Child growth: Can you predict adult height?

Question

What's the best way to predict a child's adult height?

No name
No state given

Answer

There's no proven way to predict a child's adult height. However, several 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 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 about your child's growth, consult his or her doctor.
