When in Doubt, Size Up

Kids grow fast. If they're between sizes or right at the top of a range, go one size up. It'll fit perfectly within a few months — and they'll get more wear out of it.

Helpful Tips

Measurements are taken flat across the chest, not circumference. Double the chest width for the full chest measurement.
GrandTee shirts are 100% cotton. Expect about 5% shrinkage after the first wash — we recommend cold wash, tumble dry low to preserve the print.
Big kids (ages 10–12) who wear adult smalls may prefer Youth XL for a comparable fit.
Not sure of their exact measurements? Check the tag on a shirt they already wear — most kids' shirts list chest width or size range.
For a relaxed/loose fit, size up one. For a fitted look, use the age range as-is.
