Compare All Three Ford F-150 Bed Dimensions
Truck shoppers usually talk bed size in feet. Ford, on the other hand, talks in inches, and the gap between the two is where most of the confusion starts. A “6.5-foot” box isn’t exactly 78 inches on the nose, and the width that actually matters for loading drywall isn’t the one most people measure from the outside rails. Here are the real F-150 bed dimensions pulled directly from Ford’s spec sheet, along with what each box is actually like to live with on a daily basis.
The Baseline: Width and Depth
Every box shares the exact same 50.6 inches between the wheelhouses and 21.4 inches of inside height at the molding. Length is the only real variable here, which makes deciding between them a straightforward matter of prioritizing cargo space versus passenger room.
| Bed Size | Inside Length (Floor) | Cargo Volume | Available Cab Pairings |
|---|---|---|---|
| 5.5-foot | 67.1 in. | 52.8 cu. ft. | SuperCrew |
| 6.5-foot | 78.9 in. | 62.3 cu. ft. | Regular Cab, SuperCab, SuperCrew |
| 8-foot | 97.6 in. | 77.4 cu. ft. | Regular Cab |
5.5 Feet: Short Box, Big Cab
This is the shortest box paired with the longest cab. The 5.5-foot bed comes exclusively with the SuperCrew, measuring 67.1 inches at the floor and offering 52.8 cubic feet of cargo volume.
Here’s what often gets overlooked: A SuperCrew with this box runs 232.0 inches bumper to bumper, identical to a SuperCab with the 6.5-foot bed. You give up about a foot of cargo floor to gain four full-size doors and 43.6 inches of rear legroom, without adding a single inch of overall length to squeeze into the garage. For a family truck that still handles Saturday morning dump runs, it’s an easy call.
The 6.5-Foot Standard Box
This is the only box Ford offers on every single cab configuration: Regular, SuperCab, and SuperCrew alike, which is why many buyers just call it the standard bed. Floor length is 78.9 inches, and volume climbs to 62.3 cubic feet.
Opting for this bed on the SuperCrew stretches the truck’s overall length to 243.8 inches. It takes a bit more effort to park, but the longer wheelbase gives you a steadier ride with a trailer hooked up. Lumberyard runs work flawlessly; just drop the tailgate and flag the overhang.
Eight Feet of Floor
Want the true long bed? You’re getting a Regular Cab, full stop. The 8-foot box pairs solely with the three-seat cab by design, because the package is aimed squarely at the jobsite rather than the school pickup line.
You get 97.6 inches of floor space and 77.4 cubic feet of volume, the most of any F-150. A 4×8 sheet of plywood lies completely flat between the wheelhouses with the tailgate shut, and for many contractors, that’s the whole ballgame. Overall length actually lands at 228.1 inches, shorter than either SuperCrew, making it surprisingly easier to park than its bulky reputation suggests.
Beyond the Box: Real-World Fit
Spec sheets are great, but a tape measure is better. Here’s how a few everyday loads and specs shake out against the real numbers:
- 8-foot lumber in the 6.5-foot box: Tailgate down, roughly 17 inches hangs past the end of the floor.
- 8-foot lumber in the 8-foot box: Fully inside, with about an inch and a half to spare before the tailgate hits.
- 4×8 plywood in the 5.5-foot box: Flat between the wheelhouses, with about 29 inches resting on the dropped tailgate.
- Open tailgate to ground: Roughly 32.7 to 37.8 inches, depending heavily on configuration.
- Maximum payload: Up to 2,440 pounds when properly equipped.
Frequently Asked Questions
Q: Does the SuperCrew come with an 8-foot bed?
A: No. SuperCrew buyers pick between the 5.5- and 6.5-foot boxes. Eight feet of floor means a Regular Cab. Older buyer guides sometimes list outdated pairings, so confirm against the current order sheet before finalizing a build.
Q: Will an F-150 fit in a standard 20-foot garage?
A: It depends on the box. Twenty feet is 240 inches. Both Regular Cab versions, the SuperCab, and the SuperCrew with the 5.5-foot bed all clear that mark on paper. The SuperCrew with the 6.5-foot bed runs 243.8 inches. Measure your door to the back wall before signing any paperwork.
Q: How do I accurately measure my current bed?
A: Measure inside along the floor, from the front wall of the box directly to the closed tailgate. That’s the measurement behind Ford’s figures, explaining why a “6.5-foot” box actually reads 78.9 inches instead of an even 78.
