Genetics is the biggest factor determining the height of a boy. External factors such as diet and sleep duration also play an important role. After puberty, the growth rate of boys' height will be very slow, most of them reach their adult height by the end of adolescence.
1. At what age do boys grow in height?
The age at which boys grow taller at puberty is the fastest. Some boys have early puberty at the age of 9, and some boys have late puberty at the age of 15. For the most part, the boy's height is best developed between the ages of 12 and 15.
Puberty in boys can be lasting from 2 to 5 years. Longer puberty does not mean better height growth than people with less puberty time.
Most boys grow in height only a little after the age of 18. In rare cases, children hit puberty in their teens and continue to grow in height until the age of 20.
The reason most boys stop growing in height after puberty is that the growth plates have fused. Growth cartilage is an elongated bone found near the ends of the long bones of children and adolescents.

2. What factors affect height growth in boys?
Much of height is determined by genetics. However, other factors such as sleep time and nutrition also play an important role in the rate of height growth in men. Specifically:
2.1. Genetics
Height is most influenced by genetic factors. It is estimated that about 80% of height is influenced by genetics, the remaining 20% by external factors.
Predicting adult height in boys is calculated by the formula:
(Father's height + Mother's height) divided by 2 and then added 6cm. Predicting adult height in girls is calculated by the formula:
(Father's height + Mother's height) divided by 2 and then subtracted 6cm from the calculated result. For example, if the father has a height of 1m80 and the mother is 1m62, then the boy's height is predicted to be about 1m78. However, this is only a relative calculation.
2.2. Nutrition
After genetics, nutrition is the second most important factor that has a great influence on a child's height. Malnourished children are often stunted and retarded.
Dietary lack of protein is the most common cause of growth restriction in young children. In addition, deficiency of minerals, vitamin D, vitamin A also affects the growth rate of children.

2.3. Sleep
Sleep is the time for the body to produce growth hormone and thyroid stimulating hormone. These two hormones are essential for bone growth.
Insufficient sleep can lead to stunting. However, at present, more research is still needed to fully understand the role of sleep in the growth of children's height.
2.4. Medicine
Some stimulant drugs used in the treatment of ADHD can cause growth retardation. However, more research is still needed.
In 2015, a study of 410 children between the ages of 0.9 and 16.1 investigated the link between ADHD stimulants and the risk of stunting. The researchers found that the drugs led to a temporary halt in height and weight growth. Even after 6 years of stopping taking the drug, the children were still not catching up to the expected growth rate.
Meanwhile, in 2014, another study of 340 children with ADHD into adulthood concluded that stimulants did not affect children's adult height.
2.5. Health status
Inherited or chronic diseases that can increase the risk of stunting include:
Thyroid disease Turner syndrome Osteochondromal dysplasia Down syndrome Russell-Silver syndrome Bone disease

3. How to grow taller after puberty?
Height is less affected by external factors after the growth cartilage has fused. Even exercise along with a healthy diet did not improve height in this case.
Instead, you should focus on improving your posture. By straightening the spine, the height will increase a little, but not make the bones longer.
Some ways to improve posture include:
Do stretching exercises regularly Do Core exercises Regularly sit with proper posture Exercise regularly Overcome feelings of laziness Height fluctuates approx. 0.76cm from waking up to going to bed due to the pressure on the spine during the day. You will notice yourself a little taller in the morning than in the evening. If you are still growing taller, a balanced diet and enough sleep will help maximize that potential.
