How many 24 × 18 × 18 in boxes fit in a 40ft high cube?

24 × 18 × 18 in boxes of 610 × 457 × 457 mm (also called 4.5 cubic foot boxes, large moving boxes) in a 40-foot high-cube container (40HC) — inner dimensions 12,032 × 2,352 × 2,698 mm. Calculated by the Cubestow engine on 2026-09-08.

The answer in detail

The large 4.5 cubic foot moving and shipping box.

Same footprint as a 40GP with about 30 cm more height — the workhorse of e-commerce and consumer-goods shipping because the extra layer of cartons is almost free.

The simple grid estimate is 19 along the length × 5 across × 5 high = 475. The engine found 551 — 76 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 24 × 18 × 18 in boxes fit in a 40ft high cube?

551 24 × 18 × 18 in boxes of 610 × 457 × 457 mm fit in a 40ft high cube (inner dimensions 12,032 × 2,352 × 2,698 mm), boxes may be laid on any side. That uses 92% of the 76.4 m³ available and weighs about 8,816 kg.

What are the inner dimensions of a 40ft high cube?

Typical inner dimensions are 12,032 mm long, 2,352 mm wide and 2,698 mm high (473.7 × 92.6 × 106.2 in), giving 76.4 m³ of space and a rated payload of about 26,500 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.

How much does a full load of 24 × 18 × 18 in boxes weigh?

551 × 16 kg ≈ 8,816 kg, which is 33% of the 26,500 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.

Other cargo in a 40ft high cube

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.
