In short
Where the number just works. At 6-9M (65 cm), 6-7 (120 cm), 14-16 (160 cm), Hanna Andersson 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 2T (85 cm), H&M Kids, Burt's Bees Baby, Carter's cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Hanna Andersson 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
Hanna Andersson-specific things the size number alone won’t tell you — drawn from its own charts.
Sized in centimeters by height (120 ≈ 6–7 years)
Hanna uses one unisex ladder keyed to height in centimeters (120 ≈ 6–7 years). Measure your child’s height and follow Hanna’s own guide rather than the age label.
Runs big — don’t size up
Hanna is generously cut, and the shared advice is not to size up — even a child near the top of a range usually shouldn’t bump up. Sizing correctly still leaves room to grow, which is part of why the pieces last.
Pants and leggings run loose at the waist
The bottoms run especially loose through the waist, worth knowing for a slim child.

Should you buy Hanna Andersson?
Consider it if…
- You buy for durability — Hanna’s core cotton is famously long-lived; parents report play dresses and pajamas surviving 100+ washes and multiple kids with little fading.
- You want the best pajamas — sleepwear is the category Hanna does best: signature soft organic cotton, built to last.
- You think in cost-per-wear — premium up front, but everyday pieces get worn hundreds of times, which makes the price pencil out over years or multiple children.
- You want organic cotton staples with a heritage of quality.
Think twice if…
- You’re price-sensitive — Hanna is premium ($$$ tier); it’s best value on core cotton and on sale, not at full price for occasion pieces.
- You’re buying swimwear — reviewers note suits pill and fade sooner than the price suggests; the cotton basics are the strength.
- You want trendy or cheap — Hanna is classic and built to last, not fast-fashion.

How do I pick the right Hanna Andersson size?
Measure your child’s height in centimeters and match it to Hanna’s height guide rather than the age label — because it’s cut generously, even a child near the top of a range usually shouldn’t bump up. Pants and leggings run especially loose at the waist, so mind the waist there. You can switch this page’s figures to centimeters with the toggle above the table to line them up against Hanna’s own chart.
Why are Hanna’s sizes in centimeters and years?
Hanna uses European-style sizing by height in centimeters (for example, 120 ≈ 6–7 years). Our comparison converts it to US sizes from real height, and you can switch this page’s figures to cm with the toggle above the table.
Is Hanna Andersson worth the price?
For core cotton — play dresses and especially pajamas — most long-time buyers say yes, because the durability drives the cost-per-wear down over years and multiple kids. Swimwear is the weaker spot.

Where can I buy Hanna Andersson?
On its own site and on Amazon, plus frequent seasonal sales worth waiting for.
What measurements do I need to size Hanna Andersson accurately?
Hanna Andersson publishes height, weight in its size chart. Height is the primary driver on this chart.
How do Hanna Andersson’s sock sizes work?
