FAQ

Frequently asked questions

Quick answers to common questions about the Shoe Size Converter.

What does the Shoe Size Converter do?

It converts a shoe size between the US, UK and EU sizing systems, or from a measured foot length in centimetres, for men's or women's sizing.

Is the Shoe Size Converter free to use?

Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.

Is my input safe when I use this tool?

Yes. The size or measurement you enter is processed entirely on your own device — nothing is sent to a server.

Why does it ask for men's or women's sizing separately?

The same numeric size (like a "9") corresponds to a different actual foot length depending on whether it's a men's or women's size, so keeping them separate gives an accurate conversion instead of a mismatched one.

Can I convert from a foot measurement instead of a size?

Yes. Choose "Foot length (cm)" as the size system, enter your measured foot length, and the converter gives you the equivalent US, UK and EU sizes.

How accurate are the converted sizes?

They're based on standard sizing charts, which are consistent across most brands but can vary slightly by manufacturer — treat the result as a close approximation rather than an exact fit guarantee.

Can I use the Shoe Size Converter on my phone?

Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.

Does the Shoe Size Converter have any limitations?

It covers standard adult men's and women's sizing; it isn't built for specialized children's sizing charts or brand-specific size runs.
