A truck bed is the open cargo area at the back of a pickup truck, behind the cab. Merriam-Webster defines this sense of “bed” as an open, usually rectangular cargo area or platform at the rear of a truck. Below: what the parts of a truck bed are called, the main bed types, how sizes work, and the accessories most owners add.
Quick answer: the truck bed (also called the box, cargo box or pickup bed) is the open load area behind a pickup’s cab. It has a floor, two bedsides, a front wall and a tailgate. Beds come in short, standard and long lengths; on the 2026 Ford F-150, Ford lists 5.5, 6.5 and 8.0 ft.
What Does Truck Bed Mean?
“Truck bed” means the cargo area of a pickup: the part you load. The word “bed” here is the cargo-area sense in the dictionary, not a place to sleep. You’ll also hear “box,” “bed of a truck,” “pickup bed” and “cargo box.” They all mean the same thing.
Parts of a Truck Bed
| Part | What it is |
|---|---|
| Bed floor | The flat load surface |
| Bedsides | The two side walls of the bed |
| Front wall (bulkhead) | The wall at the cab end of the bed |
| Tailgate | The hinged rear gate that folds down for loading |
| Wheel wells | The humps over the rear wheels, usually the narrowest point inside the bed |
| Bed rails | The tops of the bedsides, where covers and racks often mount |
| Stake pockets | Openings in the top of the bed rails on many trucks, used for some racks and accessories |
| Tie-down points | Hooks, cleats or anchors for straps (type and location vary by truck) |
Types of Truck Beds
Standard Pickup Bed (Styleside or Fleetside)
The common pickup bed: smooth outer sides, with the wheel wells projecting into the cargo area.
Stepside Bed
The rear fenders sit outside the bedsides, often with a small step between the cab and fender. Stepside beds typically have a narrower cargo box than comparable standard beds.
Flatbed
A flat platform with no fixed bedsides, installed on a chassis-cab truck or used to replace a pickup’s original bed. You can load from the sides as well as the back.
Utility (Service) Body
A work body with lockable side compartments for tools, used by many trades.
Dump Bed
A bed that tilts up to unload loose material like gravel or mulch.
Truck Bed Sizes
Bed lengths are usually described as short, standard and long, but the numbers change from model to model. As one example, Ford’s 2026 F-150 spec page lists bed lengths of 5.5 ft, 6.5 ft and 8.0 ft and a bed width of 50.6 inches. For other trucks, see our truck bed length chart for every brand.
How to measure: measure length along the floor from the inside of the front wall to the inside of the closed tailgate. Measure width wall to wall and between the wheel wells. Measure before you buy a mat, liner, cover or toolbox.
What Truck Beds Are Made Of
Steel is common, and some trucks use aluminum or composite beds. Each material trades weight, dent resistance, corrosion behavior and repair cost differently, so check your truck’s specs for what yours is made of before choosing a liner or repair method. If your steel bed has rust, our guide to bed liner over rust covers the prep.
How Much a Truck Bed Can Carry
Start with the truck, not the bed: stay within its available payload, axle and tire ratings, and any maker limits for the bed or installed equipment. Payload includes occupants, cargo, added accessories and trailer tongue weight. Find the numbers in your owner’s manual and on the tire and loading label on the driver’s door jamb. Position heavy cargo the way the owner’s manual says, keep it low, and secure it to rated tie-down points.

Black Friday Tip and Gift Idea
Black Friday tip: if you plan to buy truck bed gear on Black Friday 2026 (November 27) or Cyber Monday (November 30), measure your bed now: length to the closed tailgate, width between the wheel wells, and whether you have a liner. Then check the current price on Amazon on the day rather than a “was” price.
Gift idea: ratchet straps or a cargo bar suit most pickup owners; for the cargo bar, confirm the bed’s inside width first. For a mat, liner or cover, confirm the recipient’s exact truck and bed length.
