Truck Bed Sizing
Bed Sizing:
These are a good rule of thumb for full-size trucks. Mid-size trucks might need something even narrower, shorter, or with a unique frame width or headache rack height, which can be available via special order.
Bed Widths:
- Single Rear Wheel Trucks take a 7’ or 84” wide bed
- Dual rear wheel trucks take an 8’ or 96” wide bed
- Brand to Brand can vary a few inches
- Some cab & chassis dually trucks take a slightly narrower bed, 90”-94”
Bed Lengths:
- Short bed trucks (6’6” approximate factory bed size), take a 7’ or 84” long bed
- Long bed trucks (with an 8’ approximate factory bed size, excludes cab & chassis), take an 8’6” or 102” long bed
- Cab & Chassis trucks (came from the factory as a cab & chassis, not a box delete). Depending on the cab to axle measurement beds are 9’4”, 11’4”, or even longer on some trucks. See next section for sizing
Cab to Axle Measurements:
- ALWAYS get a measurement, it is better to spend more time up front, than to get a wrong bed!
- Especially important if you are doing a skirted bed, the wheel-well in the bed directly corresponds to the cab to axle measurement!
- 38”: Short bed Dodge/Ram, Nissan, or Toyota
Corresponds to a 7’ bed length - 40”: Short bed Ford
