What fits in an F-350 Super Duty 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 F-350 Super Duty bed on record.
| Load | Needs | 6.75 ft · 81.9" | 8 ft · 98.1" |
|---|---|---|---|
| 4×8 ft sheet of plywood or drywall | 96" | Tailgate down | Fits, tailgate up |
| 8 ft 2×4s and trim lumber | 96" | Tailgate down | Fits, tailgate up |
| Full-size dirt bike | 85" | Tailgate down | Fits, tailgate up |
| Adult mountain bike, wheels on | 70" | Fits, tailgate up | Fits, tailgate up |
| Two-person truck bed tent | 60" | Fits, tailgate up | Fits, tailgate up |
| Standard 48×40 in shipping pallet | 48" | 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.

F-350 Super Duty bed size — frequently asked
What bed sizes does the Ford F-350 Super Duty come in?
The Ford F-350 Super Duty has been offered with 2 bed lengths: 6.75 ft (81.9") and 8 ft (98.1"). 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 F-350 Super Duty 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 F-350 Super Duty?
The current F-350 Super Duty (2023–present) comes with 6.75 ft (81.9") and 8 ft (98.1").
Will a tonneau cover from an older F-350 Super Duty 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 F-350 Super Duty changed.
Will a 4×8 sheet of plywood fit in an F-350 Super Duty?
Yes — the longest F-350 Super Duty bed on record is 98.1", 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 F-350 Super Duty?
Across the model's history the beds run from 81.9" to 98.1" — a difference of 16 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 an F-350 Super Duty tow?
Properly equipped, the F-350 Super Duty has been rated up to 38,000 lb across the generations on this page, with a maximum payload of about 8,000 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 F-350 Super Duty come in?
The F-350 Super Duty has been offered as Regular Cab, SuperCab and 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 an F-350 Super Duty 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 F-350 Super Duty 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.
