How do US, UK and EU shoe sizes line up?
Two fixed charts sit behind the converter. The men's chart runs from US 6 to US 13 in half sizes, with no 12.5 row, and the women's chart from US 5 to US 11; children's sizes are not included. In the men's chart UK is always half a size below US, so US 9 equals UK 8.5, EU 42.5 and a 27 cm foot. Women's sizes work differently: UK sits two sizes below US, so UK 5 equals US 7, EU 37.5 and a 23.8 cm foot. The full table under the result highlights the matched row.
EU numbers move at a different pace because the systems count in different units. UK and US sizes rise by one barleycorn, a third of an inch or about 8.5 mm, per full size, so a half size adds about 4.2 mm. EU sizes rise by a Paris point of two thirds of a centimetre, about 6.7 mm. A US half size is therefore worth a little more than half an EU size, which is why the EU column sometimes jumps a whole number: men's US 8 is EU 41, and US 8.5 is EU 42.
What if your size falls between rows or off the chart?
The tool highlights the row within 0.25 of what you type. When no row is that close, it picks the nearest one, and a tie goes to the smaller size, so a men's EU 41.5 resolves to EU 41, US 8. A men's foot length of 26.3 cm also lands on the 26 cm row, which is shorter than the foot, so check the next row up as well. Sizes beyond the chart snap to the end rows without a warning: men's US 14 shows the US 13 row and women's US 12 shows US 11. Type half sizes with a decimal point, since 9,5 is read as 9.
Foot length is also the way to cross between the men's and women's charts. A women's US 9 is listed at 25.4 cm. Switch to Men, choose Foot length (cm), enter 25.4, and the men's chart returns US 7, UK 6.5 and EU 40. Measure both feet and work from the longer one. For clothing, the Clothing Size Converter covers US, UK, EU, India and letter sizes.
