How it is calculated
Shoe sizes are given in different systems around the world – EU, UK, US and Japan measure in different ways. The converter works through the foot length: every size is turned into it and then passed on to all the other systems.
How the systems relate
- EU (Paris point): each size is 2/3 cm of last length – size 42 matches a 28 cm last.
- UK: one size is one barleycorn, which is 1/3 inch. Size 8 sits at an 11 inch last.
- US: men’s sizes are 1 larger than UK, women’s sizes another 1.5 larger than men’s.
- Japan: the size is the foot length in centimeters. The Mondopoint system (ISO 9407) likewise gives the foot length, in millimeters.
Between foot length and last the converter adds 1.5 cm of allowance so your toes have room in the shoe. Example: a 26.5 cm foot leads to EU 42, UK 8, US 9 (men’s) or 10.5 (women’s).
Measure your foot properly
Measure in the evening, when the foot is largest, standing, from the heel to the longest toe, and use the larger foot. The measurement in centimeters can be entered directly as the starting value. For inches and centimeters use the length converter and the inch to cm converter; for measuring on screen there is the online ruler.
Frequently asked questions

How do you convert US shoe sizes to EU?
For men’s sizes UK = US − 1, and the EU size follows from the last length: US 10 is about EU 43. For women’s sizes US is about 2.5 larger than UK.
How do I measure my shoe size correctly?
Stand on paper in the evening, measure from heel to the longest toe and use the larger foot. Enter the number in cm as the starting value.
Why do shoes from different brands fit differently?
Because lasts, patterns and materials differ. The calculated conversion is a guide; the manufacturer’s size chart comes first.
Does the conversion work for children’s shoes?
No. Children’s sizes are counted differently (for example the UK children’s scale starts at 0). This converter is meant for adult sizes.
