Tundra bed size — frequently asked
What bed sizes does the Toyota Tundra come in?
The Toyota Tundra has been offered with 5 bed lengths: 5.5 ft (66.7"), 6.5 ft (78.7"), 8.1 ft (97.6"), 6.2 ft (74.7") and 8 ft (98.2"). The exact bed on your truck depends on its model year and cab — choose your year above to see which covers fit.
How do I measure my Tundra bed length?
Measure the inside floor of the bed, from the bulkhead (the wall behind the cab) to the inside of the closed tailgate. Round to the nearest standard size — tonneau covers are sold by bed-length category (e.g. 5.5 ft, 6.5 ft, 8 ft), not the exact inch.
What bed size is the newest Tundra?
The current Tundra (2022–present) comes with 5.5 ft (66.7"), 6.5 ft (78.7") and 8.1 ft (97.6").
Will a tonneau cover from an older Tundra fit a newer one?
Not necessarily. Covers are matched to a specific generation and bed length, and both the bed length and the rail design can change between generations. Always match your exact model year and bed size before buying — the year-by-year table below shows where the Tundra changed.
