How shoe sizes differ around the world
Shoe systems use different measurement scales and label conventions. The brand’s current conversion chart matters more than a guessed country offset.
Length scales differ
US and UK scales use roughly one-third-inch increments; European sizing uses the two-thirds-centimeter Paris point. These increments do not align exactly, and starting points and category conventions differ.
Metric labeling also needs context
Mondopoint uses foot measurements, but a printed CM/JP label is not proof that a manufacturer’s retail label equals measured foot length. Nike explicitly separates those values.
Fractional EU sizes are real
Manufacturers can use fractional EU labels. adidas commonly uses one-third and two-third sizes, not the half-size list sometimes copied into generic charts. Read the label as published.
Choose a chart, then verify fit
Use one product-specific chart and keep category and market consistent. A label conversion cannot determine width, instep volume or comfortable toe space.
Frequently asked questions
- Does this guidance guarantee fit?
- No. Use current product-specific measurements and an actual fit check; generic conversions are approximate.
