This application predicts the goal height of the children based on the parent’s height. The height shown is the midparental height for the child. This number plus or minus 4 inches (or plus/minus 10 centimeters) is the range in which you could expect your child to be. Keep in mind that other factors may influence your child’s growth, including his overall health and nutritional status.
