PHV females increased by 7.89 cm at 11-12 years, while males increased by 9.9 cm at 13-14 years. Menarche occurred at the age of 12.2 years on average, with the oldest being 14.7 years and the youngest being 9.6 years.
Boys tend to show the first physical changes of puberty between the ages of 10 and 16. They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
Men usually stop growing after puberty — around the age of 18 — but some may experience spurts until their early 20s. There are several factors that impact male growth and determine their final adult height, including genetics, health during childhood, and hormonal imbalances.
Children assigned male at birth will experience a growth spurt between ages 12 and 17. Each child grows at their own pace and may experience puberty changes earlier or later than their peers. Adolescents will increase in height at an average of 3 to 4 inches (9 to 10 centimeters) during their growth spurt.
People cannot control most of the factors that influence their height. This is because DNA determines these factors, and they cannot change. However, there are some factors that can increase or reduce growth during childhood and puberty.
Although some men may continue to grow in their 20s, most men's growth plates are closed by 21 years. Hence, it is unlikely for men to grow after 21 years, with some exceptions. In a healthy growth pattern, your bone increases in length due to the growth plates in the bone called epiphyses.
An adult cannot increase their height after the growth plates close. However, there are plenty of ways a person can improve their posture to look taller. A person can also take preventive measures against height loss as they age.
Most people attain their final adult height at 18. Increasing your height after 18 is not possible, even through nutrition and exercise, because the growth plates stop growing.
Generally, speaking, most boys stop growing between the ages of 16 and 18. Note that some kids will stop growing earlier and others may keep growing a few years more. This variation is normal, but the average boy will stop growing by the end of high school. Essentially, when puberty stops, so does most of their growth.
Some people are “late bloomers” and do not hit their final growth spurt until their late teens or early twenties. After you reach your full adult height, you will not get taller.
The fastest rate of growth is usually 1 to 2 years after puberty has started. Developing physically into an adult takes 2 to 5 years. Most boys will stop growing taller by age 16 and will usually have developed fully by 18.
The truth is, stretching isn't going to make you taller; it can't lengthen your bones. But stretching regularly can make you appear taller by lengthening your muscles and improving your posture.
Although a few people may continue growing even in their early 20s, most adults cannot increase their height after age 21 if their growth plates close. However, there are ways to maximize your height in your growing years through nutrition and exercise. And if you're already over 21, there are ways to appear taller.
The start or end time is different for each child. Normally, puberty in boys lasts 2 to 5 years and will end between the ages of 16 and 18. This process can be shortened if the signs of male puberty come at the same time. The later the signs appear and are far apart in time, the longer a child's puberty will take.

Boys finish their growth and physical development. Many may not develop facial hair until this step in the process. Pubic hair may extend out to their thighs, and some boys may have a line of hair up to their belly button. Most boys finish growing by age 17, but some may continue growing through their early 20s.
At 15 years old, being 5′10″ puts you taller than 96% of boys your age. IF you continue along that trajectory and end up at the 96th percentile for adult men, you would be 6′2.5″.
By far the most common reason is that you started puberty early. Growth in height os over at the end of puberty.
You developed a hormone deficiency (HGH or thyroid) or a serious medical illness (e.g., celiac disease, kidney failure) or were treated with a medication that stunts growth (steroids, chemotherapy).
