How accurate are international shoe size conversions?

Charts give a reliable starting point, but sizing differs by brand and shoe style. For the best fit, measure your foot length in centimetres and match that column.

What is the difference between US men and US women shoe sizes?

US women's sizes run about 1.5 sizes larger than US men's for the same foot, so a US Men 9 is roughly a US Women 10.5. This tool shows both.

Is my data sent anywhere?

No. The conversion chart is built into the page and runs entirely in your browser.

How do I measure my foot length in centimetres?

Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe, and measure from the wall to the mark in centimetres. Match that to the cm column for the most reliable size.

What is a US Men 9 in EU and UK?

A US Men 9 is roughly an EU 42.5 and a UK 8.5, corresponding to about 27.0 cm of foot length. Brands vary, so treat this as a starting point.

Are EU shoe sizes the same for men and women?

Yes. EU sizing is unisex and based purely on foot length, so the same EU number is used for men's and women's shoes of the same length. US and UK systems split by gender.

International shoe size converter

Shopping for shoes from another country? This converter lines up US Men, US Women, UK, EU and foot length in centimetres so you can find your size in any system. It is for international online shoppers translating a size from one region’s labelling to another’s.

How it works

The tool uses a fixed adult conversion chart anchored to foot length in centimetres (mondopoint). You choose the system you already know and enter your size; it finds the chart row whose value is closest to your input and reads the matching size in every other system. Because the chart is length-based, the cm column is the most reliable reference when systems disagree.

US women’s sizes run about 1.5 sizes larger than US men’s for the same foot, so a US Men 9 sits alongside a US Women 10.5 on the same row.

Example

A US Men’s 9 lines up as follows:

System	Size
US Men	9
US Women	10.5
UK	8.5
EU	42.5
Foot length	27.0 cm

Sizing varies by brand and last shape, so measuring your foot length and matching the cm column is the most reliable approach. Everything runs in your browser — no measurements ever leave your device.
