Boys’ bones close around the age of 18, but everyone is different, some will close earlier, some will close later. If you are growing faster, you may close early, and if you are growing slower, you may close a few months or a year later. If you do not grow taller in the near future, you need to take a positive and lateral knee radiograph to see if the epiphysis is closed, and if it is not closed, there is still a chance to grow taller. Get enough sleep, about 8-9 hours, and eat more nutritious food, especially food with more protein to promote growth. If the epiphysis is completely closed, there is no chance of growing taller, and the human body’s growth is also related to genetic factors.
