Here’s how Gymboree fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Find your child’s Gymboree 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 5, Il Gufo, Magnetic Me, Converse Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Gymboree number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.
