Children's Shoe Size Guide

2 min read · Updated October 27, 2026

Children’s shoe sizes are best chosen from measured feet and the brand’s fitting guide. Age is not a reliable size measurement.

Read the children’s range

US labels can use C for children and Y for youth. Vans’ kids chart moves from 13.5C to 1Y. The numbering rollover is not a drop in foot length. Match the exact brand’s table rather than inferring from age.

Measure both feet

Follow the manufacturer’s standing-foot method, use the intended socks and check both sides. Recheck when shoes feel tight or growth changes the fit; a predicted age-to-size table cannot replace measuring.

Check room without excessive movement

Use the brand’s toe-room and width guidance. Shoes should hold the heel, allow comfortable movement and not press toes together. Excessively long shoes are not automatically good growing-room choices.

Youth shoes are not automatically adult shoes

Overlapping label sizes do not guarantee the same last, materials or cushioning. Compare the current product descriptions and fit before treating a youth size as an equivalent adult purchase.

Frequently asked questions

Does this guidance guarantee fit?
No. Use current product-specific measurements and an actual fit check; generic conversions are approximate.
