Shoe size converter for men and women [US, UK, EU, CM, inches]
NOTE: This conversion is based on the average measurements across brands. Your actual size may vary depending on these factors:
- Shoe brand. Manufacturers are not aligned on how they size their shoes. That’s why you may need size 9 in Adidas and size 10 in Nike. Once you know what brand you’ll be purchasing from, we recommend checking your size using the tool below.
- Your foot measurements. One millimeter is enough to take you from one size to another. Having your exact foot length and width measured before shopping online will increase the chances of getting the accurate size.
Because there is no uniform standard of shoe sizing across all manufacturers, no one can tell you precisely how one size converts to another. But the good news is that there are some common tendencies.
UK to US
The UK sizing scheme does not differentiate men’s and women’s sizes, but the US one does:
EU to US
The intervals between EU sizes are smaller than those in the US scheme. That’s why one US size may be equivalent to two or even three different EU sizes.
Knowing your exact foot length in centimeters/inches will help to determine the more accurate EU size for you:
|CM||US men||US women||EU|
Because there is no simple formula for converting EU size to US, we recommend using the conversion tool above.
CM / Mondopoint to US
The CM marking is the most no non-sense sizing scheme available today. It’s number simply indicates the foot length in centimeters:
This system is also referred to as Mondopoint. It was developed by the ISO (International Organization for Standardization) in the 1970s as an attempt to simplify conversions between US, UK, and EU sizes.
Because it is commonly used by manufacturers in China, Japan, and South Korea, you might as well see them presented as CN (China) or JP (Japan).
The sizes in this system have intervals of 5 mm: 22, 22.5, 23, 23.5, etc. Use the converter above to see the corresponding US, UK, and EU sizes.
