How to convert a women’s US size to EU
Add 32 for the EU label and 4 for the UK label.
1
Enter the US size
Use the numeric size on the label, not the letter size.
2
Read the EU size
US 8 becomes EU 40 under the common retail mapping.
3
Adjust for the brand
If reviews say the style runs small or large, move one EU size up or down.
What does this tool do?
Women’s US numeric sizes convert to EU labels with a 32-point offset, and UK sizes sit four points above the US number. Brand sizing varies, so treat the result as a starting point.
The Formula
EU size = US size + 32; UK size = US size + 4Frequently Asked Questions
What is a US 8 in EU sizing?
US 8 + 32 = EU 40, which is usually UK 12. Some brands label the same fit as EU 38, so check their own chart.
Why do EU sizes differ between shops?
There is no single enforced conversion. Vanity sizing and different fit blocks mean the same label can measure differently.
