20ft reefer container dimensions
20ft reefer container dimensions: typical interior 5.44 × 2.29 × 2.27 m, 28.3 CBM, payload about 27,400 kg, tare about 3,080 kg. The machinery bunker and insulation cut cube versus a dry 20ft. Airflow and stow rules can beat a pure carton count. Planning figures, not a CSC plate.
How many of your cartons fit?
Carton count
Floor-packed and stacked to the ceiling, upright, no weight cap. Full payload logic lives on the container loading calculator.
Do not plan a reefer like a dry box. Leave air channels the operator specifies, and confirm setpoint, humidity and vent. Cube numbers here ignore those operational voids.
Interior dimensions used
| L × W × H | Inches | Rated cube |
|---|---|---|
| 5.44 × 2.29 × 2.27 m | 214.2 × 90.2 × 89.4 in | 28.3 CBM |
Dimensions vary by manufacturer and build year. Practical loading efficiency is typically 80–90% of rated CBM.
Formula
- Per layer = integer pack of carton footprint on 5.44 × 2.29 m.
- Layers = floor(2.27 m / carton height).
- Cartons = per layer × layers (no payload cap on this mini tool).
Questions
How many CBM is a 20ft reefer?
Rated capacity is about 28.3 CBM from typical internals of 5.44 × 2.29 × 2.27 m (214.2 × 90.2 × 89.4 in). Plan 80–90% in real stuffing.
Are these CSC-plate numbers?
No. They are published typicals. The plate on the box you receive is the authority for tare, payload and, in practice, the interior you pack.
