 2015 , January 31, 2015 , and August 2, 2014 :
Property and equipment	As of August 1, 2015 and August 2, 2014 , the Company had $10.0 million and $22.6 million , respectively, of property and equipment purchased but not yet paid. These purchases are included in Property and Equipment, Accounts payable, and Accrued expenses and other in the accompanying Condensed Consolidated Balance Sheets.
Provision for litigation costs and other legal proceedings	Like many retailers, the Company has been named in class action lawsuits, primarily in California, alleging violation of wage and hour laws and consumer protection laws. Class action litigation remains pending as of August 1, 2015 . The Company is also party to various other legal and regulatory proceedings arising in the normal course of business. Actions filed against the Company may include commercial, product and product safety, customer, intellectual property, and labor and employment-related claims, including lawsuits in which private plaintiffs or governmental agencies allege that the Company violated federal, state, and/or local laws. Actions against the Company are in various procedural stages. Many of these proceedings raise factual and legal issues and are subject to uncertainties. In the opinion of management, the resolution of pending class action litigation and other currently pending legal and regulatory proceedings will not have a material adverse effect on the Company’s financial condition, results of operations, or cash flows.
Recently issued accounting standards	In April 2015, the FASB issued Accounting Standards Update 2015-03, Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03). The standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as an asset. ASU 2015-03 is effective for annual and interim reporting periods after December 15, 2015, with early adoption permitted. The Company early adopted ASU 2015-03 retrospectively in its first fiscal quarter ended May 2, 2015. As a result of the retrospective adoption, the Company reclassified unamortized debt issuance costs of $2.8 million and $0.3 million as of January 31, 2015 and August 2, 2014, respectively, from Other long-term assets to a reduction in Long-term debt on the condensed consolidated balance sheets. Adoption of this standard did not impact results of operations, retained earnings, or cash flows in the current or previous interim and annual reporting periods.
Taxes on Earnings	The Company accounts for interest and penalties related to unrecognized tax benefits as a part of its provision for taxes on earnings.
