This calculator is for ethnic Chinese children. This application is for newborns, babies, toddlers and preschoolers with an age of 0 (birth) to 6 years.
This calculator determines head circumference percentile based on age. The percentile describes how a child's head circumference compares to other children. The percentile reports the percentage of children that have a head circumference less than the measured child. For example out of a total group of 100 children, a percentile value of 40 percent means the child measures more than 40 children and measures less than the other 60 children.
A percentile of 50% represents the average head circumference. A percentile value below 50 percent means a child's head circumference is smaller than average. A percentile value greater than 50 percent means a child's head circumference is larger than average. A doctor should be consulted to determine growth status.
