Quick answer

A shoe size converter gives a close match between UK, US, EU and centimetre sizes. It is useful when shopping internationally, but fit can still vary by brand, width and shoe shape.

Fit warning: Use the brand’s own chart if possible. Trainers, boots, dress shoes and children’s shoes can fit differently even with the same label size.

How shoe size conversion works

This converter uses common lookup tables. Adult men’s, adult women’s and children’s sizes are handled separately because US size systems differ.

UK sizesCommon in the UK and often used by UK retailers.
US sizesMen’s, women’s and kids’ US labels are not the same.
EU sizesOften used across Europe and on many international shoe labels.
CentimetresA foot-length guide, useful when measuring at home.

FAQs

Is a UK shoe size the same for men and women?

UK adult shoe numbers are often similar, but fit and width can still vary by brand and style.

Why are US men’s and women’s shoe sizes different?

US systems label men’s and women’s shoes differently, so the same foot length may have different US numbers.

Should I size up or down?

Use the retailer’s fit notes. Some shoes run narrow, wide, small or large compared with the label.
