There is no single standard truck bed: bed names and lengths vary by model. Ford lists 5.5-, 6.5- and 8-ft boxes for the full-size 2026 F-150, and Toyota lists 5- and 6-ft beds for the midsize 2026 Tacoma. The chart below shows those nominal sizes, with Ford’s inside floor lengths from its 2026 F-150 spec sheet and Toyota’s announced Tacoma bed lengths. Then: how to measure your own bed, what fits, and three tools that help.
Truck Bed Sizes Chart
| Bed size (common name) | Rough length | Maker spec | Example model |
|---|---|---|---|
| Midsize short bed | About 5 ft | Toyota: 5-ft bed | 2026 Toyota Tacoma |
| Midsize long bed | About 6 ft | Toyota: 6-ft bed | 2026 Toyota Tacoma |
| Full-size short bed | About 5.5 ft | Ford: 5.5-ft box, 67.1 in inside | 2026 Ford F-150 |
| Full-size standard bed | About 6.5 ft | Ford: 6.5-ft box, 78.9 in inside | 2026 Ford F-150 |
| Full-size long bed | About 8 ft | Ford: 8-ft box, 97.6 in inside | 2026 Ford F-150 |
The names are rounded, so always check the inside numbers for your exact truck: year, cab style and bed. Ford, for example, calls its shortest F-150 bed the 5.5-ft box, but the inside floor length is 67.1 inches.
Truck Bed Dimensions: 2026 Ford F-150 Example
Ford’s 2026 F-150 specifications list three boxes with these inside cargo dimensions:
| 2026 Ford F-150 (Ford spec sheet) | 5.5-ft box | 6.5-ft box | 8-ft box |
|---|---|---|---|
| Inside length at floor | 67.1 in (67.2 Raptor) | 78.9 in | 97.6 in |
| Width between wheelhouses | 50.6 in | 50.6 in | 50.6 in |
| Inside height (at molding) | 21.4 in | 21.4 in | 21.4 in |
| Cargo box volume | 52.8 cu ft | 62.3 cu ft | 77.4 cu ft |
The width between the wheelhouses (50.6 in) is the narrowest point of the floor, which is why it matters for flat loads like a 4 ft wide sheet of plywood. Toyota’s 2026 Tacoma announcement lists bed lengths of 5 or 6 feet for the midsize Tacoma; check Toyota’s spec sheet for the inside numbers.
How Long Is a Standard Truck Bed?
On a truck offered with three box lengths, like the F-150, “standard bed” usually refers to the middle option: Ford lists the 2026 F-150’s 6.5-ft box at 78.9 inches inside at the floor. Toyota announces 5- and 6-ft beds for the 2026 Tacoma. Compare each configuration’s overall length and cargo dimensions before choosing.

How to Measure Your Truck Bed
- Length: close the tailgate and measure along the floor from the inside of the bulkhead (front wall) to the inside of the tailgate.
- Width between the wheel wells: measure the narrowest point across the floor.
- Usable width: measure ahead of, between and behind the wheel wells at the height where your load or accessory will sit, and note any liner or other obstruction.
- Height: measure from the floor to the top of the bed rail.
- For accessories: note your year, cab style and the maker’s bed name too. Accessory listings can name the same bed differently (one F-150 bed liner listing calls the 5.5-ft box a 5’7″ bed), so match by truck year, cab and bed, not only by your tape number. For tonneau covers, use our tonneau cover measuring guide.
What Fits in Each Bed Size?
- 4×8 plywood or drywall flat on the floor: a nominal 48 x 96 in sheet needs at least 96 in of usable floor length and 48 in of clear width to lie flat with the tailgate closed. The listed F-150 8-ft box dimensions (97.6 in, 50.6 in) meet those numbers; in a shorter bed the sheet extends past the closed-tailgate position, so support and secure it properly.
- Bikes, coolers and camping gear: measure them against the bed’s usable dimensions. A correctly fitted cargo bar can help limit movement; secure the load following the truck and restraint makers’ instructions.
- Long items (lumber, ladders, kayaks): choose a setup that supports and secures the item. If you use a lowered tailgate or a bed extender, follow its instructions and load limits, and check local overhang and marking rules.
- Truck bed tents and toolboxes are sold by bed size, so measure first. See our truck bed tent and truck bed tool box guides.

Black Friday Tip and Gift Idea
Black Friday tip: before deals on bed covers, liners, mats or tents start, write down your truck’s year, cab style and the maker’s bed name (for example “6.5-ft box”), plus your own tape measurements. On the day, check the deal is for that exact fit before you compare offers.
Gift idea: bed-size accessories make useful gifts for truck owners, but confirm the year, cab and bed first; a tape measure is an option when you don’t know the fit, while a cargo bar still needs the installation width checked.
Frequently Asked Questions
How long is a standard truck bed?
There’s no single standard; bed names and lengths vary by model. Ford lists 5.5-, 6.5- and 8-ft boxes for the 2026 F-150, with the middle 6.5-ft box at 78.9 inches inside at the floor, and Toyota lists 5- and 6-ft beds for the 2026 Tacoma. Check the spec sheet for your truck’s year, cab and bed.
What are the dimensions of a full-size truck bed?
Using the 2026 Ford F-150 as an example, Ford lists inside floor lengths of 67.1 inches for the 5.5-ft box (67.2 inches for Raptor), 78.9 inches for the 6.5-ft box and 97.6 inches for the 8-ft box. All three list 50.6 inches between the wheelhouses and 21.4 inches inside height at the molding. Other trucks differ, so check your model’s spec sheet.
Will a 4×8 sheet of plywood fit in a truck bed?
A nominal 48 x 96 in sheet needs at least 96 inches of usable floor length and 48 inches of clear width to lie flat with the tailgate closed. The listed 2026 F-150 8-ft box dimensions (97.6 in long, 50.6 in between wheelhouses) meet those numbers. In a shorter bed, the sheet extends past the closed-tailgate position, so make sure it’s properly supported and secured; any overhang marking your local rules require is in addition to that.
Why do accessory listings call my bed a different size?
Bed names are rounded. Ford calls the shortest F-150 box the 5.5-ft box, but its inside floor length is 67.1 inches (about 5 ft 7 in), and some accessory listings call it a 5’7″ bed. Match accessories by the truck’s year, cab and the maker’s bed name, not by your own rounded number.
How do I measure my truck bed?
With the tailgate closed, measure the floor from the inside of the bulkhead (front wall) to the inside of the tailgate. Then measure the width between the wheel wells and at the widest point, and the height from the floor to the top of the bed rail. For a tonneau cover, follow our tonneau cover measuring guide.
Short bed or long bed: which should I get?
A longer bed gives more floor length, but the truck’s overall length also depends on the cab and configuration. Compare usable bed dimensions, overall vehicle length and your parking space with the items you regularly carry.
