How to Measure Your Foot
Step-by-Step Measurement Guide
- Prepare: Wear the socks you plan to wear with the shoes
- Stand: Place your foot flat on a piece of paper, standing upright
- Mark: Mark the longest part of your foot (usually big toe to heel)
- Measure: Use a ruler to measure the distance in centimeters
- Compare: Use the cm column in the charts above to find your size
- Repeat: Measure both feet and use the larger measurement
Important Sizing Notes
- Brand variations: Sizes can vary between brands and styles
- Width matters: These charts show standard width. Wide or narrow feet may need adjustments
- Measure both feet: Feet are often slightly different sizes
- Time of day: Feet swell during the day - measure in the afternoon
- Half sizes: If between sizes, go up for comfort
Understanding Size Systems
US Sizing: Uses different scales for men and women. Based on the barleycorn unit (1/3 inch).
UK Sizing: Similar to US but with a different starting point. Generally 1-2 sizes smaller than US.
European Sizing: Based on the Paris point (2/3 cm). More uniform across men's and women's shoes.

- Read customer reviews about sizing (runs small/large)
- Consider the shoe type (athletic shoes often fit differently than dress shoes)
- When ordering online internationally, double-check the size system
- Keep in mind that children's sizes use different scales
