Children’s future height can be predicted using different formulas for boys and girls as follows: 1. Boys: The formula that can be used for boys’ height is (father’s height + mother’s height + 13)/2, which means that if the child’s parents are both around 160cm tall, the child’s height is (160 + 160 + 13)/2, which is the height assessment for boys; 2. Girls: The formula for height can be (father’s height + mother’s height – 13)/2. Children’s height is traceable and can be predicted simply by using the above formula, and children’s final height is also related to factors such as diet later in life.
