A truck bed is more than a box on wheels. It decides what you can haul, what fits, and which tonneau cover, bedliner or tool box you can buy. One wrong inch can ruin the fit.
This guide gives you a clear truck bed size chart, real truck bed width numbers, and a simple way to measure your own bed. All figures are in inches and use 2026 model-year specs where available.

Standard Truck Bed Sizes by Class and Length
What are the standard truck bed sizes? Most full-size pickups come in three bed lengths:
- Short bed: about 5.5 ft (roughly 66–70 in.)
- Standard bed: about 6.5 ft (roughly 76–80 in.)
- Long bed: about 8 ft (roughly 96–98 in.)
Mid-size trucks run shorter. Their beds are usually about 5 ft or 6 ft long.
Why do the numbers not match the name? Brands round up. A “5.5 ft” Ford F-150 box measures 66 inches at the floor. That is 5.5 ft, but only if you measure inside the box.
Also watch for inside versus outside box length. Outside numbers include the bed walls and run a few inches longer.
Which cabs pair with which beds? Crew cabs usually get the short or standard bed. Regular cabs are the most likely to offer the 8 ft long bed. The 2026 Silverado 1500 lineup shows this well. The short bed comes only on the crew cab, and the long bed only on the regular cab.
Truck Bed Dimensions Chart by Make and Model
Here is a quick truck bed size chart for popular full-size pickups.
| Truck (2026) | Bed | Length at floor | Width between wheel wells | Depth | Cargo volume |
|---|---|---|---|---|---|
| Ram 1500 | 5’7″ | 67.4 in. | 51 in. | 21.4 in. | 53.9 cu ft |
| Ram 1500 | 6’4″ | 76.3 in. | 51 in. | 21.5 in. | 61.5 cu ft |
| Ford F-150 | 5.5 ft | 66 in. | 50.6 in. | 21.4 in. | 52.8 cu ft |
| Ford F-150 | 6.5 ft | 78 in. | 50.6 in. | 21.4 in. | 62.3 cu ft |
| Chevy Silverado 1500 | Standard | 79.44 in. | 50.63 in. | 22.4 in. | n/a |
| Chevy Silverado 1500 | Long | 98.18 in. | 50.63 in. | 22.4 in. | n/a |
| Toyota Tundra | Short / Standard / Long | 65.6 / 77.6 / 96.5 in. | 48.7 in. | n/a | n/a |
The Silverado’s short bed runs about 69.92 inches. Heavy-duty trucks skip the short bed. Their standard bed is about 82 in., and the long bed is about 98 in.
Figures vary by model year, cab and trim. Older trucks differ, so check your own year before you buy parts.
Choosing the right truck bed size is only part of planning an efficient hauling or storage setup; the mounting hardware and support channels matter, too. Understanding Unistrut channel sizes and specifications can help you select the right components for building secure storage racks, organizing tools, or supporting custom truck bed accessories.
Truck Bed Width, Wheel Well Gap and Cargo Volume
How wide is a truck bed? Look at three numbers:
- Width at the rails: the widest point, near the top of the walls.
- Width at the floor: often the same on modern trucks.
- Width between the wheel wells: the narrowest gap, and the one that matters most.
Will a 4×8 sheet of plywood lie flat? A plywood sheet is 48 inches wide. It lies flat on a full-size bed with 50–51 inches between the wells. It will not lie flat on a mid-size truck. The 2026 Tacoma has only 44.7 inches.
How do you find cargo volume? Multiply length x width x depth in inches, then divide by 1,728 to get cubic feet. Try the Ram 1500 5’7″ bed:
67.4 x 66.4 x 21.4 = 95,773, and 95,773 / 1,728 = about 55.4 cu ft.
That is higher than Ram’s 53.9 cu ft. The wheel wells take up space the simple math ignores. Use the maker’s figure for real-world planning.
How to Measure a Truck Bed Correctly
Use a tape measure of 10 ft or longer. Keep the bed empty.
- Length: Close the tailgate. Measure along the floor, from the inside of the front wall to the inside of the tailgate.
- Width: Measure wall to wall at the floor.
- Wheel well gap: Measure the narrowest point between the two humps.
- Depth: Measure from the floor straight up to the top of the rail.
How do you measure a truck bed for a tonneau cover? Use your own length number. A 1-inch error can leave gaps or stop the cover from latching. Also note any rail caps or a spray-in liner, since they add thickness.
How do you measure for a tool box? Check the inside length and the wheel well gap. Also check the lid clearance behind the cab. If you tow a fifth wheel, leave extra room for the hitch.
Common mistakes:
- Measuring over the rails instead of inside the bed.
- Trusting a spec sheet alone.
- Ignoring the model year.
Confirm your numbers against your window sticker or build sheet before you order.

Know your bed before you buy. Measure it, match it to your model year, and check the wheel well gap. That small habit saves money and returns.
Conclusion
Choosing the right truck bed size helps you haul cargo safely and find the perfect tonneau cover, bedliner, or tool box. Always check the bed length, width, wheel well gap, and depth before buying accessories. Since dimensions vary by make, model, and year, measure your truck bed carefully. A few simple measurements can save you money, time, and unnecessary returns.
