best way to predict a child's adult height

There's no proven way to predict a child's adult height. However, various formulas can provide a reasonable guess for child growth. Here's a popular example:

*Add the mother's height and the father's height in either inches or centimeters.
*Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls.
*Divide by two.
Most children will reach an adult height within 4 inches (10 centimeters) of this estimation.

Another less accurate way to estimate a child's adult height is to double his or her height at age 2.

Remember, a child's height is controlled by genetics. It's also important to note that children grow at different rates. Some children begin their growth phases early, while others are late bloomers. If you're concerned that your child isn't growing normally, consult his or her doctor. Sometimes an underlying condition affects child growth.
