babyGap
Here’s how babyGap fits your child compared to other brands you might be considering, so you know before it’s in your cart.
What size is (and isn’t) like babyGap at other brands?
Find your child’s babyGap 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.

In short
Where the number just works. At Up to 7 lb, babyGap 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 2T, Macy's Epic Threads, Macy's First Impressions, Walmart Wonder Nation cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a babyGap 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 babyGap’s own published chart; the notes here come from public parent discussion.
babyGap runs true to size on length and roomy through the body. Gap is widely described as cut generously, and the toddler sizes run a touch big — a younger or leaner toddler can size down a range. The trait parents mention most is consistency: once you know your child’s Gap size, it tends to hold from piece to piece. A few report specific items (like necklines) fitting snug.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
Should you buy babyGap?
Consider it if…
- You want a step up from the value tier — 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 a brand that carries as they grow — it runs from newborn through big-kid without switching labels.
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 like data to size by — Gap publishes height and weight only, with no chest or waist to fine-tune a between-sizes fit.
- You’re placing a big order — sizing gets revised over time, so confirm on Gap’s live chart first.

Should I size down in babyGap?
For a lean or petite baby, often yes on the toddler sizes, which run a touch big — a younger or slimmer toddler can drop a range. For an average or chunkier baby, buy the straight size; Gap’s roomy body cut leaves growing room without swimming. Since Gap publishes height and weight but no chest, lean on your child’s real measurements over the age label whenever you’re between sizes.
Is babyGap the same as GapKids and Gap Factory?
Same brand, different slices: babyGap covers newborn to about 5T, GapKids picks up the bigger sizes, and Gap Factory is the outlet line — the same look at a lower price. Fit stays consistent across them.
Where can I buy babyGap?
On gap.com and Amazon, plus Gap and Gap Factory stores. Gap Factory carries similar styles at a lower price.
babyGap vs. Old Navy — which should I buy?
Same parent company, different ends. babyGap is a bit nicer and runs roomier, while Old Navy is cheaper and runs small — so a size that fits in Gap often needs to go up at Old Navy.
What measurements do I need to size babyGap?
Gap publishes height and weight. Height is the primary driver; because it doesn’t publish chest or waist, lean on your child’s actual measurements over the age label.
