Shoe Size Converter: UK, US, and EU Sizes Explained
Shoe sizes look like numbers, but each system counts differently. The men's conversions are simple: US runs one above UK, and EU runs 34 above UK.
What is the Shoe Size Converter?
Enter a men's shoe size and convert it between UK, US, and EU systems with standard conversions: US men's is one larger than UK, and EU is UK plus 34. Sizing varies by brand and by foot shape, so treat the result as a starting point and check the brand's own chart before ordering.
How to use it
- Enter the shoe size.
- Choose the system it is in.
- Choose the system to convert to and click Convert Shoe Size.
Worked example
A men's UK size 8 converts to US 9 and to EU 42, since US equals UK plus 1 and EU equals UK plus 34.
Why do converted sizes sometimes not fit?
Because brands shape their shoes differently and feet differ in width, so a converted size is a starting point, not a guarantee.
Frequently asked questions
Are women's sizes the same?
No. Women's US sizes run differently from men's, so this converter covers men's sizing only.
What about half sizes?
They convert the same way: a UK 8.5 becomes a US 9.5 and an EU 42.5 on these standard conversions.
