Box Trucks: dimensions & payload capacity
Cargo box dimensions and payload for commercial straight trucks and vans by class, from cargo vans and Luton bodies up to 26ft box trucks and European 26t rigids.
Interior cargo dimensions in inches; payload is maximum cargo weight, not gross vehicle or gross container weight. Figures are the published specifications of the manufacturer, carrier, or standards body linked on each row, and vary by make, model, and year. Treat them as planning numbers and confirm the specific unit before you load it.
About these numbers
A box truck is a cargo body mounted on a single chassis, with no articulation, which is why the trade calls them straight trucks. They are the backbone of last-mile delivery, regional touring, and any job where a semi cannot get to the door. In North America they are sized by cargo box length, from about 16 ft up to 26 ft. The 26 ft is the largest most operators can run without a commercial driver's licence, because manufacturers deliberately spec it just under the 26,001 lb gross vehicle weight threshold, and that constraint is why its payload is often lower than its size suggests. Europe and Asia size the same class of vehicle by gross weight instead: a 7.5 t box lorry, an 18 t or 26 t rigid, a Japanese 2 t or 4 t flat deck. A Luton body extends over the cab to steal a little extra cargo volume, and Australian operators call the enclosed version a pantech. Cargo vans sit at the bottom of the range, and a high-roof extended van gives you stand-up height and about 14 ft of floor on a car licence. Note that the open flat-deck classes, including the Japanese kei and 2 t and 4 t trucks, quote a drop-side gate height rather than an enclosed ceiling, so treat that number as a side wall, not a roof.
Frequently asked questions
- What are the interior dimensions of a 26ft box truck?
- A 26 ft box truck has roughly 312 x 97 x 99 in of interior cargo space, about 1,700 cubic feet, with a payload usually around 10,000 lb. It is the largest straight truck most people can drive without a commercial licence, because it is built to stay under 26,001 lb gross vehicle weight.
- Do you need a CDL to drive a box truck?
- Not for the common commercial classes up to 26 ft. In the US a commercial driver's licence is required above 26,001 lb gross vehicle weight, and manufacturers spec box trucks to sit just under it. Anything heavier, and any European lorry above 3.5 t, needs the equivalent commercial entitlement. Weight rules vary by state and country, so confirm locally.
- How big is a 7.5 tonne lorry?
- A European 7.5 t box lorry gives about 225 x 94 x 85 in of cargo box (5.71 x 2.4 x 2.15 m), roughly 29.5 cubic metres, with a payload near 2,300 kg. It is the standard European distribution and touring truck and needs a C1 entitlement to drive.
- What is the difference between a box truck and a semi-trailer?
- A box truck has the cargo body permanently mounted on the same chassis as the cab, so it drives as one unit. A semi-trailer is a separate body pulled by a tractor and can be dropped, swapped, and loaded independently. Box trucks top out around 1,700 cubic feet; a 53 ft trailer carries more than twice that.
- How much can a cargo van carry?
- A high-roof extended cargo van such as a Sprinter 170 EXT or Transit 148 EL gives roughly 172 x 70 x 80 in of cargo space and carries about 3,500 to 3,900 lb. Stand-up interior height is the main reason to choose one over a smaller van.
- Why is the height figure so small on the Japanese flatbed trucks?
- Because those rows are open flat decks, not enclosed boxes. The height shown is the drop-side gate (あおり) that folds down for loading, not a ceiling. Cargo can be stacked well above it, subject to the legal overall vehicle height and how it is secured.
