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.
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.
Most girls stop growing taller by age 14 or 15. In contrast, after their early teenage growth spurt, boys continue gaining height at a gradual pace until around 18. Note that some kids will stop growing earlier and others may keep growing a few years more.
However, once the growth plates in the bones close, a person will generally not grow any taller. Most females reach their full adult height aged 14–16 years. Most males reach their full height by the age of 16–18 years. It is very unusual for a person to grow after the age of 18 years.
Teens might have slower growth if they: don't get enough protein, calories, and other nutrients in their diet. have a long-lasting (chronic) medical condition, such as problems with the kidneys, heart, lungs, and intestines. have sickle cell anemia.
As mentioned in one of the articles one good way to see if you still have growth potential is to X-ray a wrist- the test is called a Pediatric Bone Age. It will show if your growth plates are still open. A doctor can also request lab tests- checking for hormones- such as thyroid, growth hormone and sex hormones.
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.
Key takeaways: The term “late bloomer” refers to a child who goes through puberty later than their peers. Constitutional growth delay, the medical term for this condition, runs in families. Late bloomers will catch up on their growth and have standard adult height, although it may take a little extra time and patience.

And while it's difficult to say just how much your child will grow during this time, you can count on most of it happening, for girls, between 10 and 14 years, and, for boys, between 12 and 16 years.
In males, there are typically two major growth spurts that occur during childhood and adolescence: Childhood Growth Spurt: This growth spurt occurs between the ages of two to three years and ten to twelve years. During this time, boys typically grow at a steady rate of about two to three inches per year.

"There are actually several published studies showing that, in children, drinking milk is associated with very small increases in height," says Jones. It is important to recognize, however, that these studies are showing a correlation and not a cause and effect relationship.
Overall, our line graph showed that taller people do not necessarily have the biggest hand span as we discovered many children's hand spans were equal in length - despite being different heights!
If you want some guess from me, I am thinking at most 3–4 inches (males grow more than females). 2–3 inches is the average height gain from 15 to 18.
