Chevrolet Colorado bed size & length
Every Colorado bed length in inches, generation by generation, from 2005–2026 — which cab each one comes with, and the tonneau cover size it takes.

one bed offered
Lengths are the inside floor measurement for the generation shown. Brochure names round hard — always measure your own bed before ordering a cover.
Colorado bed size by year
The bed line-up moved during this model's run, so the year matters more than the badge. Find your generation below.

What cover size a Colorado takes
Tonneau covers are sold by bed category, not by exact inches. Here is where each Colorado bed lands — and every other truck in the same category, in case you are cross-shopping a used cover.
Measuring a Colorado bed properly
Two minutes with a tape beats any chart, including this one. Covers are cut to the inside of the bed, so that is what has to be measured.
- 1
Close the tailgate
Measure with the tailgate up and latched. A bed measured with the gate down reads roughly 20 inches long and every cover ordered off that number comes back.
- 2
Measure inside, along the floor
Run the tape on the bed floor from the front bulkhead to the inside face of the closed tailgate. Not along the top of the rails, and not down the outside of the body — both read longer than the bed actually is.
- 3
Measure over a spray-in liner
If the bed is sprayed, measure over the coating. That is the surface the cover sits on. A drop-in plastic liner is a different matter — if its lip wraps over the top of the rail, it sits between the bed and the cover's clamps.
- 4
Round to the nearest category
Your tape will read something like 61.7" rather than a clean number. Covers are sold in categories, so match the category and then confirm the fit against your exact year.
Colorado bed size — frequently asked
What bed sizes does the Chevrolet Colorado come in?
The 2023–present Chevrolet Colorado is offered with one bed: 5.2 ft (61.7"). Earlier generations were not identical — the table below lists every generation, because a cover bought for the wrong one will not seal.
How long is the Colorado bed in inches?
The 5.2 ft bed measures 61.7 inches along the floor. Manufacturers round these in their brochures — a "5.5 ft" bed is rarely 66 inches exactly — so measure your own floor from the bulkhead to the closed tailgate before ordering anything cut to length.
How do I measure my Colorado bed?
Measure inside the bed, along the floor, from the front bulkhead to the inside face of the closed tailgate. Do not measure the outside of the body, and do not include the tailgate when it is down. If a spray-in liner is fitted, measure over it, since that is the surface a cover clamps against.
What size tonneau cover fits a Colorado?
Covers are sold by bed category, and the Chevrolet Colorado falls into these categories: Short / compact and 6.5 ft. Match the category to your own bed, then confirm the exact year and generation — bed rails, tie-down systems and cargo-management tracks change between generations even when the length does not.
Did the Colorado bed size change over the years?
Yes. Across 2005–2026 the bed line-up changed between generations, and inside lengths moved even where the marketing name stayed the same. Go by your truck's year in the table below rather than by the badge, especially when buying a used cover.
Will a cover from a different Colorado year fit mine?
Only if the bed length and the rail design both match. Length is the first check and the easiest to get right; the second is how the cover clamps, because a generation change often moves the rail profile or adds a factory cargo track. Check both before buying a used cover.
