Shoe Size Converter
Convert men's and women's shoe sizes between US, UK, EU and International (foot-length in cm) sizing references, or estimate a size from your foot length. Use the guide as a starting point and always compare with the shoe brand's own chart.
Convert a shoe size
Choose the size chart, the sizing system you know, and your current shoe size. Matching sizes appear instantly when you convert.
International (cm) shows the foot-length reference used by this chart. These are approximate equivalents. Fit can vary by brand, shoe shape and width.
Find my size by foot length
Measure from the back of your heel to the tip of your longest toe. Measure both feet and use the longer measurement.
Length-based results are estimates from a general conversion guide, not a guarantee of fit. If you are between sizes, check the brand's fit advice.
How to measure your foot
1. Place paper on the floor: Put a sheet of paper against a wall on a hard, level surface.
2. Stand naturally: Place your heel against the wall and stand with your full weight on the foot.
3. Mark your longest toe: Mark the tip of your longest toe, then measure from the wall edge to the mark.
4. Measure both feet: Feet can differ in length, so use the longer measurement. Measure later in the day for a realistic fit check.
5. Consider width: Foot length is only one part of fit. Check whether the brand offers narrow, regular or wide widths.
Shoe size converter FAQs
How does the International (cm) size work?
US, UK and EU use different regional sizing scales. International (cm) in this tool displays the foot-length reference in centimeters; it is not a single universal brand size.
Should I measure my foot in the morning or evening?
Measure later in the day when your feet may be slightly larger. This can help you avoid choosing a size that feels too tight.
Why can the same shoe size fit differently between brands?
Brands can use different lasts, shapes, width allowances and size grading. Always check the specific product's size chart when available.
What if my measurement falls between two sizes?
Use the brand's guidance for that shoe style. Consider the intended use, socks and width, and choose the option that gives your toes enough room.
