Box Volume
Three sides in centimetres or inches. Volume uses the numbers you type — sides are not rounded. Dimensional weight, which rounds each side up, is a separate tool. No postage rates.
Frequently asked questions
Does this round the sides?
No. Volume uses the sizes you typed. The dimensional-weight tool rounds each side up first.
Does this give a shipping price?
No. It only converts dimensions into volume. Not shipping advice — postage rates and carrier rules are not included.
