How to convert a US shoe size to EU
Choose the sizing scale and enter the US size.
1
Pick men’s or women’s
The two scales use different offsets, so the choice changes the result.
2
Enter the US size
Half sizes are supported and keep the result on the same scale.
3
Check foot length
Compare the centimetre estimate with the brand’s chart for the best fit.
What does this tool do?
US, UK and EU shoe charts are offset differently, and the gap depends on the width of the size step. This converter applies the common retail offsets and shows the approximate foot length.
The Formula
EU = US + 33 (men) or US + 31 (women); UK = US − 1 (men) or US − 2 (women); foot length ≈ EU ÷ 1.5 − 1.5 cmFrequently Asked Questions
What is a US men’s 9 in EU?
About EU 42 and UK 8. The foot length is roughly 26.5 cm, but brands can vary by half a size.
Do women’s and men’s sizes convert the same way?
No. Women’s US 8 is about EU 39, while men’s US 8 is about EU 41, because the two size scales start at different points.
