growing taller Watch
For males - add together your parents' heights (in cm), then add another 13 cm and divide by two.
For females, subtract (rather than add) the 13 cm, before division.
Eg. Your father is 180 cm tall, and your mother 155 cm. If you're male, then your likely full adult/final height will be (180+155+13)/2 = 174 cm.
