How many boxed washing machines fit in a 20ft reefer?
Boxed washing machines of 650 × 650 × 900 mm (also called front-load washers in cartons) 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.
Upright, stacked at most 2 high. 64% of the space used, 2 layers high, about 3,600 kg (13% of payload). Open this load in the 3D planner →

The answer in detail
A boxed front-loading washing machine is about 650 × 650 × 900 mm and 70–80 kg. Packaging is rated for stacking two high, which is how they travel in containers.
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 8 along the length × 3 across × 2 high = 48. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (48).

Frequently asked
How many boxed washing machines fit in a 20ft reefer?
48 boxed washing machines of 650 × 650 × 900 mm fit in a 20ft reefer (inner dimensions 5,444 × 2,294 × 2,276 mm), upright, stacked at most 2 high. That uses 64% of the 28.4 m³ available and weighs about 3,600 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 boxed washing machines weigh?
48 × 75 kg ≈ 3,600 kg, which is 13% 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, 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.
