International Shoe and Clothing Sizes
US, UK and EU sizing numbers are labeling systems, not measurement units. Conversions can differ by brand, category and gendered size range.
Mr. 360 says: Converting 270 mm to 27 cm is exact. Calling it a specific EU or US shoe size without a brand chart is not.
Foot-length measurement converter
Place your heel against a wall, stand on paper, mark the longest toe, and measure both feet. Follow the brand's instructions for any fit allowance.
What clothing region labels tell you
| Label | What to check |
|---|---|
| US | Men's, women's or youth size; relevant garment measurements |
| UK | Category-specific size chart and measurement definitions |
| EU | Whether the brand uses EU/FR/IT conventions, especially for apparel |
| JP / CN | Actual garment or body dimensions in centimeters rather than assumed letter equivalences |
Buying with fewer surprises
- Record your body or foot measurement, not just a familiar size label.
- Select the precise product and category on the manufacturer's chart.
- Verify whether measurements reflect the body, footbed, or finished garment.
- Consider fit allowance, shape and return policies.
