How many boxes fit in a 20ft container?

Updated September 28, 2026Figures calculated with our 3D loading engine

Short answer

It depends on the carton size. A standard 20ft container holds about 262 cartons of 60 × 40 × 40 cm, 472 cartons of 50 × 40 × 30 cm or 931 cartons of 30 × 30 × 30 cm. That uses about 25–28 m³ of the container's 33.1 m³, because boxes rarely divide the container dimensions exactly.

Each number is the result of a full 3D loading plan for a 20ft dry container (590 × 235 × 239 cm inside). Cartons may be turned in any direction to fill the space. If your cartons must stay upright, the count can be a few percent lower. The calculator handles that with the “This side up” option.

How to estimate it yourself

Divide each inside dimension by the matching carton dimension, round down, and multiply: for 60 × 40 × 40 cm cartons that is ⌊590 ÷ 60⌋ × ⌊235 ÷ 40⌋ × ⌊239 ÷ 40⌋ = 9 × 5 × 5 = 225. Turning some rows to use the gaps raises it to 262. That is why a loading calculator usually beats hand math by 5–15%.

Weight check

A 20ft container carries about 28,200 kg. 262 cartons at 20 kg each is 5,240 kg, well within the limit. Heavy goods such as tiles, fasteners or liquids can reach the weight limit long before the container is full; see container weight limits.
