About This Calculator
The Shoe Size Conversion Calculator helps you convert shoe sizes between different sizing systems: US, EU (European), UK, and CM (centimeters). It provides conversions for both men's and women's shoe sizes.
This tool is essential for online shopping, international travel, and purchasing shoes from different regions. The calculator uses standard conversion formulas to provide accurate size equivalents across different sizing systems.
Formula & Calculation Method
Shoe size conversions use approximate formulas:
- Men's US to EU: EU = US + 33
- Men's US to UK: UK = US - 0.5
- Men's US to CM: CM = (US + 22) × 0.847
- Women's US to EU: EU = US + 31.5
- Women's US to UK: UK = US - 2
- Women's US to CM: CM = (US + 20.5) × 0.847
Where:
- US = United States shoe size
- EU = European shoe size
- UK = United Kingdom shoe size
- CM = Foot length in centimeters
Note: Shoe size conversions are approximate and can vary by manufacturer and shoe type. It's always best to try on shoes or refer to the specific brand's size chart when possible. Half sizes and width variations can also affect fit.

Frequently Asked Questions
Are shoe size conversions accurate?
Shoe size conversions are approximate and can vary by manufacturer, brand, and shoe type. Different brands may use slightly different sizing standards. Always refer to the specific brand's size chart when possible, and consider trying on shoes when available.
Why are men's and women's conversions different?
Men's and women's shoe sizes use different scales. For example, a US men's size 10 is different from a US women's size 10. Women's sizes are typically 1.5-2 sizes larger than men's sizes for the same foot length.
How do I measure my foot in centimeters?
To measure your foot in centimeters, stand on a piece of paper, mark the longest point of your foot (heel to toe), and measure the distance. Measure both feet and use the larger measurement. This measurement in centimeters can be converted to shoe sizes.
What if my size is a half size?
Half sizes are common in US and UK sizing systems. When converting, round to the nearest whole size or use the conversion and then adjust based on the brand's size chart. Some brands may recommend sizing up or down for half sizes.
