What are the dimensions of a Ford F-150 truck bed?
The Ford F-150 offers three primary bed lengths—5.5 feet, 6.5 feet, and 8 feet—with a consistent internal width around 50 inches between the wheel wells and side walls about 21 inches tall. Availability of each bed length varies by cab configuration and model year.
Bed length options
The bed length you get depends on the cab style and trim level. Here are the standard dimensions you’ll typically encounter.
- 5.5-foot bed — 67.1 inches long; internal width between wheel wells about 50.0 inches; bed depth (side-wall height) roughly 21.0–21.5 inches. Common on Regular Cab and some two-door configurations.
- 6.5-foot bed — 78.7 inches long; internal width about 50.0 inches; bed depth around 21.0–21.5 inches. Widely paired with SuperCrew and SuperCab cabs.
- 8-foot bed — 96.0 inches long; internal width about 50.0 inches; bed depth around 21.0–21.5 inches. Typically available on certain Regular Cab configurations and selected trims.
These are the standard bed-length options offered on most current F-150 configurations. Exact availability depends on year, cab type, and trim level. Always confirm with the dealer or build sheet for a specific truck.
Key internal dimensions and cargo footprint
Beyond length, the bed’s usable space is defined by its width between wheel wells and its height. The following figures reflect typical values that apply across common bed lengths, though exact numbers can shift by configuration.
Internal width between wheel wells
Dimensions to know how wide items can sit in the bed without obstruction.
- Internal width between wheel wells: about 50.0 inches.
Understanding this width helps in planning larger items and how they will fit crosswise in the bed.
Bed side height (depth)
How tall the bed walls are from the floor to the top edge affects vertical clearance for loads and accessories.
- Bed side height: approximately 21.0–21.5 inches.
Keep in mind that spray-in bedliners, rails, or accessories can slightly modify usable height and space.
Cargo volume by bed length
Rough estimates of how much cargo space each bed length provides, useful for planning payload and storage needs.
- 5.5-foot bed: about 52 cubic feet of cargo volume.
- 6.5-foot bed: about 62 cubic feet of cargo volume.
- 8-foot bed: about 76 cubic feet of cargo volume.
These volume figures illustrate how longer beds translate to more flat-floor space, though actual usable space can vary with tailgate configurations and bed features.
Choosing the right bed for your needs
Selecting the appropriate bed length hinges on your typical loads, towing requirements, and whether you prioritize maximum flat cargo space or maneuverability. The 8-foot bed offers the most space for long items, while the 5.5-foot bed is easier to park and handle in tight spaces. The 6.5-foot bed often serves as a balanced option for mixed daily use. Always verify exact bed availability for your desired year, trim, and cab configuration.
Summary
The Ford F-150 provides three main bed lengths—5.5 ft, 6.5 ft, and 8 ft—with an internal width around 50 inches and side-wall height near 21 inches. Availability varies by year and cab configuration, so check the specific build for precise numbers. For practical planning, expect roughly 52–76 cubic feet of cargo space depending on bed length.
