Shoe Size Converter
Compare shoe sizes between EU, UK, US men, US women, kids, Mondopoint and measured foot length.
Recommendation
Shoe sizes are not fully standardised across countries or brands. Results are general recommendations. Always check the manufacturer’s size chart and measure both feet before buying.
Mapping applies roughly to 265.0-268.4 mm.
Measured foot length, not a manufacturer's CM label or insole length.

Good to know
Good to know
The shoe size converter converts directly in your browser between EU/UK, US, Japan, and Mondopoint — starting from either a known size or a measured foot length, separated into adult and child profiles. A measuring guide explains how to correctly determine foot length.
Typical searches include EU to US shoe size, UK to EU, and convert shoe size. Calculation runs locally in the browser. Important: shoe sizes are not fully standardized worldwide or across brands — the result is a general recommendation. Always check the manufacturer's size chart before buying and measure both feet.
Typical use cases
Convert shoe size for international orders
Convert a known EU, UK, or US size when ordering from a foreign retailer.
Determine size based on measured foot length
Measure the foot length following the guide and enter it directly when no known size is available as a starting point.
Convert children's sizes between systems
Use the child profile to correctly convert children's shoe sizes between EU, UK, US, and Mondopoint, instead of applying the adult scheme.
Tips for better results
Always check the manufacturer's chart too
Since brands, lasts, and foot width can differ even at the same nominal size, the result is a recommendation — the manufacturer's own size chart is more authoritative before buying.
Measure both feet and use the longer one
Feet are rarely exactly the same length — measure both and use the longer value, wearing the socks worn in the shoe.
