Confused about which size to pick? Learn how to measure your child's chest for the perfect personalized T-shirt.
How to measure for a perfect fit
If you are unsure about the size, the most reliable way to confirm is by measuring a T-shirt that currently fits your child well. Lay it flat, measure the chest from one armpit to the other, and compare it with the size chart.
Choose comfort over exact age
Age is a useful starting point, but children grow differently. If your child is between sizes or you prefer a looser fit, choose one size up.
