In general, boys can grow up to about 25 years old, but it varies from person to person. To see if you can grow taller, it depends on whether the epiphysis is closed or not. If the epiphysis is already closed, it’s basically set. If it is not closed, there is still room for growth. To find out whether the epiphysis is closed or not, you can diagnose it by taking X-rays. Before the epiphyseal line is closed, it is recommended to take more calcium, strengthen nutrition and exercise, and there is still hope for growth. Of course, this is also largely determined by genetics.
