UK vs US vs EU Shoe Sizes Explained
Shoe sizes don’t match globally because each region developed its own measurement system. Understanding how these systems work makes online shopping far less confusing.
Why Shoe Sizes Differ Around the World
Shoe sizing systems developed independently in different countries. The UK and US systems share historical roots but use slightly different scaling. The EU system uses the “Paris point” measurement. Japan often uses centimetres directly.
This is why a UK 6 does not equal a US 6, and why EU sizes often look unfamiliar.
UK vs US Shoe Sizes
For adults, US sizes are typically one size higher than UK sizes for men, and around two sizes higher for women — but this varies by brand.
Always check whether you’re looking at a men’s or women’s chart, because US sizing differs between the two.
EU Shoe Sizes Explained
EU sizes are based on a unit called the Paris point. They increase in smaller increments than UK or US sizes. Because EU sizing isn’t gendered in the same way, it can sometimes appear more consistent — but fit still varies by brand.
Japan & China Shoe Sizes
Japan commonly uses foot length in centimetres. If your foot measures 25cm, your Japan size is usually 25. This can be one of the most straightforward systems.
China sizing often resembles EU sizing but can differ slightly depending on the manufacturer.
The Most Accurate Way to Convert
The most reliable method is:
- Measure your foot in centimetres.
- Use a conversion chart.
- Check brand-specific guidance if available.
Does Width Affect Size Conversion?
Length conversion doesn’t account for width. If you regularly find shoes tight at the sides, you may need wide-fit sizing.
