How many 16 × 16 × 16 in boxes fit in a 20ft container?
16 × 16 × 16 in boxes of 406 × 406 × 406 mm (also called 2.4 cubic foot boxes, medium boxes) 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. 71% of the space used, 5 layers high, about 3,150 kg (11% of payload). Open this load in the 3D planner →

The answer in detail
A 16 in cube — a common medium shipping box and the size of many subscription and DTC master cartons.
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 × 5 across × 5 high = 350. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (350).

Frequently asked
How many 16 × 16 × 16 in boxes fit in a 20ft container?
350 16 × 16 × 16 in boxes of 406 × 406 × 406 mm fit in a 20ft container (inner dimensions 5,898 × 2,352 × 2,393 mm), boxes may be laid on any side. That uses 71% of the 33.2 m³ available and weighs about 3,150 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 16 × 16 × 16 in boxes weigh?
350 × 9 kg ≈ 3,150 kg, which is 11% 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.
