Some children, especially girls, often wear kids' hat sizes into their teenage years. Children with larger heads, often boys, may need adult sizes (59+) as early as age 10.

Hats for Newborns

Newborns typically have a head circumference of approximately Ø 35 cm at birth. Hats for newborns usually range between sizes 33 and 39. It’s best to wait until after birth to purchase a hat to ensure the correct size. If buying beforehand, we recommend choosing at least size 37.

How to measure correctly

Use a soft measuring tape and place it around your child’s forehead, just above the eyebrows and ears, measuring the widest part of the head. The measured head circumference in centimeters corresponds to the hat size. For example, if your baby’s head circumference is 45 cm, a size 45 hat will fit.

ATTENTION: Sizes and measurements may vary depending on the manufacturer and hat style.
