Convert shoe sizes between US, UK and EU sizing systems.
This is an approximate conversion for general informational purposes only. Shoe size conversions vary by brand and by category (men’s, women’s, children’s) — always check the specific brand’s size chart when possible, especially before purchasing.
Shoe sizing systems differ by country and are based on slightly different measurement traditions, so conversions between US, UK and EU sizes are approximate rather than exact — brands can also vary slightly in their own size charts.
Example

Frequently Asked Questions
Is this conversion exact?
No — shoe size systems are not perfectly standardized across countries or brands, so this is a commonly used approximation rather than an exact conversion.
Does this work for women’s sizes?
This calculator uses men’s sizing conventions; women’s US-to-EU/UK conversions typically use a different offset, so check a brand’s specific women’s size chart for accuracy.
