Shoe Size Conversion Reference
These conversions use commonly referenced size charts. Sizing can vary somewhat between brands and even between different shoe styles from the same brand, so use this as a helpful starting point — trying on shoes or checking a specific brand's size chart is recommended for the most accurate fit.
Worked Example
UK size: approximately 9.5
EU size: approximately 44
Foot length: approximately 28 cm
Understanding Your Results
US, UK, and EU sizing systems all use different scales and starting points, so direct conversion isn't a simple offset — this calculator uses standard reference tables for men's and women's sizing separately, since they follow different scales.
Frequently Asked Questions
EU sizes generally run about 32-33 points higher than US men's sizes on the standard scale (e.g., US 10 ≈ EU 44) — this calculator handles the conversion automatically using standard reference charts.
Yes — men's and women's US sizing use different scales, so a 'men's size' and 'women's size' aren't directly comparable numbers even within the same sizing system.
There's no single universal manufacturing standard, so brands and even individual shoe styles can size slightly differently — checking specific brand size charts or trying shoes on is recommended for critical fit.
It provides a reasonable general estimate, but actual foot shape, width, and brand-specific fit all affect true comfort beyond just length.
When in doubt, and especially when ordering online without trying on first, sizing up slightly is often safer, but check the specific retailer's size guide when available.
