How big is the bed of a Ford 6 3 4?

There isn’t a Ford bed size officially labeled “6 3 4.” Ford pickups offer bed lengths measured in feet and inches, with the most common options being 5.5 ft, 6.5 ft, and 8 ft for the F-150, and 6.75 ft or 8 ft for the Super Duty line. To identify the exact size, you’ll need the specific model year and cab configuration.


What the question might mean


The phrase could refer to a misremembered “6'4” bed” or simply to a nonstandard reading of bed length. Ford’s current lineup standardizes bed lengths in whole-foot-plus-inch measurements, and the exact option varies by generation, trim, and cab style. The following sections summarize the official, widely available bed lengths you’re likely to encounter.


Ford F-150 bed sizes


The F-150 is offered with three bed lengths in most recent generations. The figures below reflect the common options across regular, extended, and crew cab configurations.



  • 5.5 ft bed — 66 inches long

  • 6.5 ft bed — 78 inches long

  • 8 ft bed — 96 inches long


These are the standard choices you’ll see advertised for the F-150, though availability can vary by year, cab style, and trim.


Ford Super Duty bed sizes


The heavy‑duty F-250/350 series offers a different set of bed lengths aimed at builders and haulers. The typical options are:



  • 6.75 ft bed — 81 inches long

  • 8 ft bed — 96 inches long


As with the lighter F-150, actual availability depends on the exact model year, cab configuration, and package.


Is there a 6'4" bed?


Ford does not currently publish a factory option listed as 6'4" (76 inches) for modern F-Series pickups. The closest standard measurements are 6.5 ft (78 inches) and 6.75 ft (81 inches). If you’ve seen a reference to 6'4" in advertisements or a listing, it may be a rounding/typing variant or pertain to a discontinued or special-order configuration. Always verify with the dealer or the official window sticker for your exact vehicle.


How to verify bed size for your vehicle


To confirm the bed length for a specific Ford truck you’re curious about, you can use several reliable checks:



  • Review the window sticker or the vehicle’s build sheet provided at purchase.

  • Check the owner’s manual or a Ford official spec sheet for the exact model year.

  • Physically measure the bed: measure the interior length from the tailgate to the front wall of the bed, and the interior width between the side walls at the floor.


Verifying this information helps ensure you’re comparing the right bed size for the exact configuration you’re considering.


Practical considerations


Bed length influences cargo capacity, payload, and garage fit. A longer bed offers more floor space for equipment and materials, but can reduce maneuverability in tight garages and decrease fuel efficiency slightly. Cab choice (Regular, SuperCab, or SuperCrew) often determines which bed lengths are available for a given model year.


Summary


In short, there is no official “Ford 6 3 4” bed size. For the Ford F-150, standard bed lengths are 5.5 ft, 6.5 ft, and 8 ft; for the Super Duty line, 6.75 ft and 8 ft are typical. If you’re seeking a 6'4" bed specifically, it isn’t a current standard option and you should verify the exact size with a dealer or by checking the vehicle’s official documentation. Knowing the exact model year and cab configuration is essential to identifying the correct bed length.
