Find your child’s Gap Kids 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.

Sizes shown use Gap Kids’ girls’/unisex chart where the brand splits by gender; boys’ sizes at the same number can run slightly taller.
In short
Where labels drift. The exceptions are the “strangers” above — e.g. at size 16, Lacoste Kids, Appaman, Original Penguin Junior cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Gap Kids number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

What shoppers say about the fit
Community consensus
Shopper opinion · not Little & Youth’s measurementThis is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Gap Kids’ own published chart; the notes here come from public parent discussion.
GapKids runs roomy through the body and true on length, with unusually consistent sizing. Like babyGap, it’s cut generous in width — a lean kid can size down, while an average or chunkier kid gets room to grow — and the length runs about true. Its real strength is consistency: the size holds piece to piece better than most, and noticeably more than sister brand Old Navy. Size by your child’s height and chest rather than the age on the label.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
Should you buy Gap Kids?
Consider it if…
- You want a step up from value basics — Gap’s quality, denim and prints sit a notch above the cheaper brands.
- You want frequent big sales — 40–50% off runs often, and Gap Factory carries the same styles cheaper year-round.
- You want Plus sizes — GapKids carries a Plus range up to 18, unusually inclusive for a mid-tier brand.
Think twice if…
- You’re on a tight budget at full price — it’s mid-tier; wait for a sale or shop Gap Factory.
- You want premium or heirloom pieces — it’s nice mid-tier basics, not a boutique label.
- You want timeless staples only — much of the line follows seasonal trends and logo prints.
Skip the cross-referencing — let Little & Youth do it.

Is GapKids the same as babyGap and Gap Factory?
Same brand, different slices: babyGap covers newborn to about 5T, GapKids picks up the bigger sizes (roughly 4–14, plus a Plus range), and Gap Factory is the outlet line — the same look for less. Fit stays consistent across them.
GapKids vs. Old Navy — which should I buy?
Same parent company, opposite ends. GapKids is a bit nicer, runs roomier and sizes more consistently; Old Navy is cheaper and runs small — so a size that fits in Gap usually needs to go up at Old Navy.
What measurements do I need to size Gap Kids accurately?
Gap Kids publishes height, weight, chest, waist, hip in its size chart. Height is the primary driver, and the chest/waist figures let you confirm body fit for a child between sizes.
Do Gap Kids boys’ and girls’ sizes fit the same?
From the bigger sizes up, Gap Kids publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use Gap Kids’ girls’/unisex chart.
Does Gap Kids offer slim, plus, husky sizes?
Yes — Gap Kids carries slim, plus, husky options in addition to its standard cut.
Where do I buy Gap Kids?
Gap Kids is sold on its own site and on Amazon, so you can pick the marketplace you prefer.
