Shipping container sizes and dimensions

Internal and external dimensions, door openings, floor area, cubic capacity and payload for 10ft, 20ft, 40ft and 40ft high cube containers.

External dimensions

External sizes are standardised, which is why containers stack and ship anywhere in the world. Use these figures when you plan the footprint on your site, and add clearance around them for the doors and for the delivery truck.

Internal dimensions and capacity

Internal figures are what you actually load into. They vary by an inch or two between manufacturers and between new and used units, so treat them as close approximations rather than guarantees, and leave yourself a margin when something has to fit exactly.

Door openings

The door opening is always narrower and lower than the internal box, and it is the figure that decides whether a pallet, a vehicle or a machine will actually go in. Measure your widest load against this column, not against the internal width.

Weights and payload

Tare weight is the empty container. Payload is the maximum cargo weight the structure is rated to carry. For static storage the payload rating rarely limits you, but it matters if you are loading dense material such as tooling, tiles or aggregate, and the tare weight matters when you arrange craning.

Approximate weights

10ft standard~2,900 lb~22,000 lb
20ft standard~5,000 lb~57,700 lb
40ft standard~8,200 lb~59,000 lb
40ft high cube~8,800 lb~58,400 lb

Which one to buy

  • Height is the deciding factor. Anything taller than about 7ft 6in on a pallet needs a high cube.
  • Two 20ft units beat one 40ft when access is tight, when you want two lockable spaces, or when the ground is uneven.
  • One 40ft beats two 20ft on price per cubic foot and on the amount of uninterrupted floor you get.
  • 10ft units suit gardens, allotments and yards where a 20ft truck cannot turn.
