Shoe Size Converter
Convert shoe sizes between regions
About the Shoe Size Converter
Buying shoes from another country means decoding a different sizing system, and a US 9 is not a UK 9 or an EU 9. This converter translates a shoe size between US, UK, EU, and centimeter scales, with separate formulas for men, women, and kids.
Online shoppers use it when a store lists only one region's sizes, travelers use it abroad, and parents use the kids setting for fast-growing feet. By converting through the underlying foot length in centimeters, it keeps the cross-region results consistent rather than relying on a rough lookup.
How to Use the Shoe Size Converter
- Select the wearer: men, women, or kids.
- Enter a size and choose which region it is in (US, EU, UK, or CM).
- Read the equivalent sizes in all the other systems.
- Use the centimeter figure as the most reliable cross-check when buying online.

Frequently Asked Questions
Why isn't a US size the same as a UK size?
The US and UK scales start counting from different points, so the same foot maps to different numbers — a US men's size is roughly half a size larger than the UK equivalent. EU sizing uses an entirely different scale based on length. That is why a converter is needed.
Which measurement is most reliable for ordering online?
The centimeter measurement of your foot length is the most dependable, because it does not depend on a brand's interpretation of a size number. Measure your foot, convert here, and compare against a retailer's size chart in centimeters when possible.
Do men's and women's sizes really differ?
Yes. For the same foot length, men's and women's size numbers differ by roughly one and a half sizes in the US system, which is why this converter asks you to select the wearer before converting.
Are converted sizes exact across every brand?
No conversion is perfect, because brands cut shoes differently and some run large or small. Use the result as a strong starting point, then check the specific brand's size guide and reviews, especially when you cannot try the shoes on.
