Shoe sizes change the moment you shop across borders, and a US 9 is not a UK 9 or an EU 9. Enter a size in one system and see it in US, UK, EU and centimetres, so an online order from another country has a fighting chance of fitting.

Common use cases
Order from abroadConvert your usual size to the system a foreign shop uses before you buy.
Read a size chartMake sense of a listing that only gives EU or centimetres when you think in US or UK.
Buy a giftTurn a known size into the local one so a present actually fits.
Compare scalesCheck across systems where the same number means different things.
Good to know
Brands are not consistentConversion charts are a guide, not a guarantee. Two brands can label the same foot differently, so treat the result as a starting point.
Measure your foot in centimetresThe most reliable input is the actual length of your foot. Centimetres cut through the US, UK and EU confusion.
Men's and women's differThe same number is a different size in men's and women's scales, so pick the right one or you will be off by a size or more.
Allow for width and shapeLength is only half the fit; width and instep vary by brand and last, which a single number cannot capture.
