Tool Introduction

Estimate shoe size from foot length and compare the sizes shoppers most often see in the United States, United Kingdom, Europe, and Japan. Choose women, men, or kids, switch between centimeters and inches, and copy the result for a product page or size note.

The conversion is based on foot length and Mondopoint-style measurement, which ISO 19407:2023 identifies as the logical starting point for shoe size conversion tables. Shoe brands still vary, so use this as a reliable shopping estimate and confirm against the seller's chart before ordering.
