Height prediction may not be accurate, but these scientific methods can give you a fair idea of your child's future height:
1. Mid-parent rule: Designed in 1948 by Horace Gray, the mid-parent child height predictor is based on parent’s average height. (3).
Add the mother's and the father's height in inches or centimeters.
Add 5 inches or 13 centimeters for boys; for girls subtract 5 inches or 13 centimeters.
Divide the sum by two.
This method is usually used for children below the age of four. The margin of error in Mid-Parent Rule is plus or minus 4 inches.
3. Bone-age method: This method was derived in 1959 and is considered to be more accurate than the other two methods (6). It involves x-raying the kid's left hand, fingers, and wrist. The bone age is compared to the chronological age. You cannot try this method at home but see a doctor.
