Youth shoe size chart
Age is only a rough guide. Foot length is the better starting point for infants, toddlers, little kids, and youth sizes.
| Foot length | US kids | UK kids | EU | Approx age | Stage |
|---|---|---|---|---|---|
| 20.5 cm / 8.07 in | US 1Y | UK 13 | EU 32 | 7-8 years | Youth |
| 21.5 cm / 8.46 in | US 2Y | UK 1 | EU 33-34 | 8-9 years | Youth |
| 22.5 cm / 8.86 in | US 4Y | UK 3 | EU 35-36 | 9-11 years | Youth / adult crossover |
| 23.5 cm / 9.25 in | US 5Y | UK 4 | EU 37 | 10-12 years | Youth / adult crossover |
| 24.5 cm / 9.65 in | US 6Y | UK 5 | EU 38 | 11-13 years | Youth / adult crossover |
| 25.0 cm / 9.84 in | US 7Y | UK 6 | EU 39-40 | 12+ years | Youth / adult crossover |
Kids shoe sizes repeat numbers across infant, child, and youth ranges. Keep C/Y labels visible to avoid choosing the wrong range.

FAQ
Can adults wear youth shoe sizes?
Sometimes. Some youth sizes overlap with smaller adult sizes, especially women's sizes, but width and style may differ.
What does 6Y mean?
6Y is a youth shoe size, not an adult size 6. Compare it by foot length and brand chart.
Are youth sizes the same as men's sizes?
Some big-kid youth labels can be close to small men's labels by length, but fit and width may differ.
