About this tool

The shoe size converter restates a single shoe size across the systems used around the world at once. Enter a size, pick the region it comes from and whether it is a men or women US size, and US men, US women, UK, EU, and foot length in centimetres all appear together.

These conversions are standard approximations, and this is the most important thing to understand before using them. Shoe sizing is not standardised across brands. Two pairs marked the same size can fit very differently depending on the maker, the last the shoe is built on, the style, and the width. Treat every result here as a starting point for choosing what to try on, not a guarantee of fit. Where you can, measure your foot or try shoes in person before buying.

The tool works by converting your input to foot length in centimetres, then applying the common barleycorn and Paris-point formulas to produce each system. The US and UK scales are based on a length in inches where each size step is one third of an inch, while the European scale uses the Paris point of two thirds of a centimetre. Because the men and women US scales are offset from each other, the category setting tells the tool how to read a US size, while UK, EU, and foot length use a single scale.

Sizes must be greater than zero, and a size outside the range these formulas cover shows a short hint instead of a broken result. For related conversions, try the cm to inches tool, the unit converter, or the typography unit converter.

Frequently asked questions

How accurate is this shoe size converter?
It uses standard approximation formulas, so it gets you close, but it is not exact for every brand. Real fit varies by maker, last, and style. Use the result as a guide and try shoes on where possible.
How do I convert a US size to EU?
Enter the US size, choose the US region, and set men or women. The tool finds your foot length and shows the matching EU size along with UK and centimetres.
Why do I need to choose men or women?
The US men and US women scales are offset from each other, so the same number means different foot lengths. The category tells the tool which scale your US size is on. UK, EU, and foot length use one scale.
Can I convert from a foot measurement?
Yes. Choose the foot length option, enter the length in centimetres, and the tool shows the matching US men, US women, UK, and EU sizes. Measuring your foot is often the most reliable starting point.
Is my input sent anywhere?
No. Every conversion happens on your device as you type. Nothing you enter is uploaded, logged, or stored.
