Shoe Size Converter
Convert adult sizes between BR, US, UK, EU and JP with a practical reference table.
Use this shoe size converter to compare adult sizes across Brazil, the United States, the United Kingdom, Europe and Japan without hunting through separate charts. Enter the size you have, choose the source system and see the closest equivalent across the main standards.
This is useful for online shopping, imported footwear, travel and comparing sizing across brands. The result is a quick reference, but the official brand chart is still the safest check when the shoe last or insole length runs smaller or larger than usual.
Use clear inputs to get a more useful result.
How to use Shoe Size Converter
