How many 18 × 18 × 16 in boxes fit in a 53ft trailer?
18 × 18 × 16 in boxes of 457 × 457 × 406 mm (also called 3 cubic foot boxes, medium moving boxes) in a 53-foot dry van trailer (US) — inner dimensions 16,000 × 2,540 × 2,790 mm. Calculated by the Cubestow engine on 2026-09-08.
Boxes may be laid on any side. 94% of the space used, 6 layers high, about 17,640 kg (86% 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 North American dry van. Inner width around 100 in (2,540 mm) fits two 48 × 40 in pallets side by side either way round; legal gross weight, not space, usually caps the load.
The simple grid estimate is 35 along the length × 5 across × 6 high = 1,050. The engine found 1,260 — 210 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 53ft trailer?
1,260 18 × 18 × 16 in boxes of 457 × 457 × 406 mm fit in a 53ft trailer (inner dimensions 16,000 × 2,540 × 2,790 mm), boxes may be laid on any side. That uses 94% of the 113.4 m³ available and weighs about 17,640 kg.
What are the inner dimensions of a 53ft trailer?
Typical inner dimensions are 16,000 mm long, 2,540 mm wide and 2,790 mm high (629.9 × 100.0 × 109.8 in), giving 113.4 m³ of space and a rated payload of about 20,400 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?
1,260 × 14 kg ≈ 17,640 kg, which is 86% of the 20,400 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.
