40ft standard container
The 40-foot dry container is the ocean workhorse: about 12.03 × 2.35 × 2.39 m inside, 67.7 CBM rated, payload often near 26,730 kg. You get twice the floor of a 20ft for similar handling events. Pallet counts land around 20–21 GMA or 25 Euro. Interiors move a centimeter by builder — check the 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.
Payload is not double a 20ft. Dense cargo can still weigh out. If you are cube-out and light, look at the 40ft high cube before you look at a second box.
Interior dimensions used
| L × W × H | Inches | Rated cube |
|---|---|---|
| 12.03 × 2.35 × 2.39 m | 473.6 × 92.5 × 94.1 in | 67.7 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 12.03 × 2.35 m.
- Layers = floor(2.39 m / carton height).
- Cartons = per layer × layers (no payload cap on this mini tool).
Questions
How many CBM is a 40ft standard?
Rated capacity is about 67.7 CBM from typical internals of 12.03 × 2.35 × 2.39 m (473.6 × 92.5 × 94.1 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.
