How many 1100 × 1100 mm pallets fit in a 20ft reefer?
1100 × 1100 mm pallets of 1,100 × 1,100 × 1,000 mm (also called Asian pallets, JIS pallets, T11 pallets) in a 20-foot refrigerated container (20RF) — inner dimensions 5,444 × 2,294 × 2,276 mm. Calculated by the Cubestow engine on 2026-09-08.
Single layer, floor-loaded (standard practice). 34% of the space used, 1 layer high, about 3,200 kg (12% 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.
The refrigeration unit and insulated walls take space, so a reefer is shorter, narrower and lower inside than a dry 20ft. Leave the T-floor and the air return clear.
The simple grid estimate is 4 along the length × 2 across × 1 high = 8. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (8).
Variants
| Loading rule | Fits | Layers | Volume used | Total weight |
|---|---|---|---|---|
| Single layer, floor-loaded (standard practice) (headline figure) | 8 | 1 | 34% | 3,200 kg (12% of payload) |
| Double-stacked (only if each loaded pallet is at most 1,138 mm tall and rated to carry another) | 16 | 2 | 68% | 6,400 kg (23% of payload) |

Frequently asked
How many 1100 × 1100 mm pallets fit in a 20ft reefer?
8 1100 × 1100 mm pallets of 1,100 × 1,100 × 1,000 mm fit in a 20ft reefer (inner dimensions 5,444 × 2,294 × 2,276 mm), single layer, floor-loaded (standard practice). That uses 34% of the 28.4 m³ available and weighs about 3,200 kg.
What are the inner dimensions of a 20ft reefer?
Typical inner dimensions are 5,444 mm long, 2,294 mm wide and 2,276 mm high (214.3 × 90.3 × 89.6 in), giving 28.4 m³ of space and a rated payload of about 27,400 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?
8 × 400 kg ≈ 3,200 kg, which is 12% of the 27,400 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.
