Measuring
Foot Length to Shoe Size Chart
Foot length is one of the best ways to choose a shoe size online because it gives you a measurement to compare against brand charts instead of relying only on region labels.
Why centimetres help
UK, US and EU sizes are naming systems. Foot length in centimetres is a measurement, so it is often easier to compare across international retailers.
Japan sizing is commonly shown in centimetres, which makes it a useful cross-check when a product page lists JP or cm sizing.
How to use your foot length
Measure both feet while standing, use the larger foot, then compare that measurement with the size chart for the category you are buying.
- Adults: compare against the men’s or women’s chart.
- Kids: leave suitable growing room rather than matching the foot exactly.
- Wide feet: confirm width before sizing up in length.
Common questions
Is foot length more accurate than UK or EU size?
It is often a better starting point because it is a direct measurement, but brand shape and width still affect fit.
Should I use centimetres or millimetres?
Either works. Centimetres are common in Japan sizing, while millimetres are common in Korea sizing.
