Three different cab options and bed sizes will determine your Ford F-150 pickup truck's overall length. The shortest cab is the Regular Cab, which produces a Ford F-150 length of approximately 227 inches. Extend to the Ford SuperCab, and you'll add two back doors to the cabin. This configuration can push your truck's length to over 250 inches or so. Lastly, the Ford SuperCrew Cab provides the maximum amount of room possible for passengers. Two bed lengths are available with this cab that extend the overall length of approximately 231 and 243 inches.
