US to EU Shoe Size Converter
Convert American shoe sizes to European sizes instantly — or start from an EU size and see the US equivalent. Both directions live on this one page.
Tip: measuring your foot in cm or inches is the most accurate starting point — see how to measure. Conversions between named size systems are approximate by nature.
How this conversion works
US and EU scales measure different things: US sizes grade in barleycorns (⅓ inch), while EU sizes use Paris points (⅔ cm) and include a functional allowance for the shoe's last. That is why no US↔EU mapping is perfectly clean — a US size covers a slightly different slice of foot length than an EU size.
Our engine converts through foot length: your US size resolves to a documented foot-length range, and the EU result is every EU size whose range overlaps it. When a US size falls between two EU sizes, both are shown — picking the larger one is usually more comfortable.

Sizes between rows are normal — the tool above shows both candidates when you land on a boundary.
Common questions
Is a US men's 9 the same as EU 42?
Very close. A US men's 9 corresponds to EU 42–42.5 in most charts. Because the two scales slice foot length differently, a boundary size can legitimately map to two EU sizes; when that happens we show both.
Do EU sizes differ between men and women?
EU sizing is nominally unisex — an EU 42 describes the same foot length regardless of gender. What differs between charts is usually the last shape, not the number.
Why do brands disagree on US to EU?
Brands grade their lasts independently; one brand's EU 42 can sit a half-size off another's. We publish the standard-scale conversion and mark every result approximate for exactly this reason — check the brand's own chart when accuracy matters.
