Why are UK and US shoe sizes different?

UK and US shoe sizing systems use different starting points and increments. US men's sizes are typically 0.5 larger than UK sizes, while US women's sizes are 1.5 larger than UK sizes. Children's conversions vary by age group.

Is the conversion the same for all shoe brands?

The conversion table reflects the standard industry sizing. Some brands have minor variations in fit due to last design, so it is always worth checking a brand's specific size guide when available.

What if my UK size falls between two US sizes?

Half sizes are included in this converter. If your exact UK size is not shown, round to the nearest half size and compare, or try both the size above and below.

Do UK women's and men's sizes differ from US by the same amount?

No. Men's UK to US conversion adds 0.5 (e.g. UK 9 = US 9.5). Women's conversion adds 1.5 (e.g. UK 6 = US 7.5). Always select the correct gender for an accurate result.

Are children's sizes handled separately?

Yes. Children's UK shoe sizes (typically 1–13 in little-kids, then 1–6 in big-kids) convert differently from adult sizes. Select "Children" to use the correct table.
