Put a tape measure on the bed floor against the bulkhead (the wall behind the cab).

Measure straight back to the inside of the closed tailgate.
- 4
Match that number to a bed length above — covers are sold by category (5.5 ft, 6.5 ft, 8 ft…), so round to the nearest one.

What fits in a Gladiator bed
Bed length in inches only means something once you know what it swallows. Here's how the loads people actually haul line up against every Gladiator bed on record.
| Load | Needs | 5 ft · 60.3" |
|---|---|---|
| 4×8 ft sheet of plywood or drywall | 96" | Won't fit |
| 8 ft 2×4s and trim lumber | 96" | Won't fit |
| Full-size dirt bike | 85" | Won't fit |
| Adult mountain bike, wheels on | 70" | Tailgate down |
| Two-person truck bed tent | 60" | Fits, tailgate up |
| Standard 48×40 in shipping pallet | 48" | Fits, tailgate up |
"Tailgate down" assumes the roughly 18 inches a dropped tailgate adds on a typical pickup — measure yours before you count on it, and strap anything that overhangs. Width is the other half of the answer: a 48-inch sheet only lies flat on the bed floor when the wheel wells are more than 48 inches apart, otherwise it rides on top of the arches. For cubic feet of mulch, soil or gravel, run your dimensions through the bed volume calculator.

Gladiator bed size — frequently asked
What bed sizes does the Jeep Gladiator come in?
The Jeep Gladiator has been offered with 1 bed length: 5 ft (60.3"). The exact bed on your truck depends on its model year and cab — choose your year above to see which covers fit.
How do I measure my Gladiator bed length?
Measure the inside floor of the bed, from the bulkhead (the wall behind the cab) to the inside of the closed tailgate. Round to the nearest standard size — tonneau covers are sold by bed-length category (e.g. 5.5 ft, 6.5 ft, 8 ft), not the exact inch.
What bed size is the newest Gladiator?
The current Gladiator (2020–present) comes with 5 ft (60.3").
Will a tonneau cover from an older Gladiator fit a newer one?
Not necessarily. Covers are matched to a specific generation and bed length, and both the bed length and the rail design can change between generations. Always match your exact model year and bed size before buying — the year-by-year table below shows where the Gladiator changed.
Will a 4×8 sheet of plywood fit in a Gladiator?
No. Even the longest Gladiator bed (60.3") plus a dropped tailgate falls short of 96 inches, so an 8 ft sheet will overhang and needs a flag and proper tie-downs. Width matters too: a 48-inch sheet only lies flat on the floor if the gap between the wheel wells is wider than 48 inches — on mid-size trucks it rides on top of the wheel arches instead.
How much can a Gladiator tow?
Properly equipped, the Gladiator has been rated up to 7,700 lb across the generations on this page, with a maximum payload of about 1,725 lb. Those are best-case figures for a specific engine, cab and axle combination — your truck's door-jamb sticker and owner's manual are the numbers that count. Run them through the towing and payload calculators to see what's actually left for a trailer once passengers and gear are on board.
What cab configurations does the Gladiator come in?
The Gladiator has been offered as Crew Cab. Cab choice is what usually decides bed length — a bigger cab on the same wheelbase means a shorter bed, which is why two trucks from the same year can need different covers.
Does a tonneau cover on a Gladiator improve gas mileage?
A little, and only at highway speed. Independent testing puts the gain on a typical pickup at roughly 1–2%, which is real but small — on most Gladiator trucks that's a few dollars a tank, not a payback plan. Buy a cover for the dry, locked, secure bed; treat the mileage as a bonus.
