What fits in a Ram 1500 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 Ram 1500 bed on record.
| Load | Needs | 5.7 ft · 67.4" | 6.4 ft · 76.3" | 8 ft · 98.3" |
|---|---|---|---|---|
| 4×8 ft sheet of plywood or drywall | 96" | Won't fit | Won't fit | Fits, tailgate up |
| 8 ft 2×4s and trim lumber | 96" | Won't fit | Won't fit | Fits, tailgate up |
| Full-size dirt bike | 85" | Tailgate down | Tailgate down | Fits, tailgate up |
| Adult mountain bike, wheels on | 70" | Tailgate down | Fits, tailgate up | Fits, tailgate up |
| Two-person truck bed tent | 60" | Fits, tailgate up | Fits, tailgate up | Fits, tailgate up |
| Standard 48×40 in shipping pallet | 48" | Fits, tailgate up | Fits, tailgate up | 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.

Same length still isn't the same cover — rail height and bed-rail profile differ by truck. Confirm with the fitment checker before you buy or swap.

Ram 1500 bed size — frequently asked
What bed sizes does the Ram 1500 come in?
The Ram 1500 has been offered with 3 bed lengths: 5.7 ft (67.4"), 6.4 ft (76.3") and 8 ft (98.3"). 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 Ram 1500 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 Ram 1500?
The current Ram 1500 (2019–present) comes with 5.7 ft (67.4") and 6.4 ft (76.3").
Will a tonneau cover from an older Ram 1500 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 Ram 1500 changed.
Will a 4×8 sheet of plywood fit in a Ram 1500?
Yes — the longest Ram 1500 bed on record is 98.3", so a full 4×8 sheet lies flat with the tailgate closed. 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.
What's the difference between the short and long bed Ram 1500?
Across the model's history the beds run from 67.4" to 98.3" — a difference of 31 inches of usable floor. The longer bed hauls more and takes longer sheet goods, the shorter bed is easier to park and turn. They take different tonneau covers, so the bed you have decides which cover part number you order.
How much can a Ram 1500 tow?
Properly equipped, the Ram 1500 has been rated up to 11,550 lb across the generations on this page, with a maximum payload of about 2,370 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 Ram 1500 come in?
The Ram 1500 has been offered as Regular Cab, Quad Cab, Crew Cab and Mega 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 Ram 1500 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 Ram 1500 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.
