How many 18 × 18 × 16 in boxes fit in a 13.6 m trailer?
18 × 18 × 16 in boxes of 457 × 457 × 406 mm (also called 3 cubic foot boxes, medium moving boxes) in a 13.6 m curtainsider / box trailer (EU) — inner dimensions 13,600 × 2,450 × 2,700 mm. Calculated by the Cubestow engine on 2026-09-08.
Boxes may be laid on any side. 96% of the space used, 6 layers high, about 14,210 kg (59% of payload). Open this load in the 3D planner →

The answer in detail
The "3.0 cubic foot" medium moving box (18 × 18 × 16 in) is the box most US movers use for the bulk of a household. Lying it on its side gains height in some containers, which is why the any-orientation count is higher.
The standard European semi-trailer. Curtainsiders are loaded from the side, so pallets can be turned freely; the 2,450 mm inner width is what makes three EUR pallets (3 × 800) fit across.
The simple grid estimate is 29 along the length × 5 across × 6 high = 870. The engine found 1,015 — 145 more than either uniform grid — by mixing orientations so that the leftover strip along the wall is used and by choosing the orientation that gives the most layers. The top view above shows the pattern.

Frequently asked
How many 18 × 18 × 16 in boxes fit in a 13.6 m trailer?
1,015 18 × 18 × 16 in boxes of 457 × 457 × 406 mm fit in a 13.6 m trailer (inner dimensions 13,600 × 2,450 × 2,700 mm), boxes may be laid on any side. That uses 96% of the 90.0 m³ available and weighs about 14,210 kg.
What are the inner dimensions of a 13.6 m trailer?
Typical inner dimensions are 13,600 mm long, 2,450 mm wide and 2,700 mm high (535.4 × 96.5 × 106.3 in), giving 90.0 m³ of space and a rated payload of about 24,000 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
How much does a full load of 18 × 18 × 16 in boxes weigh?
1,015 × 14 kg ≈ 14,210 kg, which is 59% of the 24,000 kg payload — so this load is limited by space, not weight.
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.
