Please use a cloth tape to take your measurement. It is better to have a helper do the measuring in order to get accurate measurement. The circumference of the head should be measured at a point approximately one inch above the eyebrows, or at whatever point gives the largest possible measurement. If you find that your measurement falls between two sizes, choose the smaller size for this helmet.

Comment: Bought this at Christmas for my two year old knowing this was going to be the best bet to keep the dirt out of her face. She loves it she still gets to see everything we see, the dirt is out of her face and she can wear her sunglasses underneath with no problems. It has been a great helmet.
