In short
Where the number just works. At Up to 5lbs, 3-6m, 6-9m, 6-12m, 6T, Hatley 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 4T, Tommy Hilfiger Kids, Kyte Baby, Magnetic Me cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Hatley 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 Hatley’s own published chart; the notes here come from public parent discussion.
Hatley’s fit splits by category, and that split is the whole story. Its signature rainwear — raincoats, splash jackets and rain boots — runs big and generous, so parents buy the labeled size (or one up) expecting to roll sleeves and get roughly one-and-a-half to three years and a hand-me-down out of a coat. Its cotton pajamas run the other way: slim and a touch small, so the same shopper who mentally sizes down for the coat should go by the child’s height on the PJs rather than oversizing. Everyday pieces lean toward the generous end like the rainwear. Quality is widely praised — cozy terry/fleece-lined coats, bold prints that draw compliments, and cotton that washes well without fading — with a minority reporting snap failures, a waterproof layer that flakes after a couple of seasons, or an undersized hood on certain jackets. It is a premium-priced brand most regulars buy on sale.

How Hatley’s socks are sized
Hatley sizes socks by shoe size, not age — buy for the shoe size your child wears now; between two ranges, size down so the sock stays up.

Should you buy Hatley?
Consider it if…
- You want rainwear with built-in room to grow — coats and boots run large, so one buy commonly covers a year and a half to three years and still hands down.
- You want genuinely cozy rain gear — the soft terry/fleece lining is the most-praised feature, and the waterproof shell actually keeps kids dry.
- You want pajamas and prints that last — the 100% cotton PJs are reported to hold shape and color wash after wash, and the animal/woodland prints are a repeat delight.
- You care about value over years — the build quality and generous rainwear sizing stretch the usable life across siblings.
Think twice if…
- You’re buying pajamas and reaching for the next size up — don’t; the PJs run slim, so size by height instead.
- You expect flawless durability — a minority report snaps pulling off, the waterproof coating flaking after about two seasons, or a hood that runs small; check closures and hood before a big trip.
- You’re price-sensitive or buying direct — it’s premium-priced and the brand site’s service reviews are mixed; regulars wait for clearance or buy via Zappos, Nordstrom or Amazon.

Does Hatley run big or small?
It depends on the item. Rainwear (coats, splash jackets, boots) runs big and generous, so order your true size for room to grow. Pajamas run slim and a little small, so go by your child’s height and don’t oversize.
Should I size up in the raincoat?
Usually no. Most parents find the labeled size already roomy and just roll the sleeves for the first season; going two sizes up tends to turn it into a trench coat.
Are the rain boots true to size?
No — they run large, often about a half to a full size big. Size down if your child is between sizes or you need them to fit now, and check Hatley’s published insole length against the foot.
Is the quality worth the price?
For most, yes on construction and longevity — cozy lined coats and cotton PJs that don’t fade — but it’s priced high and a minority hit durability or waterproofing issues, so buying on sale is the common advice.
What measurements do I need to size Hatley accurately?
Hatley publishes height, weight, chest, waist, hip in its size chart. Height is the primary driver, and the chest/waist figures let you confirm body fit for a child between sizes.
How do Hatley’s shoe and sock sizes work?
Hatley’s shoes run big, so size down about a half, and they’re a standard, medium width. Kids’ shoe sizes go by foot length, not age — measure your child’s foot and match it to the size. Hatley’s socks are sized by shoe size, not age — buy for your child’s current shoe size, and if they fall between two ranges choose the smaller so the sock stays up. See how every kids’ shoe brand runs and how wide each is cut on our kids’ shoe sizing guide.
