The corresponding standard height for a 14-year-old boy is 165.9cm. If the boy’s bone age is also 14 weeks old, his height can grow by about 7cm, and his lifetime height is about 172.7cm. To know how much a boy can still grow, you need to do the bone age of the child, which can truly reflect the remaining growth space of the child. If the child’s skeletal age is 13 years old, the height of the child at 13 years old is 159.5cm, and the actual height of the child is 165.9cm, which is probably due to the child’s genetic height. Therefore, the child’s height is measured by bone age, not by age.
