How many 1100 × 1100 mm pallets fit in a 40ft reefer?
1100 × 1100 mm pallets of 1,100 × 1,100 × 1,000 mm (also called Asian pallets, JIS pallets, T11 pallets) 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.
Single layer, floor-loaded (standard practice). 36% of the space used, 1 layer high, about 8,000 kg (28% of payload). Open this load in the 3D planner →

The answer in detail
The 1,100 × 1,100 mm square pallet (JIS / T11) is standard in Japan, Korea and much of South-East Asia and fits two across an ISO container with room to spare.
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 10 along the length × 2 across × 1 high = 20. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (20).
Variants
| Loading rule | Fits | Layers | Volume used | Total weight |
|---|---|---|---|---|
| Single layer, floor-loaded (standard practice) (headline figure) | 20 | 1 | 36% | 8,000 kg (28% of payload) |
| Double-stacked (only if each loaded pallet is at most 1,278 mm tall and rated to carry another) | 40 | 2 | 71% | 16,000 kg (55% of payload) |

Frequently asked
How many 1100 × 1100 mm pallets fit in a 40ft reefer?
20 1100 × 1100 mm pallets of 1,100 × 1,100 × 1,000 mm fit in a 40ft reefer (inner dimensions 11,583 × 2,294 × 2,557 mm), single layer, floor-loaded (standard practice). That uses 36% of the 67.9 m³ available and weighs about 8,000 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 1100 × 1100 mm pallets weigh?
20 × 400 kg ≈ 8,000 kg, which is 28% 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, no stacking 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.
