How to take measurements

Using a flexible measuring tape, measure the circumference of the baby's head around the forehead, over the ears, and around the most prominent part of the back of the head, without pulling tight.
The measurements correspond to the reference head circumferences used for each size. Ages are approximate.

If you are unsure between two sizes, you can contact us and we will help you choose the most suitable one.
