A size “120” isn’t a shoe size or a waist measurement. It’s simply the height in centimetres that the garment is designed for. You measure your child’s height, find the matching label, and that’s it — no cross-referencing age and weight and hoping for the best.

What the Labels Actually Mean
The number on the label is the height in centimetres the garment is designed for. Size 120 fits a child around 120 cm tall — that’s typically a 6 or 7-year-old, which is why Hanna Andersson lists it as “US 6–7.”
This is identical to how H&M, Zara, and most European brands label their clothes. If your child wears a size 128 at H&M, they’ll wear a size 130 at Hanna Andersson. The systems are directly comparable.
A note on size 65 and 70
Sizes 65 and 70 share the same height (66–71 cm) and weight ranges on Hanna Andersson’s official chart. In practice the 70 tends to be cut slightly longer through the body to accommodate a growing infant. If your baby is comfortably in 65, the 70 is the natural next step rather than jumping to 75.
How to Measure Your Child
Hanna Andersson’s system only requires one measurement: height. Stand your child against a wall without shoes, feet flat on the floor, and measure from the floor to the top of their head. Match that number to the chart above.
For baby sizes specifically, weight can help confirm the fit — a particularly chunky or lean baby at the boundary between sizes can use weight as a tiebreaker.
What Hanna Andersson Doesn’t Publish
Unlike brands such as H&M, Next and Old Navy — which publish chest, waist and hip measurements alongside their size charts — Hanna Andersson provides height and weight only. There are no body-measurement data points for any size in their range.
This matters because children of the same height can have meaningfully different chest and waist proportions. A slim 110 cm child and a broader 110 cm child might fit very differently in the same garment. Without chest and waist data there’s no way to verify in advance whether the cut will work for your child’s specific build — you’re relying on height alone.

Does Hanna Andersson Run True to Size?
Hanna Andersson says their clothes are designed to run true to size based on height, and there’s no systematic evidence to suggest otherwise. The brand designs for room to grow — their garments tend to be generously proportioned through the body rather than fitted, which is part of why the same piece can last through multiple growth stages.
If your child is between sizes, the brand’s own guidance is not to size up. Use their height measurement as the primary guide and trust the chart.
Hanna Andersson vs Other Brands
Because Hanna Andersson uses standard European height-based sizing, their labels map directly to most European brands:
| Hanna Andersson | H&M | Zara | Next (UK) |
|---|---|---|---|
| 80 | 80 | 80 | 18–24M |
| 90 | 92 | 92 | 2–3Y |
| 100 | 98–104 | 98–104 | 3–4Y |
| 110 | 110 | 110 | 5–6Y |
| 120 | 122 | 116–122 | 6–7Y |
| 130 | 128–134 | 128–134 | 7–8Y |
The slight mismatches at larger sizes (particularly around 120–130) are because brands don’t all use identical height bracket boundaries even when they both use European sizing. Always verify with your child’s current height rather than matching labels between brands.

Frequently Asked Questions
How does Hanna Andersson sizing work?
Hanna Andersson sizes by height in centimetres, not age. The number on the label (50, 80, 120…) is the height in cm the garment is designed for. Measure your child's height and match it to the chart.
What does Hanna Andersson size 120 mean?
Hanna Andersson size 120 is designed for a child around 120 cm tall — typically a 6 or 7-year-old, which is why the brand lists it as "US 6–7".
Does Hanna Andersson run true to size?
Yes. Hanna Andersson designs to its published height chart with room to grow built in. If your child is between sizes the brand recommends matching their actual height rather than sizing up.
How does Hanna Andersson compare to H&M and Zara?
Hanna Andersson uses the same height-based European sizing as H&M and Zara, so labels map directly. A child who wears H&M 128 will wear Hanna Andersson 130. Slight 2–6 cm mismatches happen because brands draw the bracket boundaries differently.
Does Hanna Andersson publish chest and waist measurements?
No. Hanna Andersson publishes only height and weight for each size — no chest, waist or hip data. For slim or broader-build children there is no way to verify fit in advance from the official chart.
