Here’s how Gymboree fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Enter your child’s measurements once — we’ll size them in Gymboree and at 100+ other brands, each from that brand’s own published chart. Height and weight are required; add chest, waist, hips and inseam to sharpen the fit.
Pick the size your child wears at Gymboree to see which brands have the same label and measurements (twins) and which run shorter or longer (strangers) — based on each brand’s own chart.

Sizes shown use Gymboree’s girls’/unisex chart where the brand splits by gender; boys’ sizes at the same number can run slightly taller.
Where the number just works. At 3-6M, 6-9M, 9-12M, Gymboree lines up with every brand we track — the size carries straight over.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 4T, Polo Ralph Lauren 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.

Gymboree-specific things the size number alone won’t tell you — drawn from its own charts.
Gymboree is generous, especially in tops and around the neck, so a child often stays in a size longer than the label suggests. Pants fit closer to true, and fit can vary by piece.
The Children’s Place owns Gymboree, so the two use close US sizing — a size that fits in one is a safe starting point in the other.
Which trimmer, roomier, or adaptive cuts Gymboree publishes alongside its standard sizes.
This is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Gymboree’s own published chart; the notes here come from public parent discussion.
Gymboree runs big. Most parents find it generous, especially in tops and around the neck, so many size down, and a child often stays in a size longer than the label suggests. Pants fit closer to true, and fit can vary by piece, so it’s worth checking a specific item.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.

Leave the bottoms at their straight size, since sizing the whole set down can leave the pants short. When you’re unsure, match the specific piece’s measurements to your child rather than trusting the set as a block.
Bright, themed, coordinated collections designed to mix and match — playful prints and sets rather than plain staples.
They’re sister brands under the same owner, with similar standard US sizing. Gymboree skews more colorful and boutique-y; The Children’s Place is plainer and cheaper.
On its own site and on Amazon, so you can pick the marketplace you prefer.
It publishes height, weight, and waist. Height is the primary driver; the waist figure helps on bottoms. Given the runs-big reputation, sizing by measurement beats sizing by age.
From the bigger sizes up, Gymboree publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use Gymboree’s girls’/unisex chart.
Gymboree carries kids’ shoes alongside its clothing. Kids’ shoe sizes go by foot length rather than age, and the same size number isn’t cut the same from brand to brand — so measure your child’s foot and check it against the chart. Gymboree’s socks are sized by shoe size, not age — buy for your child’s current shoe size, and if they fall between two ranges choose the smaller so the sock stays up. See how every kids’ shoe brand runs and how wide each is cut on our kids’ shoe sizing guide.
