Most boys stop growing after puberty, between the ages of 18 and 20, but there are individual differences.
Boys’ height grows fastest in early puberty, between the ages of 13 and 15, and slows or stops in late puberty. At around 18 years old, because the epiphyses tend to close, the development of the long bones has basically been finalized, so even if he grows taller, the magnitude of his growth will be limited.
Due to some boys due to genetic, environmental, nutritional, sports and other aspects of the impact, may lead to premature epiphyseal closure, so that the boy’s height early stop growing, but most boys will be around 18 ~ 20 years old to stop growing taller.
If a boy’s height growth is too slow or stops growing too early, it is recommended to consult a doctor in time to improve the examination and actively treat if necessary.
