Convert shoe sizes between US, UK, and EU systems for men and women. Free online shoe size converter with international size chart and FAQ.
The shoe size converter helps you convert between US, UK, and EU shoe size systems for both men and women. This is essential when shopping for shoes internationally or online, as different countries use different sizing standards. Note that sizes can vary between brands.
Men: UK = US - 1 | EU = US + 33
Women: UK = US - 2.5 | EU = US + 31.5
(Standard approximations; may vary by brand)The conversion formulas are based on standard size charts. UK sizes are typically 1 size smaller than US men's and 2.5 sizes smaller than US women's. EU sizes use a different numbering system entirely. These are standard approximations and actual fit may vary by manufacturer.
