What is a Shoe Size Converter?
A shoe size converter translates shoe sizes between the international sizing systems used in different countries — US, UK, EU, and foot length in centimeters. Because each system was developed independently with different scales and starting points, converting between them is essential when shopping internationally or comparing sizes across brands.
How to Use
- Select your gender (Men, Women, or Kids).
- Choose the sizing system your size is in (US, UK, EU, or CM).
- Enter your size. All equivalent sizes in other systems are shown instantly, along with a full size chart.
Frequently Asked Questions
Why are shoe sizes different in different countries?
Shoe sizing systems developed independently. US/UK sizes use barleycorns (1/3 inch) with different starting points. EU sizes use Paris points (⅔ cm). Japan uses foot length in cm. There's no universal standard, requiring conversion charts.
Do men's and women's shoe sizes differ?
Yes. US men's and women's sizes differ by about 1.5 sizes — a men's 9 is roughly a women's 10.5. UK and EU sizes are generally unisex. When shopping internationally, always check which gender sizing the retailer uses.
How do I measure my foot size at home?
Trace your foot on paper, measure from heel to longest toe in cm. Add 0.5–1 cm for comfort. Measure both feet (they often differ) and use the larger measurement. Measure in the afternoon when feet are slightly swollen.
What is half a shoe size equivalent to in mm?
In EU sizing, each full size = ⅔ cm (6.67 mm). In US/UK sizing, each half size = ⅙ inch (4.23 mm). When between sizes, always size up — shoes that are too tight cause blisters and foot problems more quickly than shoes slightly too large.
