Accounting Policies [Abstract]
Basis of presentation	Basis of Presentation The condensed consolidated financial statements include the accounts of Logitech and its subsidiaries. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and therefore do not include all the information required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended March 31, 2023, included in its Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on May 17, 2023. In the opinion of management, these condensed consolidated financial statements include all adjustments, consisting of only normal and recurring adjustments, necessary and in all material aspects, for a fair statement of the results of operations, comprehensive income, financial position, cash flows and changes in shareholders' equity for the periods presented. Operating results for the three months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2024, or any future periods.
Changes in Significant Accounting Policies	Changes in Significant Accounting Policies There have been no material changes in the Company’s significant accounting policies during the three months ended June 30, 2023 compared with the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended March 31, 2023.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Significant estimates and assumptions made by management involve the fair value of goodwill and intangible assets acquired from business acquisitions, contingent consideration for a business acquisition and periodic reassessment of its fair value, valuation of investment in privately held companies classified under Level 3 fair value hierarchy, pension obligations, accruals for customer incentives, cooperative marketing, and pricing programs and related breakage when appropriate, inventory valuation, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results could differ materially from those estimates.
Risks and Uncertainties	Risks and Uncertainties Impacts of Macroeconomic and Geopolitical Conditions on the Company's Business The Company's business has been impacted by adverse macroeconomic and geopolitical conditions. These conditions include inflation, interest rate and foreign currency fluctuations, slowdown of economic activity around the world, and lower consumer and enterprise spending. In addition, the war in Ukraine resulted in global supply chain, logistics, and inflationary challenges. The Company has had no revenue in Russia and Ukraine since fiscal year 2023 as it has indefinitely ceased all sales and shipments to Russia and sales in Ukraine have also been halted due to the ongoing military operations on the Ukrainian territory. The global and regional economic and political conditions adversely affect demand for the Company's products. These conditions also had an impact on the Company's suppliers, contract manufacturers, logistics providers, and distributors, causing volatility in cost of materials and shipping and transportation rates, and as a result impacting the pricing of the Company's products.
