Polarn O. Pyret size guide
The size is your child's height in cm
Polarn O. Pyret sizes by height, nothing else. Measure the child against a wall and round up: a 106 cm child wears 110. The age column is there for gift shoppers.
Save the head column: it is the hat size, and hats are what run out first in November.

Two quick answers
How do Polarn O. Pyret sizes work?
The size is the child's height in cm. Measure and round up: 106 cm means size 110.
Do Polarn O. Pyret sizes run big or small?
Neither: they track height honestly. Use the chest and waist columns if your child is far from average build.
