An adolescent may expect to grow several inches in several months followed by a period of very slow growth, then will typically have another growth spurt.
“Everybody has a growth spurt, when the growth rate more than doubles over a year or two,” Dr. Alan Rogol, a University of Virginia pediatrician who studies growth at puberty, told Fatherly. “It's always the same.
Some boys will reach their full adult before age 17, while others may continue growing until age 20 or 21. They'll grow around 3 inches per year during puberty, which typically occurs between ages 9 and 14 for boys.
Late bloomers will catch up on their growth and have standard adult height, although it may take a little extra time and patience.
According to World Health Organization (WHO), a 17-year-old boy's typical height is roughly 5′ 7″ (175.7 cm) [1].
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.
Changes in your child's height and weight caused by increases in bone, muscle and fat are the most immediate signs that your child is experiencing a growth spurt. Other signs of a growth spurt include: Decrease or increase in appetite. Fussiness or emotional outbursts.
An X-ray can tell you whether your child is done growing or whether they will sprout up a few more inches over time. If your child is still growing, the long bones in their body will have growth plates on their ends. Growth plates are made up of cartilage that has the potential to become new bone growth.
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.
Height increase averages out to be about 6 centimeters (2.4 inches) per year throughout childhood. Then there is a period of slow growth right before puberty. Once puberty starts, there is a sharp increase in growth of about 8 centimeters/year.

Second puberty isn't an official medical term. It's more like slang for significant hormonal and bodily changes women experience after “first” puberty and leading up to menopause.
Dweck says there's no such thing as a second puberty—we're only going to suffer through that once, thank god. But your body is going to naturally change as you get older, and a number of things can mess with your hormones in your 20s and 30s, which might cause puberty-esque symptoms.
There's no proven way to predict a child's adult height.
Most will have reached their adult height by the time they are 14 or 15 years old. This major growth spurt happens during the phase of physical and psychosocial development known as puberty. Everyone starts puberty at a different time, and genetics largely determines growth patterns.
Taking care of himself — eating well, exercising regularly, and getting plenty of rest — is the best way for your son to help his body reach its natural potential. No pill, formula, or nutritional supplement can increase someone's height. Mostly, our genes determine how tall we will be.
Kids tend to get taller at a pretty steady pace, growing about 2.5 inches (6 to 7 centimeters) each year. When it comes to weight, kids gain about 4–7 lbs. (2–3 kg) per year until puberty starts. This is also a time when kids start to have feelings about how they look and how they're growing.
In both sexes, height growth continues until the growth plates close toward the end of puberty. Growth plates usually close at 15–16 years old in girls and at 17–18 years old in boys. However, this period can rarely continue until a person is 19–20 years old.
A major growth spurt happens at the time of puberty, usually between 8 to 13 years of age in girls and 10 to 15 years in boys. Puberty lasts about 2 to 5 years.
