How internal measurements are taken

  • Internal width: between the two longest sides, inside the container.
  • Internal length: between the two shortest sides, inside the container.
  • Internal height: from the floor to the ceiling, inside the container.
  • Door opening width: between the inside right and left of the support frames, allowing a narrow gap for the door’s opening radius.
  • Door opening height: from the floor to the underside of the horizontal cross support (the top of the door opening). It is usually the same as or less than the internal height.

External dimensions

For most shippers the cargo capacity matters most, but you may also need external dimensions for transport or loading, for example to check there is room to open the doors. Contact us if you need the external dimensions of any container.

A guide only

Dimensions differ slightly between carriers, so use this information as a guide. For advice on the right container for your cargo, contact us. If your cargo is too large for a container, we can ship heavy lift and oversize cargo by roll on roll off services or heavy lift ships (see roll trailer shipping).

A high cube is taller than a standard general purpose container of the same length, giving more cubic capacity. See each container's page for exact figures.

Flat racks, open tops and hard tops suit oversize or heavy items; cargo too large for any container can go by roll on roll off or heavy lift ship.

Yes, slightly. Use these figures as a guide and confirm with us before booking.
