40ft open-top container
A 40-foot open top is a dry-box floor with a tarpaulin or hard roof so cargo can be craned in. Typical internals are about 12.03 × 2.35 × 2.35 m and 66.4 CBM — less height than a closed 40ft because of the header bar. Use it for machinery that needs ISO corner castings, not as a cheap high cube.

Carton count
Floor-packed and stacked to the ceiling, upright, no weight cap. Full payload logic lives on the container loading calculator.
Overheight cargo that sticks above the header is a different permit and lashing problem. This page packs as if the roof is closed at the typical interior height.
Interior dimensions used
| L × W × H | Inches | Rated cube |
|---|---|---|
| 12.03 × 2.35 × 2.35 m | 473.6 × 92.5 × 92.5 in | 66.4 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(2.35 m / carton height).
- Cartons = per layer × layers (no payload cap on this mini tool).
Questions
How many CBM is a 40ft open top?
Rated capacity is about 66.4 CBM from typical internals of 12.03 × 2.35 × 2.35 m (473.6 × 92.5 × 92.5 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.
