40ft Container CBM Capacity

Check whether your cargo fits a standard 40ft (40GP) container: internal dimensions, real-world loadable CBM, and how many containers your shipment needs.

Quick answers

How many CBM fits in a 40ft container?

The internal volume is about 67.7 CBM, but realistic loading usually reaches 54–58 CBM after gaps, door clearance, and stacking limits.

What are the internal dimensions of a 40ft container?

Approximately 12.03 m long × 2.35 m wide × 2.39 m high, with a door opening of about 2.34 m × 2.28 m.

Is a 40ft container double the price of a 20ft?

No — ocean freight for a 40ft is typically only 20–35% more than a 20ft, which is why high-volume, lighter cargo almost always ships in 40ft equipment.

40ft standard or 40ft high cube?

If your cargo is volume-limited rather than weight-limited, the 40HC adds ~8.7 CBM of height capacity for a small premium and is the default choice for most consumer goods.
