What size is your truck bed, really?
A "5.5 ft bed" is almost never 66.0 inches. Pick your truck and get the actual length, width, and space between the wheelhouses — then the exact tonneau cover size class to buy.

Why actual inches matter
Tonneau covers, bed mats, liners, and toolboxes are built to real dimensions, not marketing names. Two trucks both sold as "short bed" can differ by more than an inch in length and by several inches between the wheelhouses — enough for a cover that won't clamp, or a sheet of plywood that won't lie flat. Every figure on this site comes from the manufacturer's published specifications, with the source and the date we checked it on the page. Measure your own bed in two minutes to confirm before you buy.
