Head circumference 52 cm
Tsuno height 5 cm
S | about 48 cm (until about 1 year old)
M | about 52 cm (until about 6 years old)
LL | about 57 cm (for adults)
* If the head above the age of 6 is small, even M will enter without problem but if it is a big head child I think that it will be just better to purchase LL for adults.
