The European "Paris Point" System
European sizing operates on a metric basis. 1 EU size increment equals exactly 6.67 millimeters (2/3 of a centimeter).
Unlike US sizing which resets from 13C back to 1Y, EU sizing continues in a single sequence from EU 15 (baby) up to EU 40 (youth/adult).
Why Foot Length in CM is the Safest Metric
Because US and EU intervals do not divide evenly, rounding differences exist across international brands.
Measuring your child's barefoot length in centimeters and matching it directly to the manufacturer's size chart eliminates translation errors.
Frequently Asked Questions
Helpful fit allowances, measuring wisdom, and sizing advice for parents.
How does European (EU) kids shoe sizing work?
European shoe sizing is based on the 'Paris Point' metric unit, where each size increment equals two-thirds of a centimeter (6.67 millimeters). Unlike US sizing, European sizes are continuous and do not reset between toddler and youth categories.
What is a US toddler size 7 in European (EU) sizing?
A US toddler size 7C corresponds to European size EU 23 (accommodating a foot length of approximately 13.4 cm / 5.3 inches).
Why do some US to EU shoe charts have slight differences?
Because US sizing is based on barleycorn units (1/3 inch) while EU sizing is based on Paris Points (2/3 cm), exact mathematical equivalence does not align on whole numbers. Different brands (e.g. Nike vs Adidas vs Geox) may round slightly differently.
What is a youth size 1Y in EU sizing?
A US Youth size 1Y corresponds to European size EU 32 (accommodating a foot length of roughly 19.1 cm / 7.5 inches).
