Here’s how Cat & Jack 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 Cat & Jack 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 Cat & Jack 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 Cat & Jack’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, 3T, 6X, Cat & Jack 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 5, Il Gufo, Converse Kids, Levi's Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Cat & Jack number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Cat & Jack-specific things the size number alone won’t tell you — drawn from its own charts.
Cat & Jack publishes separate boys’ and girls’ charts (plus toddler versions), so match your child to the right line rather than a single unisex number.
Girls get Slim (5–14) and Plus (7–18); boys get Slim (5–14) and Husky (8–18), with Adaptive offered across the line. Each is the same height as the standard size, adjusted through the waist and seat — a wide net for a non-average build.
Parents land consistently on true-to-size — buy the usual number — while noting it’s cut trimmer than the roomier basics brands, with the leggings the slimmest piece.
You’ll only find Cat & Jack at Target, not on Amazon or resale marketplaces. Target’s 1-year guarantee takes back pieces that wear out for a refund or exchange.
Which trimmer, roomier, or adaptive cuts Cat & Jack publishes alongside its standard sizes.
This is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Cat & Jack’s own published chart; the notes here come from public parent discussion.
Cat & Jack runs true to size for an average build, with a slim, narrow cut. Parents land consistently on true-to-size — buy your child’s usual number — while noting it’s cut trimmer than the roomier basics brands, with the leggings the slimmest. A few find a piece runs a touch large out of the package but shrinks back to true after a wash, so the size you buy is the size you keep.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.

Find my child’s size →Shop Cat & Jack ↗Unusually for a mass brand, Target publishes the full set — height, weight, chest, waist and hip for every Cat & Jack size. Height is the primary driver, but for a child between sizes the chest and waist figures let you confirm body fit instead of guessing.
Yes to all four — a real strength for a budget brand. Girls get Slim (5–14) and Plus (7–18); boys get Slim (5–14) and Husky (8–18); and there’s a full Cat & Jack Adaptive line — sensory-friendly, tagless, with easy closures and wheelchair-friendly cuts.
Through baby and toddler (newborn–5T) they share one chart, so it’s effectively unisex. From size 4 up they split, and boys’ run a bit taller and roomier at the same number — so a girls’ 10 and a boys’ 10 aren’t identical.
It’s Target’s everyday-basics brand, and it carries a 1-year guarantee: if an item wears out or doesn’t hold up within a year, Target takes it back for a refund or exchange with your receipt or Target Circle history.
It’s a Target exclusive — Target stores and target.com only. It isn’t sold through third-party marketplaces.
Each of these is the same numbered size as the regular cut — same length, adjusted through the waist and seat (Slim trimmer, Plus and Husky roomier). So size to your child’s usual Cat & Jack number from the chart above, then pick the cut by build: a smaller waist for Slim, a fuller waist and seat for the roomier cuts. You don’t need a separate measurement to choose. Cat & Jack also carries an Adaptive line, which is about easy closures and sensory-friendly construction rather than a different cut.
Cat & Jack 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.
