20′ Dry	6,058 mm	2,438 mm	2,591 mm	≈ 33.2 m³
40′ Dry	12,192 mm	2,438 mm	2,591 mm	≈ 67 m³
40′ HC	12,192 mm	2,438 mm	2,896 mm	≈ 76.3 m³

Which size suits which application?

10 feet

Ideal for compact storage and smaller site requirements. It offers a practical solution where space is limited.

20 feet

It is the most balanced type and the most popular size for general cargo, storage and office/workshop modification applications. View: 20 ft Dry container.

40 ft and High Cube

They reduce the unit cost for high-volume cargo. High Cube units are advantageous for loads requiring extra height and for modifications needing a more spacious interior. View: 40 ft HC container.

45 feet

A strong choice for industrial and storage applications requiring generous internal volume and pallet compatibility. View: 45 ft HC PW container.

Internal or external dimensions?

Container dimensions are usually specified separately as external and internal measurements. For loading plans, internal dimensions and door opening are critical, while compatibility with the installation area depends on the external dimensions You can find detailed dimension tables for all products on our products page .
