The foot length is the last the number is built on, rounded to whole millimetres.
How it works
There is no international standard for shoe sizes. The systems grew up separately and measure different things, which is why a conversion can never be exact.
European numbers are counted in Paris points, two thirds of a centimetre, or 6.67 millimetres, and measure the last rather than the foot. The last is about fifteen millimetres longer than the foot, which is the room for the toes. Half European numbers appear in shops but are no part of the system.
British numbers are counted in barleycorns, a third of an inch, from a zero point with no explanation beyond tradition. American men’s sizes sit one step above the British ones, and women’s sizes a further one and a half.
Japanese numbers and Mondopoint are simply the length of the foot in centimetres. It is the only system that measures what you actually want to know.
Measure your foot by standing on a sheet of paper with the heel against a wall and marking the longest toe. Measure in the evening, when the foot is at its largest, and take the larger of the two.
Expect brands to differ by half a size to a full size. The table gives the starting point, not the answer.
