Sources are linked in the tool result for each generation. Heavy-duty trucks we couldn't source from a maker document (Ford Super Duty 2017–2022, GM 2500HD/3500HD) and the Nissan Titan are left out rather than guessed.

Nominal bed sizes vs real inches

Cover listings use rounded names that don't always match the truck maker's. Ford calls its short box "5.5-ft" and publishes 67.1 in at the floor; BAK, Gator and others list the same bed as 5'7". Ram's "5'7\"" box is 67.4 in. GM's 2019-and-later short bed measures 69.9 in at the floor and cover makers list it as 5'10"; the 2014–2018 short bed is 69.3 in and shows up as 5'8" or 5'9" on cover listings. None of that matters as long as you buy the cover listed for your generation and bed name; it does matter if you're measuring a used truck and guessing its configuration. Measure the floor from the bulkhead to the inside of the closed tailgate and match the nearest size listed for your truck.

What changes the part number besides length

  • Ram 1500: RamBox cargo bins and the Multi-Function (split) tailgate each have their own cover versions.
  • Silverado and Sierra: the CarbonPro composite bed and some MultiPro/MultiFlex tailgates need specific parts.
  • Toyota Tacoma and Tundra: the factory deck rail system and Trail Special Edition storage boxes change fitment.
  • Every truck: over-the-rail bed liners, aftermarket bed rails and toolboxes can block the clamps.

A worked example

A 2023 F-150 SuperCrew with the short box: choose Ford, F-150, 2021–2026 and SuperCrew 5.5-ft box. The finder shows 67.1 in (5 ft 7.1 in) from Ford's spec sheet and lists the cover listings we checked for that bed, such as the BAKFlip MX4 (part 448339) and the Gator soft roll-up. Then open the bed access calculator from the result to see how much of those 67 inches each cover type leaves open. If you're still choosing a cover type, try the cover matcher, or read the best tonneau covers for the F-150.

Frequently asked questions

How do I measure my truck bed for a tonneau cover?
Measure along the bed floor from the inside of the front bulkhead to the inside of the closed tailgate. Covers are sold by nominal sizes such as 5.5 ft, 5'7", 6.5 ft and 8 ft, so round to the nearest one listed for your truck generation, then confirm with the listing's fitment tool.
Is the F-150 5.5 ft bed the same as 5'7"?
Yes. Ford calls it the 5.5-ft box; its spec sheet gives 67.1 in inside length at the floor, which many cover makers list as 5'7". The same happens with Ram's 5'7" bed (67.4 in) and GM's short bed, which cover makers list as 5'8", 5'9" or 5'10" depending on generation.
Why does my cover need to match the model year and not just the bed length?
Bed rails, tailgates, stake pockets and bed-wall shapes change between generations, and covers clamp to those exact shapes. A 2019+ Silverado short bed and a 2014–2018 one are close in length but take different cover part numbers. Factory options such as Ram's RamBox and multi-function tailgate, GM's CarbonPro bed and Toyota's deck rails change the part number too.
Where do these bed lengths come from?
Each figure comes from the truck maker's own spec sheet, brochure or official specification page, linked under the result. Makers measure slightly differently (Ford, GM and Toyota publish inside length at the floor; Ram publishes length at the floor with the tailgate closed), so small differences between brands are normal.
