Measure both feet while standing and enter the longer measurement. Width and shoe type refine the fit guidance but do not replace a brand-specific chart.

Convert a size you already know
Select the wearer, source system and known size. The result shows the nearest practical equivalents, not a brand guarantee.

Your fit profile
Recommended starting size
Equivalent size labels
Shoe sizing varies by brand, last shape, upper material and intended use. Treat this as a starting point and compare the result with the manufacturer’s own chart.
Everyday shoes
Aim for secure heel hold, comfortable toes and no pressure across the widest part of the foot.
Running shoes
Leave enough front space for foot expansion and make sure the heel does not slide while moving.
Hiking footwear
Test with hiking socks and check that toes do not hit the front on a downhill slope.
Dress shoes
A closer fit can be normal, but the toe box must not pinch and the heel should remain stable.
Why brand charts differ
US, UK and EU labels are not perfectly standardized. Two shoes carrying the same number can use different lasts, widths and internal lengths. Foot length is the best common reference, but the brand chart has the final word.
Children’s shoe sizes
Measure children’s feet regularly and avoid buying excessively large shoes for growth. The foot should be secure, comfortable and able to move naturally.

Fit guidance by shoe type
Different footwear needs different space and shape. The size stays chart-based; these tips help you judge the fit after trying the shoe on.
Shoe Size Converter FAQ
How do I convert a shoe size?
Choose men, women or children, select the known system and size, and the converter displays the nearest US, UK, EU, JP, Korean and Mondopoint equivalents.
Should I measure both feet?
Yes. Feet commonly differ slightly, so measure both while standing and use the longer foot when selecting a starting size.
What if my result falls between sizes?
Compare both neighbouring sizes. A roomier fit is often useful for running, hiking, thick socks or wide feet, but the manufacturer’s guidance should decide.
Can foot width change the recommended size?
Width does not always require a longer shoe. A wide or extra-wide version in the same length is often better than simply sizing up.
Are centimetre labels the same as foot length?
Not always. Some labels marked CM refer to a manufacturer’s size convention rather than the exact measured foot length, so compare both descriptions carefully.
How accurate is this shoe size finder?
It provides a practical starting point from a general chart. Brand shape, model, materials, socks and personal fit preference can change the best final size.
