Result
Here the shoe size converter loads with UK preset as the source system and US as the target: select the category, enter your British size, and the American size is shown immediately with the matching EU, JP and centimetre values in the same row.
UK and US sizes use the very same barleycorn step of a third of an inch, but the scales are offset: a men's US size is typically the UK size plus 0.5, while a women's US size runs about 2 sizes above the UK number — UK 6 is a women's US 8. The offset is consistent on paper; actual shoes are not, and different brands can fit up to half a size apart, as the tool notes with every conversion.
This is the complete converter, simply preconfigured for this pair. Switch to kids' sizes, reverse to US-to-UK, or enter a measured foot length in cm — the static charts are bundled in and everything is computed locally in your browser, with no uploads and no sign-up.
