What are plus kids' sizes?Same length, roomier waist and hips — brand by brand

Plus sizes are for kids who fit a regular size in height but need more room through the waist and hips. They keep the same length as the standard size and add room in the waist and hips. Here's which of the brands on Little & Youth make plus sizes — and how differently each one defines “plus.”

The short answer: A plus size keeps the exact same height as the regular size and adds room through the waist and hips. But “plus” isn’t a set amount: it adds just a few inches in the smaller sizes, then more and more as the sizes go up — reaching 5½ inches in the waist at the top of the range, where the brands vary the most. So if the length already fits but the waist and hips run tight, a plus is the fix — just don’t count on every brand’s “plus” meaning the same thing.

How much does a plus actually add?

Same height as the regular size — only the waist and hips change. By how much depends on the brand, and on the size.

“Plus” isn’t one fixed amount

Every published plus size — one dot per brand, per size — by how much it adds at the waist. The amounts spread out at every size, and the range climbs as the sizes go up — past 5 inches — so the label alone won't tell you the fit.

Common questions about plus kids' sizes

What is a plus fit in kids' clothes?

A plus size keeps the same length as the regular size but adds room through the waist and hips. It's made for a curvier child who fits a size in height but finds the regular waist and hips too tight. Across the brands that publish figures the added waist room averages about 3–4½ inches — though, as the chart above shows, it isn't standardized from brand to brand.

Is a plus size longer than a regular size?

No — same height; only the waist and hips are roomier. So if the length is right but the waist and hips are tight, a plus usually fixes it without adding length.

How much roomier is a plus waist?

It depends on the brand and the size — that's the point. For the smaller sizes it adds just a few inches, but it grows in the bigger sizes, reaching 5½ inches at the top of the range. Target Cat & Jack adds the most, while Gap Kids and Old Navy add the same amount at every size.

Does a plus add room in the hips too?

Yes — that's part of what defines a plus fit. Across the brands that publish a hip figure it adds about ½–4 inches through the hips, on top of the waist room. Check the hips column above for each brand.

My child's waist fits, but I need the length longer or shorter — what then?

When the waist already fits, changing the size just to fix the length usually leaves the waist wrong again. The better move depends on which way you need to go:

Waist fits, needs more length: don't just size up — a bigger size adds even more room in the waist along with the length, so it goes loose. Pick a plus in the longer size instead: it gives the length while keeping the roomier waist that already fits. If the brand has no plus size, look for an adjustable elastic waistband (inner button tabs), which many kids' pants have.

Waist fits, needs less length: don't size down — a smaller size cuts the waist room with it, so it'll be too tight. Keep the size that fits the waist and have the length hemmed, or choose a style with an adjustable or roll-up hem. A plus won't help here, since plus changes the waist, not the length.

Either way, Little & Youth does the matching for you: enter your child's waist and height and it shows, brand by brand, the size and fit — regular or plus — that best lines up with both measurements at once, and points you to the brands with plus or adjustable-waist options. So instead of guessing which measurement to compromise on, you start from the choices that already come closest on both.

Which brands make plus sizes?

On Little & Youth, Target Cat & Jack, JCPenney Thereabouts, Lands' End Kids, French Toast, Under Armour Kids, Gap Kids, Children's Place, and Old Navy all carry plus sizing. Coverage varies by brand — some carry plus only in the bigger sizes, and a couple carry plus sizes without publishing a comparable chart — so check the size range above.

How we know this is accurate. Every figure behind this page is transcribed from that brand's own published US size chart — the plus measurement compared against the same brand's regular size at the same label. No estimates; where a brand carries plus sizes without a comparable chart we mark it not published rather than guess. Brands update their charts, so always confirm against the brand's live chart before you buy. Little & Youth is independent and not affiliated with any brand listed. Figures verified 2026-08-24.
