How many 580 × 380 × 330 mm master cartons fit in a 40ft reefer?
580 × 380 × 330 mm master cartons of 580 × 380 × 330 mm (also called shoe master cartons, footwear shipping cartons) in a 40-foot high-cube refrigerated container (40RH) — inner dimensions 11,583 × 2,294 × 2,557 mm. Calculated by the Cubestow engine on 2026-09-08.
Boxes kept this-side-up (turned on the floor plane only). 88% of the space used, 7 layers high, about 9,086 kg (31% of payload). Open this load in the 3D planner →

The answer in detail
A typical footwear master carton (12 pairs) is about 580 × 380 × 330 mm, and is shipped upright so the inner boxes are not crushed.
Inner length and width are reduced by the insulation and the machinery. Cargo must not block the airflow along the ceiling or the T-floor.
The simple grid estimate is 19 along the length × 6 across × 7 high = 798. The engine found 826 — 28 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 580 × 380 × 330 mm master cartons fit in a 40ft reefer?
826 580 × 380 × 330 mm master cartons of 580 × 380 × 330 mm fit in a 40ft reefer (inner dimensions 11,583 × 2,294 × 2,557 mm), boxes kept this-side-up (turned on the floor plane only). That uses 88% of the 67.9 m³ available and weighs about 9,086 kg.
What are the inner dimensions of a 40ft reefer?
Typical inner dimensions are 11,583 mm long, 2,294 mm wide and 2,557 mm high (456.0 × 90.3 × 100.7 in), giving 67.9 m³ of space and a rated payload of about 29,000 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
How much does a full load of 580 × 380 × 330 mm master cartons weigh?
826 × 11 kg ≈ 9,086 kg, which is 31% of the 29,000 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 rotation on the floor plane only, 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.
