About Shoe Size Converter
Shoe Size Converter is a free, ad-supported tool for converting shoe sizes between the US/Canada, UK, Europe, Japan/Mexico and China systems, plus raw inches and centimetres measurements.
Who runs this site
Shoe Size Converter is built and maintained by Loqui Ltd. The site was created because shoe size charts scattered across retailer websites are frequently inconsistent, cluttered with unrelated content, or missing the systems a shopper actually needs — the goal here is a single, fast, accurate reference with no account, no app download, and no unnecessary friction.
Where the conversion data comes from
Every size correspondence used by the converter and the size guides is built around foot length in centimetres, the common physical measurement that every named sizing system is ultimately derived from. The reference tables are cross-checked against publicly published sizing standards, including Wikipedia's shoe size reference and industry conversion charts such as Calculator.net's shoe size conversion tool. Because individual brands and styles vary in their own sizing, every guide on this site includes the same disclaimer: treat conversions as a reliable starting point, and check the maker's specific chart when precision matters.
How the site is funded
Shoe Size Converter is free to use and supported by advertising. No account, subscription or payment is required to use the converter or read the size guides.
