Shoe Size Converter
Convert common shoe sizes across regions, then check the details that actually determine comfort.
Use your usual size as the starting point. Length alone does not account for width or the shoe last.
Choose the region printed on the shoe size you already know.
Use the recommendation as a styling direction. Fabric, fit, comfort, culture, occasion and personal taste can change the best choice.
Use the interactive guide below as a private starting point. No measurement is stored or submitted by this calculator.
Measure both feet near the end of the day and use the larger foot as your reference. Width, toe shape and brand fit still matter after conversion.
Turn a shoe conversion into a comfortable choice
Regional shoe conversion gives you a useful starting point, but comfort is controlled by more than length. Width, toe shape, instep volume, heel height and the brand’s last all affect how a shoe behaves.

Feet can change throughout the day. Measure both feet when they are naturally expanded and use the larger foot as your reference.
Check length and toe room
Your longest toe should have comfortable room in front. Your forefoot should sit inside the shoe’s widest part without being squeezed from the sides.
Think about the shoe last
A pointed toe, rounded toe and square toe can all have the same nominal size while feeling completely different. A correct length can still be a poor fit if the toe box is wrong for your foot.
Use the result with the retailer chart
When a retailer publishes insole length, width or half-size guidance, use that information alongside the regional conversion.
Fit note: a shoe that hurts before it “breaks in” is usually giving you useful information about fit, not a challenge to tolerate.
Frequently Asked Questions
Is the converted shoe size guaranteed to fit?
No. Width, toe shape, last construction and half-size availability can change the fit even when the regional number matches.
Which foot should I measure?
Measure both and use the larger foot as the reference. Feet often change size slightly through the day.
Why can the same size feel different?
Shoes from different brands can use different lasts, widths and upper materials, so length is only one part of comfort.
