Shopping from an international retailer? This free shoe size converter turns a US size into its EU, UK and centimeter equivalents so you can order with more confidence.
Sizing formulas are approximate general conversions – actual fit varies by brand. When possible, check the brand’s specific size chart.
What This Shoe Size Converter Shows You
A shoe size converter translates a US shoe size into its approximate EU, UK, and centimeter foot-length equivalents, useful when shopping international brands or reading size charts from other regions.
Why Sizing Systems Differ So Much
The US, UK and EU each developed shoe sizing independently, using different reference points and scales – which is why the same physical foot length maps to different numbers across systems.
Why Brand Still Matters More Than Conversion Alone
Even within one sizing system, fit varies by brand and shoe style – a size 10 running shoe and a size 10 dress shoe from different brands can fit noticeably differently. Conversion gets you close; the brand’s own chart gets you exact.
Measuring Your Foot Directly
For the most reliable result, measuring your actual foot length in centimeters and comparing it to a specific brand’s size chart is more accurate than converting between size systems alone.
