Accounting Policies [Abstract]
Basis of Presentation [Policy Text Block]	Basis of Presentation The condensed consolidated financial statements of Publix Super Markets, Inc. and subsidiaries (Company) and the accompanying notes are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial reporting. Accordingly, the accompanying statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, these statements include all adjustments that are of a normal and recurring nature necessary to present fairly the Company’s financial position and results of operations. Due to the seasonal nature of the Company’s business, the results of operations for the three and nine months ended September 27, 2025 may not necessarily be indicative of the results for the entire 2025 fiscal year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 28, 2024 (Annual Report). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
