Bone age closure is at 16 years old for girls and 17-18 years old for boys. Although the closing time is late, it does not mean that the growth will be large. There are several stages in a child’s growth process, with birth length, also known as height, at birth. Childhood growth is also very rapid until the age of 3, when the child grows taller. The faster the growth rate at each stage also means that the child can grow taller. From the age of 3 until the child’s pre-puberty is the plateau period, which is a more balanced growth rate and the main stage in which the child gains height. Early adolescence is when elevation can skyrocket, when children show up as eating more and growing taller. Because this is when bone age changes will have a very large impact on height. When the bone age is about to close, or before the bone age closes, that is, before the boy is 18 years old and the girl is 16 years old, you should continue to strengthen your efforts to grow taller.
