Shoe Size Converter
Compare the shoe sizing systems people actually see on product pages and boxes: EU, US men's, US women's, UK, Japan in centimeters, Korea in millimeters and Mondopoint. Use foot length as the cleanest common reference.
Reference matched to the nearest standard foot length entry. Use this as a buying guide, then confirm brand-specific fit and width.
Quick reference table
Most global marketplaces mix at least three different systems on one page. That is why foot length is the safest anchor. This table maps the major consumer formats most people see worldwide.

Why this conversion matters
Shoe sizes are one of the messiest conversion jobs in retail because size labels are short, widths vary and brand fit is inconsistent. A fast converter helps when you are buying online from another region, comparing resale listings, checking sneaker drops, or ordering work shoes and sports footwear from international stores.
The most practical way to cut through the noise is to anchor the comparison to foot length. That is why this tool exposes Japan in centimeters and Korea in millimeters alongside EU, US and UK labels. Those length-based systems are much easier to reason about than guessing whether one country's size 9 behaves like another country's size 9.
Typical use cases
- Buying trainers from US or Japanese shops while you usually buy in EU sizes.
- Checking imported work boots, football boots or running shoes before you order.
- Comparing resale or marketplace listings where the seller uses a different regional size system.
- Double-checking a gift purchase when the brand page lists size in centimeters rather than UK or EU numbers.
Practical guidance
Use this converter as a fast reference, then check the brand's own fit notes. Material, width, last shape and intended use still matter. A leather boot, a narrow dress shoe and a cushioned running shoe can all behave differently at the same nominal size.

This converter is commonly used when comparing shoe sizes across different countries and brands. It is especially useful before ordering footwear from another market or checking brand sizing tables.
Common use cases

Shoe sizing differs between regions and brands, so a practical comparison tool helps narrow down the correct size range quickly.
These tools are designed for real-world use and provide instant, reliable results.
Which systems are covered?
This page covers the major consumer systems most people run into worldwide: EU, US men's, US women's, UK, Japan in centimeters, Korea in millimeters and Mondopoint.
Why can the same size still fit differently?
Brands use different shapes, widths, materials and intended fit. The converter gives you the best cross-system reference, but not a guarantee of comfort.
What should I trust most when shopping online?
Foot length in centimeters is usually the cleanest shared reference when you compare international sizing charts.
Why this result matters in practice
A conversion only becomes useful when it helps with the real decision behind it. That may be ordering the right part, choosing the correct setting, estimating remaining material, reading a specification sheet properly or avoiding a bad assumption caused by mixed unit systems.
The safest workflow is simple: convert once, note the result, and keep the rest of the task in the same system. That prevents the small repeated rounding mistakes that turn into incorrect dimensions, wrong settings or poor buying decisions.
Practical follow-up checks
- Confirm whether the source uses metric or imperial units consistently
- Check whether the value needs rounding or exact precision
- Keep the rest of the calculation or project in one unit system
- Use a related converter when the task includes a second measurement step
