We have a few different hat options on the website. Our BonnyBoo and BooBeanie hats are sized by age because they have some stretch in them, these are also machine washable and you’ll find measurements under each size to double check your sizing before you buy.

Our wool hats are sized based on the circumference of your child’s head – there is a guide below but please do measure because we cannot accept returns on hats. To measure place your measuring tape across the middle of the forehead just above the eyebrows, above the ears and round to the back of the head where there is a ridge where the neck meets the skull. Here’s a video to help you.
