40 ft container dimensions and capacity

Independent site, not a government service. General information, not customs advice.

A 40 foot box has twice the volume of a 20 foot one, but not twice the payload. Enter your cargo and compare it with both limits.

The 40 foot general purpose container is 12,192 millimetres long on the outside, with the same 2,438 width and 2,591 height as a 20 foot box. The carrier sheet we read gives an inside of 12,032 by 2,352 by 2,395 millimetres, a door of 2,340 by 2,292, and a capacity of 67.7 cubic metres. Its tare is 3,700 kilograms, and the listed payload is 28,800 kilograms in that first series, with a gross of 32,500. Other series on the same sheet show 30,480 kilograms gross and 26,700 of payload. The point to remember is that payload falls slightly as the box grows, so this size is for goods that run out of space before weight. Divide your weight by your volume to see which case is yours.

Goods that suit it

A simple test: divide your cargo's weight by its volume. If it is well under 425 kilograms per cubic metre, space will run out first, and that is worth testing for goods such as clothing or furniture. If it's over, weight runs out first and part of the box stays empty. This ratio is our arithmetic from the table, not a rule from anybody.

Before you book

We read no Indian rule on trucks or warehouse access for this size, so check with your haulier and your warehouse that the box can be received. Time spent unpacking may count against your contract's free days: see detention charges. If you are close to the volume limit but light on weight, compare it with the high cube version. Use the second tool on this page to test your carton in this box, then see all three in the dimensions table. The source figures are from a carrier brochure with stated tolerances, and we name it only as a source.

Questions people ask

What are the inside dimensions of a 40 ft container?

In the specification we read, 12,032 millimetres long, 2,352 wide and 2,395 high, which is 39 feet 5 and five eighths inches by 7 feet 8 and five eighths inches by 7 feet 10 and a quarter inches. Some series differ by a few millimetres. Plan with a margin, as the sheet itself warns that production tolerances exist.

How many cubic metres does a 40 ft container hold?

The nominal figure in the sheet we read is 67.7 cubic metres. You will not be able to fill all of that with cartons or pallets. Work out your cargo in the CBM calculator and then test your carton size in the loading tool on this page. We publish no general working figure, because it depends on packing.

Can one 40 ft container replace two 20 ft containers?

By volume, yes on the sheet we read: 67.7 cubic metres against 66.4 in two boxes. By weight, no: 28,800 kilograms of payload against 60,400. So the answer depends on your cargo density. We publish no freight rates, so price is the part we cannot settle. Get quotes for both and compare them against your actual cargo.
