Shoe Size Conversion Questions
Everything you need to know about international shoe size systems and conversions
Why do shoe sizes vary between countries?
Shoe sizes developed independently in different countries based on different foot measurement studies and historical conventions. The US uses the Brannock system, the UK uses an older English system, while Europe uses a Paris point system. Each has different zero points and increments.
What's the difference between men's and women's shoe sizes?
In the US system, women's sizes are typically 1.5 sizes larger than men's for the same foot length. For example, a women's size 8 is equivalent to a men's size 6.5. This difference varies by country - the UK uses a 2-size difference while EU sizes are unisex.
How accurate are online shoe size conversions?
Size conversions provide good estimates, but actual fit can vary between brands and shoe styles. Our converter uses standard conversion formulas, but we recommend checking the specific brand's size chart and reading customer reviews for the most accurate fit.
Should I size up or down when converting between systems?
When in doubt, it's generally safer to size up slightly, especially for athletic shoes where you need room for toe movement. However, for dress shoes or boots, exact sizing is more important. Always consider the shoe type and intended use.
What does 'Japan size' mean in shoe sizing?
Japan shoe sizes represent the foot length in centimeters. For example, a Japan size 27 means the shoe is designed for a foot that is 27cm long. This makes Japanese sizing more intuitive as it directly relates to actual foot measurements.
How do children's shoe sizes convert internationally?
Children's shoe size conversions are more complex as they involve different age ranges and growth patterns. US, UK, and EU all have different children's sizing systems. Always measure the child's foot and use the brand's specific size chart for the most accurate fit.
