How many UK standard pallets fit in a 40ft reefer?
UK standard pallets of 1,200 × 1,000 × 1,000 mm (also called industrial pallets, 1200 × 1000 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). 35% of the space used, 1 layer high, about 9,000 kg (31% of payload). Open this load in the 3D planner →

The answer in detail
The 1,200 × 1,000 mm pallet — "UK standard", "industrial" or "ISO 1" — is the common pallet in the UK, in chemicals and in much of Asia-bound trade. Two do not quite fit across a container turned the same way (2 × 1,200 = 2,400 mm), so the plan mixes orientations.
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 9 along the length × 2 across × 1 high = 18. The engine found 20 — 2 more than either uniform grid — by mixing orientations so that the leftover strip along the wall is used. The top view above shows the pattern.
Variants
| Loading rule | Fits | Layers | Volume used | Total weight |
|---|---|---|---|---|
| Single layer, floor-loaded (standard practice) (headline figure) | 20 | 1 | 35% | 9,000 kg (31% of payload) |
| Double-stacked (only if each loaded pallet is at most 1,278 mm tall and rated to carry another) | 40 | 2 | 71% | 18,000 kg (62% of payload) |

Frequently asked
How many UK standard pallets fit in a 40ft reefer?
20 UK standard pallets of 1,200 × 1,000 × 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 35% of the 67.9 m³ available and weighs about 9,000 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 UK standard pallets weigh?
20 × 450 kg ≈ 9,000 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, 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.
