How many 400 × 300 × 300 mm boxes fit in a 20ft container?
400 × 300 × 300 mm boxes of 400 × 300 × 300 mm (also called 40 × 30 × 30 cm cartons, quarter-Euro cartons) in a 20-foot standard container (20GP) — inner dimensions 5,898 × 2,352 × 2,393 mm. Calculated by the Cubestow engine on 2026-09-08.
Boxes may be laid on any side. 84% of the space used, 11 layers high, about 4,674 kg (17% of payload). Open this load in the 3D planner →

The answer in detail
The 400 × 300 footprint is a quarter of a EUR pallet deck (eight per layer), which makes it a favourite e-commerce shipping carton.
The most common dry container for smaller export loads. Inner dimensions are typical for a steel ISO 20GP; individual boxes vary by a few centimetres, and the door opening (about 2,340 × 2,280 mm) is slightly smaller than the inside.
The simple grid estimate is 14 along the length × 7 across × 11 high = 1,078. The engine found 779 — 93 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 400 × 300 × 300 mm boxes fit in a 20ft container?
779 400 × 300 × 300 mm boxes of 400 × 300 × 300 mm fit in a 20ft container (inner dimensions 5,898 × 2,352 × 2,393 mm), boxes may be laid on any side. That uses 84% of the 33.2 m³ available and weighs about 4,674 kg.
What are the inner dimensions of a 20ft container?
Typical inner dimensions are 5,898 mm long, 2,352 mm wide and 2,393 mm high (232.2 × 92.6 × 94.2 in), giving 33.2 m³ of space and a rated payload of about 28,200 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
How much does a full load of 400 × 300 × 300 mm boxes weigh?
779 × 6 kg ≈ 4,674 kg, which is 17% of the 28,200 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.
