Yes, your son can still grow after 16, though the most significant growth spurt usually slows down, with most boys adding another inch or two by 18, as growth plates in bones harden after puberty, typically ending around 16-18, but genetics, nutrition, and sleep play big roles in final height.
Lack of height change over time: If you haven't noticed an increase in height for over 1-2 years, it's likely that you've stopped growing. Maturity in physical appearance: Your body will look more adult-like, with features such as facial hair in males or fully developed hips and breasts in females.
Add the mother's height to the father's height in either inches or centimeters. Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls. Divide by 2.
After the growth spurt during puberty, which differs slightly for girls and boys, neither will typically grow much more, and girls typically stop growing by 15, while boys stop at around 18 years of age. That being said, there are environmental factors that can affect the height of a child.
Both early and late puberty typically result in the same average height (measured in inches). However, boys who experience late puberty often grow at a faster rate to compensate for the time they did not grow earlier. During puberty, boys usually reach 92% of their adult height.
The classic presentation of delayed puberty includes diminished height compared with peers (due to lack of pubertal growth acceleration) and lack of development of secondary sex characteristics; that is, no testicular enlargement (<4 mL) in boys by age 13.5 to 14 years or lack of breast development (Tanner I breasts) ...
Testosterone is responsible for the development of secondary sex characteristics, features of male development (including characteristics that are not part of the reproductive system, such as facial hair growth and voice change). Sexual development occurs in a set sequence: Enlargement of the scrotum, and testes.
Taking good care of yourself — eating well, exercising regularly, and getting plenty of rest — is the best way to stay healthy and help your body reach its natural potential. There's no magic pill for increasing height. In fact, your genes are the major determinant of how tall you'll be.
Strength training does not stunt growth…. however, maximal lifting (highest weight amount you can lift one to three times) may put you at more risk for injury to the growing areas of a child's body. Therefore, max lifting should be discouraged until after puberty.
How to predict how tall a child will be. According to Johns Hopkins Medicine, people may wish to try the following formula for predicting how tall a child will be: Measure the height of both biological parents. For male children, add 5 inches (in) to the father's height, add the mother's height, then divide by 2.
The best predictor of a child's height is their parents' height or, more specifically, the mid-parental height. The mid-parental height is calculated by adding the mother's and father's height, adding 13 cm (5 inches) for boys or subtracting 13 cm (5 inches) for girls, and then finally dividing by 2.
Helping Your Child Grow
Your child's growth pattern is largely determined by genetics. Pushing kids to eat extra food or get higher amounts of vitamins, minerals, or other nutrients will not increase their height and may lead to weight problems. Accepting kids as they are helps them build self-acceptance.
The nutrients that support height growth include the following:
If the pituitary gland doesn't make enough hormones, normal growth slows down or stops. Kids and teens with GH deficiency grow less than 2 inches (5 centimeters) a year. GH deficiency happens if the pituitary gland or hypothalamus is damaged or doesn't work as it should.
Changes in Boys
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.

How to Reopen Growth Plates Naturally
According to CDC data, the average height for 16-year-old boys is approximately 5 feet 10 inches (178 centimeters). It's important to remember that growth patterns can vary among individuals, and there is a wide range of normal growth.
Scientists estimate that about 80 percent of an individual's height is determined by the DNA sequence variations they have inherited, but which genes these changes are in and what they do to affect height are only partially understood.
A single night of no sleep will not stunt growth. But over the long term, a person's growth may be affected by not getting enough sleep. That's because growth hormone is normally released during sleep. If someone consistently gets too little sleep (known as "sleep deprivation"), growth hormone is suppressed.
Boys have pubertal concerns and worries, too, including:
Next, the doctor performs a physical exam to check for signs of puberty. These may include the growth of pubic and underarm hair. Girls who have begun puberty may have breast buds, which are small, firm lumps beneath the nipple and areola. In boys, increased testicle and penis size may be observed.
