Shoe Size Converter
Convert shoe sizes between UK, US, European and centimetre systems.
The same foot, different numbers
Shoe sizing is a mess of regional systems — a UK size, a US size, a European size, all different numbers for the same foot, plus separate scales for men, women and children. Buying from another country means translating between them. This converts a shoe size across the main systems so you can order with some confidence about what will fit.
Enter a size in one system and see it in the others.
Why sizing is only ever a guide
Be realistic: size conversion gets you close, but shoes are not standardised the way you would hope, and fit varies between brands and even between styles from the same brand. The most reliable measure is the actual length of your foot in centimetres, which several systems are based on, so measuring your foot and matching that beats trusting a converted number alone. Treat the converted size as a strong starting point, and check the brand's own size guide where the fit really matters.
