Accounting Policies [Abstract]
Basis of Presentation [Text Block]	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Publix Super Markets, Inc. and subsidiaries (Company) 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 six months ended June 25, 2022 are not necessarily indicative of the results for the entire 2022 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 25, 2021. 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. On April 1, 2022, the Company filed Articles of Amendment to its Restated Articles of Incorporation in order to effect a 5-for-1 stock split of the Company’s common stock, par value $1.00 per share (Common Stock), and an increase in the number of authorized shares of Common Stock from 1,000,000,000 to 4,000,000,000, effective as of the close of business April 14, 2022. The Articles of Amendment were approved by the Company’s Board of Directors on April 1, 2022. All applicable data, including share and per share amounts, in the condensed consolidated financial statements and accompanying notes have been retroactively adjusted to give effect to the stock split.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments [Text Block]	Fair Value of Financial Instruments The fair value of certain of the Company’s financial instruments, including cash and cash equivalents, trade receivables and accounts payable, approximates their respective carrying amounts due to their short-term maturity. The fair value of investments is based on market prices using the following measurement categories: Level 1 – Fair value is determined by using quoted prices in active markets for identical investments. Investments included in this category are equity securities (exchange traded funds). Level 2 – Fair value is determined by using other than quoted prices. By using observable inputs (for example, benchmark yields, interest rates, reported trades and broker dealer quotes), the fair value is determined through processes such as benchmark curves, benchmarking of similar securities and matrix pricing of corporate, government-sponsored agency, state and municipal bonds by using pricing of similar bonds based on coupons, ratings and maturities. Investments included in this category are primarily debt securities (tax exempt and taxable bonds), including restricted investments in taxable bonds held as collateral. Level 3 – Fair value is determined by using other than observable inputs. Fair value is determined by using the best information available in the circumstances and requires significant management judgment or estimation. No investments are currently included in this category. Following is a summary of fair value measurements for investments as of June 25, 2022 and December 25, 2021: Fair Value Level 1 Level 2 Level 3 (Amounts are in thousands) June 25, 2022 $ 12,349,086 2,175,635 10,173,451 — December 25, 2021 13,651,477 2,159,365 11,492,112 —

Consolidation Of Joint Ventures And Long Term Debt [Abstract]
Consolidation Of Joint Ventures And Long-Term Debt [Text Block]	Consolidation of Joint Ventures and Long-Term Debt From time to time, the Company enters into a joint venture (JV), in the legal form of a limited liability company, with certain real estate developers to partner in the development of a shopping center with the Company as the anchor tenant. The Company consolidates certain of these JVs in which it has a controlling financial interest. As of June 25, 2022, the carrying amounts of the assets and liabilities of the consolidated JVs were $182,630,000 and $75,386,000, respectively. As of December 25, 2021, the carrying amounts of the assets and liabilities of the consolidated JVs were $194,493,000 and $76,027,000, respectively. The assets are owned by and the liabilities are obligations of the JVs, not the Company, except for a portion of the long-term debt of certain JVs guaranteed by the Company. The JVs are financed with capital contributions from the members, loans and/or the cash flows generated by the JV owned shopping centers once in operation. Total earnings attributable to noncontrolling interests for 2022 and 2021 were immaterial. The Company’s involvement with these JVs does not have a significant effect on the Company’s financial condition, results of operations or cash flows. The Company’s long-term debt results primarily from the consolidation of loans of certain JVs and loans assumed in connection with the acquisition of certain shopping centers with the Company as the anchor tenant. No loans were assumed during the six months ended June 25, 2022 or June 26, 2021. Maturities of JV loans range from January 2023 through April 2027 and have variable interest rates based on a London Interbank Offered Rate (LIBOR) index or Secured Overnight Financing Rate (SOFR) index plus 200 to 250 basis points. Maturities of assumed shopping center loans range from November 2022 through January 2027 and have fixed interest rates ranging from 3.7% to 7.5%.

Retirement Plan [Text Block]	Retirement PlanThe Company has a trusteed, noncontributory Employee Stock Ownership Plan (ESOP) for the benefit of eligible employees. Since the Company’s common stock is not traded on an established securities market, the ESOP includes a put option for shares of the Company’s common stock distributed from the ESOP. Shares are distributed from the ESOP primarily to separated vested participants and certain eligible participants who elect to diversify their account balances. Under the Company’s administration of the ESOP’s put option, if the owners of distributed shares desire to sell their shares, the Company is required to purchase the shares at fair value for a specified time period after distribution of the shares from the ESOP. The fair value of distributed shares subject to the put option totaled $775,113,000 and $608,089,000 as of June 25, 2022 and December 25, 2021, respectively. The cost of the shares held by the ESOP totaled $3,476,762,000 and $3,217,039,000 as of June 25, 2022 and December 25, 2021, respectively. Due to the Company’s obligation under the put option, the distributed shares subject to the put option and the shares held by the ESOP are classified as temporary equity in the mezzanine section of the condensed consolidated balance sheets and totaled $4,251,875,000 and $3,825,128,000 as of June 25, 2022 and December 25, 2021, respectively. The fair value of the shares held by the ESOP totaled $11,869,270,000 and $10,855,152,000 as of June 25, 2022 and December 25, 2021, respectively.

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 six months ended June 25, 2022 are not necessarily indicative of the results for the entire 2022 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 25, 2021. 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.
