About This Calculator
Whether you are shopping for shoes online from international brands or traveling abroad, our free online shoe size conversion calculator helps you find the right fit across all major sizing systems. This tool converts between US Men's, US Women's, UK, EU, and foot length in centimeters and inches using internationally recognized formulas based on the barleycorn and Paris point measurement systems.
The shoe size conversion is based on foot length measured in inches. The US sizing system uses the barleycorn unit (1/3 inch per size), starting from a baseline of approximately 8.5 inches for size 0. EU sizing uses the Paris point system (2/3 cm per size). Our converter applies the standard formulas: US men's size = 3 × foot length (in) - 22, US women's size = 3 × foot length (in) - 21, UK size = 3 × foot length (in) - 23, and EU size = 3.81 × foot length (in) + 2. These formulas give mathematically consistent conversions across all systems.
How to Use This Converter
Select the sizing system you know from the dropdown menu (US Men, US Women, UK, EU, or Foot Length in cm), enter the size number, and click Convert. The calculator instantly displays the equivalent sizes in all other systems plus your foot length. You can also view a bar chart comparing the sizes and a conversion chart showing how US men's sizes map to EU sizes across the typical range.
Regional Notes
India: India follows the UK sizing system for footwear. Most Indian shoe brands use UK sizing, with EU sizing also common for sports shoes and premium brands. Use the UK system in our converter for Indian purchases. Common men's sizes range from UK 7 to UK 11 (EU 41-45).
United States: The US uses separate men's and women's sizing systems. US men's sizes are typically 1-2 sizes larger than the equivalent UK size, while US women's sizes are about 2 sizes larger than UK. Common men's sizes range from US 7 to US 14, and women's from US 5 to US 12.
United Kingdom: The UK uses a unified sizing system for men and women, though the actual fit differs. UK sizes are the most commonly used system across Europe for formal footwear. Common men's sizes range from UK 6 to UK 12, and women's from UK 3 to UK 8.
EU / International: EU sizing (also called Continental European or Paris points) is used across most of continental Europe and increasingly by global sportswear brands. EU sizes range from 35 to 50 and are not gender-specific, though women's models typically use the same EU number as men's with a narrower fit.

What is my shoe size in centimeters?
Your shoe size in centimeters is the length of your foot measured from heel to toe. To measure, stand on a piece of paper, trace your foot, and measure the distance.

Always try shoes when possible or check the brand's specific size chart. Our converter provides mathematically correct conversions based on international standards.
How do I find my shoe size if I only know my foot length?
Measure your foot length in centimeters or inches, then select Foot Length (cm) as the input system in our converter. Enter your measurement, and we will calculate your equivalent sizes in US, UK, and EU systems. A foot length of 26 cm typically corresponds to US men's 8, UK 7, or EU 41.
