Size Guide
Find the right fit with our standard size chart — then use Size Finder for a personalised recommendation.
How to use this chart
Our sizes follow standard US kids' sizing. Match your child's measurements to the row that fits best. If they're between sizes, we usually recommend sizing up for room to grow — especially for active little ones.

How to measure
For the most accurate fit, measure your child without bulky clothes on:
- Height — stand them against a wall, mark the top of their head, and measure from floor to mark.
- Weight — use a home scale, or note their weight from a recent check-up.
- Chest — wrap a soft tape measure around the fullest part of the chest, under the arms.
Compare your numbers to the chart above. When in doubt, Size Finder can recommend a size based on age, height, or weight.
Between sizes?
If your child is tall for their age or between two rows, the larger size often works better — kids grow fast and a little extra room keeps outfits comfortable longer.
