Shoe Size Converter: EU, UK, US, Japan, cm

How to use it

In the "Convert a size" tab, choose the system you know (for example EU) and enter the size. The table instantly shows the equivalents: EU, UK, US men's and women's sizes, foot length in centimetres and inches, and Mondopoint (millimetres). Sizes are rounded to the nearest half size.

• Foot length: stand on a sheet of paper, mark the heel and the tip of the longest toe, and measure the distance between the marks.
• In the "From foot length" tab, enter the measured length to get suggested sizes with a 0.5–1 cm comfort allowance.
• Measure in the evening when feet are slightly swollen, and measure both feet, as they often differ.

How it is calculated and why sizes differ

The tool uses a common adult size chart (foot length from 22.5 to 28.5 cm). Values between rows are linearly interpolated, so in-between sizes do not rely on one fixed formula. Outside the chart, it says that no exact equivalent exists.

This is only a guideline. Brands use different lasts, and men's, women's and children's size scales differ. Children's sizes are not included here. When shopping online, check the specific brand's chart and the size reviews.
