This app uses WHO tables and data for head circumference for age calculations. The calculator is valid for babies, infants, toddlers and preschoolers with an age range of birth to five years.
This calculator provides your child's head circumference percentile based on age. The percentile shows how your childs's head circumference compares to other children. The percentile tells you what percentage of children weigh less than your child. For example out of a sample of 100 children, a percentile value of 40 percent means your child weighs more than 40 children and weighs less than the other 60 children.
A percentile of 50% represents the average or mean head circumference. A value below 50 percent means a child's head circumference is less than the average. A value greater than 50 percent means a childs's head circumference is above average. A doctor or physician should be consulted to determine growth status.
