How many half pallets fit in a 20ft reefer?
Half pallets of 800 × 600 × 900 mm (also called Düsseldorfer pallets, 800 × 600 pallets, display 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). 36% of the space used, 1 layer high, about 4,800 kg (18% of payload). Open this load in the 3D planner →

The answer in detail
The 800 × 600 mm half pallet ("Düsseldorfer") is the retail display pallet. Three fit across a 2,352 mm container with the 600 mm side across (3 × 600 = 1,800 mm), and the plan mixes in turned pallets to use the remaining width.
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 6 along the length × 3 across × 1 high = 18. The engine found 24 — 6 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) | 24 | 1 | 36% | 4,800 kg (18% of payload) |
| Double-stacked (only if each loaded pallet is at most 1,138 mm tall and rated to carry another) | 48 | 2 | 73% | 9,600 kg (35% of payload) |

Frequently asked
How many half pallets fit in a 20ft reefer?
24 half pallets of 800 × 600 × 900 mm fit in a 20ft reefer (inner dimensions 5,444 × 2,294 × 2,276 mm), single layer, floor-loaded (standard practice). That uses 36% of the 28.4 m³ available and weighs about 4,800 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 half pallets weigh?
24 × 200 kg ≈ 4,800 kg, which is 18% 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.
