Boys generally stop growing between the ages of 16 and 18, but this varies from person to person. When a boy stops growing depends on when his epiphyses close, and the epiphyses of the femur and tibia are the ones that most affect his height. Generally, height grows fastest during puberty, and during the period of 10 to 15 years old is the period of rapid height growth. At the age of 14 to 15 years old, height growth begins to slow down, and at the age of 16 to 18 years old the epiphyses of the femur and tibia close, and the bones begin to stop growing, and the boy’s height reaches its maximum, so boys generally stop growing at the age of 16 to 18 years old. Although boys generally 16 to 18 years old to stop growing taller, but it varies from person to person, each person’s specific situation is different, usually appropriate physical exercise in daily life, eat more food rich in protein and calcium, to ensure adequate sleep, etc., can make the height in a certain range to promote height growth. When a boy stops growing taller, you need to go to the hospital and ask the doctor to measure whether his epiphysis is closed, and then make a specific judgment based on the examination.
