What size is (and isn’t) like Cat & Jack at other brands?
Find your child’s Cat & Jack 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 Cat & Jack’s girls’/unisex chart where the brand splits by gender; boys’ sizes at the same number can run slightly taller.
In short
Where the number just works. At Preemie, 2T, 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, Magnetic Me, Converse 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.

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 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.
Should you buy Cat & Jack?
Consider it if…
- You want one brand from newborn to size 18 — few mass brands span the whole range.
- Your child is between sizes or a non-average build — Slim, Plus, Husky and Adaptive fits are all on the table.
- You want a built-in safety net — Target’s 1-year guarantee takes back Cat & Jack that wears out, for a refund or exchange.
- You want everyday value — Target-basics pricing for durable staples, not a boutique markup.
Think twice if…
- You shop third-party marketplaces — Cat & Jack is Target-exclusive, so it won’t show up on Amazon.
- You want heirloom or premium construction — this is everyday-basics value, not a boutique label.
- You need sizing beyond size 18 or in centimeters — it’s US sizing with a tween ceiling.

What measurements do I need to size Cat & Jack accurately?
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.
Does Cat & Jack have slim, plus, husky, or adaptive sizes?
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.
Do Cat & Jack boys’ and girls’ sizes fit the same?
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.
Does Cat & Jack hold up — and what if it doesn’t?
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.
Where do I buy Cat & Jack — can I get it on third-party marketplaces?
It’s a Target exclusive — Target stores and target.com only. It isn’t sold through third-party marketplaces; the biggest of those is Amazon, and Cat & Jack isn’t there. If a third-party marketplace like Amazon is what you need, Little & Youth can point you to the closest-fitting size at brands that do sell there.
