About this tool
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.
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.
