Frequently Asked Questions

How do I convert between shoe size systems?

EU 40 approximately equals US men's 7.5 / UK 6.5 / foot length 25.3 cm. EU 37 approximately equals US women's 6.5 / UK 4. Always measure your actual foot length for the most reliable conversion.

How do I find my correct shoe size?

Measure your foot length in centimeters at the end of the day (feet swell). Add 1-1.5 cm for toe room. Use the brand's specific size chart, as sizing varies between manufacturers.

How precise is the conversion?

Conversion factors are based on official SI units or internationally accepted standards. Precision is at least four decimal places — sufficient for everyday, professional and academic use.

Step-by-Step Guide

How to use the shoe size converter step by step: 1. Choose the type of input -- EU size, UK size, US size or foot length in cm. 2. Choose gender/category -- men, women or children, since the sizing systems are scaled differently. 3. Enter the value -- the calculator shows the size in all systems. 4. Measure your foot length: place your foot on a sheet of paper, mark the longest point (heel to longest toe) and measure it. It is best to measure in the afternoon, since feet swell over the course of the day. 5. Important conversions: EU 40 = UK 6.5 = US men 7.5 (about 25.5 cm). EU 38 = UK 5 = US women 7 (about 24.5 cm). 6. Allow some room: the shoe should be about 10-15 mm longer than the foot. Tip: measure children's feet regularly, as they grow about 1-2 sizes per year.
