How many 500 × 400 × 400 mm boxes fit in a 12 t truck?

500 × 400 × 400 mm boxes of 500 × 400 × 400 mm (also called 50 × 40 × 40 cm cartons) in a 12-tonne box truck — inner dimensions 7,300 × 2,480 × 2,500 mm. Calculated by the Cubestow engine on 2026-09-08.

Boxes may be laid on any side. 88% of the space used, 9 layers high, about 5,500 kg (100% of payload). Payload-limited: 540 would fit by space alone. Open this load in the 3D planner →

The answer in detail

A large parcel carton just under the 80 L mark, common for household goods and for consolidating smaller cartons.

A 7.3 m rigid body with around 5.5 t of payload — the usual size for regional pallet distribution.

The simple grid estimate is 14 along the length × 6 across × 9 high = 756. The engine's validated plan holds 500, below the raw grid because the payload limit cap the load.

Weight, not space, is the limit here. By geometry 540 500 × 400 × 400 mm boxes fit, but at about 11 kg each the rated payload of 5,500 kg is reached at 500. Road weight limits on the way to or from the port can be lower still.

Frequently asked

How many 500 × 400 × 400 mm boxes fit in a 12 t truck?

500 500 × 400 × 400 mm boxes of 500 × 400 × 400 mm fit in a 12 t truck (inner dimensions 7,300 × 2,480 × 2,500 mm), boxes may be laid on any side. That uses 88% of the 45.3 m³ available and weighs about 5,500 kg.

What are the inner dimensions of a 12 t truck?

Typical inner dimensions are 7,300 mm long, 2,480 mm wide and 2,500 mm high (287.4 × 97.6 × 98.4 in), giving 45.3 m³ of space and a rated payload of about 5,500 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.

Why does the payload limit matter for 500 × 400 × 400 mm boxes?

Geometrically 540 500 × 400 × 400 mm boxes would fit, but at about 11 kg each the 12 t truck's 5,500 kg payload is reached at 500. Heavy cargo fills the weight allowance before the space.

How was this number calculated?

By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing all six orientations, stacking with at least 80% base support and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.

Other cargo in a 12 t truck

Assumptions. Cargo is modelled as rigid rectangular boxes with the outer dimensions above; the container's typical inner dimensions and rated payload are used; every box needs at least 80% of its base supported; no dunnage, straps or door clearance are reserved. The plan is one of many optimal or near-optimal arrangements — the engine's plan was checked for overlaps, support, orientation and weight, and the count is what it achieved within 1.4 s of search. Real containers vary by manufacturer; measure yours for tight loads.
