Dry van trailer dimensions
The 53 foot dry van is the default trailer for full truckload freight in the United States. It is as long and as wide as you can run on the interstate without a permit, which is why almost every fleet standardised on it. The 48 foot van and the 28 foot pup still cover specific lanes.

Dry van size chart
| Trailer | Interior L × W × H | Door opening W × H | Cubic capacity | Typical payload | 48×40 pallets |
|---|---|---|---|---|---|
| 53 ft van | ~630" × 98–100" × 108–110" | ~93–98" × 105–110" | ~3,900–4,050 cu ft | 42,000–45,000 lb | 26 straight |
| 48 ft van | ~570" × 98–100" × 108–110" | ~93–98" × 105–110" | ~3,550–3,650 cu ft | 42,000–45,000 lb | 24 straight |
| 28 ft pup | ~330" × 96–100" × 106–110" | ~93–96" × 104–108" | ~2,000–2,100 cu ft | ~22,000–24,000 lb | 14 straight |
Why the interior is narrower than the trailer
The exterior width of a dry van is 102 inches, the legal maximum on US highways without a permit. Wall construction takes one to two inches per side, which is how a 102 inch trailer ends up with a 98 to 100 inch interior. That two inch difference is the whole reason two 48 inch pallets turned sideways are a tight fit rather than a comfortable one.
Height works the same way. A standard van stands 13 feet 6 inches tall on the outside, but the floor structure, undercarriage and roof bows consume the difference, leaving roughly 108 to 110 inches of usable cargo height.
Federal limits worth knowing
Three numbers govern most planning decisions:
- 80,000 pounds gross combination weight on the interstate system without a permit. That covers tractor, trailer and cargo together, which is why a tractor and trailer weighing 32,000 to 35,000 pounds empty leaves you 45,000 pounds of payload rather than a round 50,000.
- 102 inches maximum width.
- 13 feet 6 inches is the practical height ceiling in most states, and it is set by bridge and overpass clearance rather than by one federal rule.
Axle weight matters as much as gross weight. A load can sit comfortably under 80,000 pounds in total and still put you over on the drive or tandem axles because the weight is concentrated in the wrong half of the trailer. Sliding the tandems redistributes it, but only within a limited range, so placement during loading is the real fix.
Cubing out versus weighing out
A 53 foot van gives you roughly 3,900 cubic feet and roughly 45,000 pounds. Divide one by the other and you get about 11.5 pounds per cubic foot. That number is the pivot. Freight denser than that will weigh out before it cubes out; freight lighter than that will fill the trailer with capacity to spare.
Knowing which side of 11.5 you are on tells you immediately whether to optimise your load plan for floor positions or for weight distribution.
Plan the trailer, not just the total
PCTS places every item into a 53ft, 48ft or 28ft van, checks each one against the door opening, tracks running weight against the payload limit, estimates axle loads, and prints a back-to-front loading sequence.

How many cubic feet are in a 53 foot trailer?
About 3,900 to 4,050 cubic feet, depending on interior height and exact usable length. To calculate it yourself, multiply interior length, width and height in inches and divide by 1,728.
How many pallets fit in a 53 foot trailer?
26 standard 48×40 GMA pallets loaded straight, two across in 13 rows. Turned or pinwheel patterns can push that to 28 or 30, but they need cooperative dock crews at both ends and enough interior width to spare.
What is the maximum payload of a dry van?
Commonly 42,000 to 45,000 pounds. The exact figure is 80,000 pounds minus the actual weight of the tractor and trailer, so a lightweight day cab buys you payload that a heavy sleeper does not.
What is the difference between a 48ft and a 53ft van?
Five feet of floor, roughly 350 cubic feet, and two pallet positions. Width, height, door opening and weight limit are effectively identical. The 48 was the standard before the 53 took over and still runs on lanes with tight access or specific state restrictions.
How tall is the inside of a semi trailer?
Roughly 108 to 110 inches, about nine feet. The exterior is 13 feet 6 inches, with the floor structure and roof taking the rest.
