H&M Kids
Here’s how H&M Kids fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Find your child’s size in H&M Kids
Enter your child’s measurements once — we’ll size them in H&M Kids 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.
Your child wears one size in H&M Kids. What should you buy elsewhere?
Pick the size your child wears at H&M Kids 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.
Show the full cross-brand table (every size)
Sizes shown use H&M Kids’ 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 Up to 1 month, Premature, 6X, H&M Kids 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 5T, Tommy Hilfiger Kids, Calvin Klein Kids, Magnetic Me cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a H&M Kids number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Fit & the transitions that trip parents up
H&M Kids-specific things the size number alone won’t tell you — drawn from its own charts.
Sized the European way — by height in centimeters
H&M keys its kids’ sizing to height in centimeters rather than a US age number, so measure your child’s height first. The figures on this page are converted from H&M’s published cm bands to inches.
Cut slim and long
“Tall but skinny” — the length runs generous while the waist runs narrow. It fits lean children well; broader kids often size up for the waist. Stiffer poly, cord and denim feel less forgiving than the stretchy cotton pieces.
Toddler sizes run large, then settle
The 2T–4T range can run large overall, with the fit settling closer to true around 5–6.

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 H&M Kids’ own published chart; the notes here come from public parent discussion.
H&M Kids is cut slim and long — “tall but skinny.” It sizes the European way — by height in centimeters — and parents find the length generous while the waist runs narrow, so it fits lean children well and broader kids often size up for the waist. The toddler sizes (2T–4T) can run large overall before the fit settles closer to true around 5–6. Fabric matters, too — stiffer poly, cord and denim feel less forgiving than the stretchier cotton pieces.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
Should you buy H&M Kids?
Consider it if…
- You want low prices for on-trend style — value-tier with a current, Scandinavian-leaning look.
- You want cotton basics — its stretchier cotton pieces are the softer, more forgiving side of the range.
- You like a huge, frequently-refreshed range — lots of styles, updated often.
Think twice if…
- You shop on Amazon — H&M is direct-to-consumer; you’ll buy on hm.com or in H&M stores.
- You want it to last for years — it’s fast-fashion value; the stiffer synthetic pieces show wear or pill sooner than premium brands.
- You want staples that restock — styles turn over fast, so a favorite may not come back.
Skip the cross-referencing — let Little & Youth do it.

Why are H&M kids sizes labelled by height in centimeters?
H&M uses European, height-based sizing (for example 104 cm ≈ age 4), rather than US age labels. Our comparison converts it from real height, and you can switch this page between inches and centimeters with the toggle above the table.
Where can I buy H&M Kids?
On hm.com and in H&M stores. It’s direct-to-consumer.
My child is between H&M sizes — how do I choose?
Go by build: for a lean child the labelled size (or even down) usually works, while a broader child should size up for the narrow waist. Because the length runs long, a tall-and-slim child is exactly who H&M fits best.
What measurements do I need to size H&M Kids?
Height first, then the waist — the waist is where H&M runs narrowest, so it’s the measurement most likely to decide a between-sizes call. Chest helps on tops.
Do H&M Kids boys’ and girls’ sizes fit the same?
From the bigger sizes up, H&M Kids publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use H&M Kids’ girls’/unisex chart.
How do H&M Kids’ shoe sizes work?
H&M Kids 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. See how every kids’ shoe brand runs and how wide each is cut on our kids’ shoe sizing guide.
