Here’s how Athleta Girl fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Find your child’s Athleta Girl size on the left. Twins wear the same number the same way — your size carries straight over. Strangers use the same number but cut it shorter or longer, so don’t trust the label alone.

Where labels drift. The exceptions are the “strangers” above — e.g. at size L, Nautica, Amazon Essentials Kids, Reebok Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Athleta Girl number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.
