Shoe Size Converter
Shoe sizes vary significantly across countries and between brands. The United States uses one system for men's and women's sizes (with women's sizes roughly 1.5 to 2 sizes larger than men's for equivalent foot lengths). The United Kingdom uses a different system. Most of Europe uses EU sizes based on the Parisian Pointure system. Converting between these systems is essential for international shoe shopping, particularly online. This reference table provides approximate conversions for adult shoe sizes from US men's, US women's, UK, and EU systems, along with foot length in centimetres. These are general guidelines; fit depends on brand-specific lasts, materials, and construction. Always check brand-specific size guides and try shoes before purchasing when possible. Sizing systems have minor regional variations; use this table as a starting point and verify with the specific retailer.

Shoe size converter: frequently asked questions
How do I find my US shoe size?
Measure your foot length in centimetres from heel to longest toe. Use this measurement to find your size in the conversion table. For fitting, measure in the afternoon when feet are slightly swollen. Shoe sizes vary between brands; always try shoes before purchasing when possible.
How do US women's and men's sizes differ?
US women's sizes are approximately 1.5 to 2 sizes larger than men's sizes for the same foot length. For example, a man's size 10 is roughly a woman's size 11.5 to 12. Always check the specific gender size when ordering shoes.
How do UK and US sizes relate?
UK men's sizes are 0.5 to 1 size smaller than US men's sizes for the same foot length. UK women's sizes are 2 to 2.5 sizes smaller than US women's sizes. Always verify the specific conversion for men or women.
What is the EU shoe size system?
EU sizes are based on the Parisian size system and apply across Europe. EU men's shoe sizes roughly equal US size plus 33. EU women's sizes vary; a US women's 7 is approximately EU 37-38. Different regions (Italy, France, UK) use slightly different size systems, so always check.
Why do shoes fit differently between brands?
Shoe fit depends on brand-specific lasts (the foot-shaped molds used to make shoes), materials, and construction methods. A size 10 in one brand may not fit the same as size 10 in another. Width, heel height, and toe box shape also vary. Always try shoes or check brand-specific size guides.
Notes
Shoe sizes vary significantly between manufacturers and brands. These conversions are general guidelines based on standard sizing systems. Always consult brand-specific size guides and try shoes before purchasing when possible. Regional and gender-specific differences apply.
