Inside a 53ft trailer: 630 × 100 × 110 in — 113.6 m³ (4,010 cu ft), up to 44,000 lb (19,958 kg) of cargo.
53ft dry van. These are the smallest inside sizes among the mainstream makers and fleets we read, and the lowest weight rating — a load planned on them also fits the bigger ones. The volume 113.6 m³ is length × width × height of the numbers below. How many tons: 20 t (44,000 lb) of cargo is the payload limit we plan to.
Each number was read twice, independently, and the two readings compared. “Typical” = not every source is a maker, carrier or regulator. Spec table 2026-10-24.
Payload assumes a standard 5-axle tractor-trailer; a single tandem may not exceed 34,000 lb (warning only).
Legal payload is derived with a dealer trailer weight (Hale 15,000 lb) and a back-calculated tractor weight; a carrier sheet (TBG) prints the same 44,000 lb.
