The website Infant Head Circumference Chart offers an online calculator that shows how your child's head circumference compares to other babies. If your child's head size receives a percentile value of 60, this indicates that your baby's head circumference is greater than 60 out of 100 babies. Keep in mind that the use of this calculator is for curiosity only, however.
