Size guide

Size Guide

Sizing varies by brand. Each brand uses its own measurements, and some styles run large or small. For the most accurate fit, check the size chart and sizing notes on each product page before you order.

How to measure

Height: measure from the top of the head to the heels, standing (or lying flat for babies).
Weight: use your child's most recent weight.
If your child is between sizes, we recommend choosing the larger size for room to grow.
