How it works

Two steps, no account

1

Pick the system you know

Whatever's printed inside your shoe or on the box — EU, UK, US, Japanese, or a raw centimeter measurement.

2

Read every equivalent at once

All 14 systems convert through a common EU-size baseline, so you only ever have to enter one number.

FAQ

Common questions

How accurate are these conversions?
Shoe sizing isn't perfectly standardized between brands and countries, so treat these as a close estimate rather than an exact guarantee — brand-specific size charts are more reliable when you have one.
What's Mondopoint?
A sizing system based directly on foot length in millimeters, used across several countries and by some athletic and military footwear — it's the most literal of the systems here, since it's just a measurement rather than a size-label scale.
Is my data sent anywhere?
No. The conversion runs entirely in your browser — nothing is transmitted, logged, or stored.
