Many teenage boys wonder if they’ll keep getting taller after turning 17. The truth is, there’s no easy answer. Every boy is different, and their growth can change a lot.
For most boys, they stop growing taller before or when they turn 18. Boys and girls grow at different speeds, especially before age 10. The CDC says the average adult male height in the U.S. is 69 inches (5 feet, 9 inches).
By age 16, most boys finish growing. But, some might get a little taller, maybe up to an inch, as they get older. Plus, their muscles keep growing even into adulthood. Boys typically grow more in middle school than girls do. They usually end up taller than girls. Between 12 and 15 years old is when boys often grow the most.

Understanding Male Growth Patterns
When talking about growth among males, a few key points are vital. The average height for adult men in the USA is important to consider. CDC growth charts for boys also give us useful details.
Average Height for Adult Men
The average height for men over 20 in the USA is 69 inches. This is about 5 feet, 9 inches. Yet, remember, this number varies. Some men will be taller, while some will be shorter.

Factors Influencing Height Growth
Genetics and height have a big influence on how tall a boy will grow. Things like his family’s height, any health issues, or diseases also matter. So do the food he eats and the world around him.
Genetics
Family plays a big part in how tall a boy will get. If the parents are short, their boy might be shorter too. Yet, if the parents are tall, their child could grow much more. Special conditions like Down syndrome or Cushing’s syndrome can affect height too.
Medical Conditions and Disorders
Health problems can also slow down growth. For instance, if the body doesn’t make enough growth hormone, a boy might not grow as tall. Long-term illnesses or not eating well when young can also stunt growth.
Nutrition and Environmental Factors
What a boy eats and his surroundings are important for his growth. Being too heavy or not eating right can change how fast a boy grows. It might even impact when puberty starts. Proper food, a clean environment, and being active make a big difference in how tall a boy will be.
| Factors | Impact on Height Growth |
|---|---|
| Genetics | Biological parents’ height, genetic disorders |
| Medical Conditions | Growth hormone deficiency, chronic illnesses, malnutrition |
| Nutrition and Environment | Obesity, access to nutrition, physical activity, toxin exposure |
Do boys grow taller after 17?
There’s no sure way to see how tall kids will be as adults. On average, a boy will reach his full height by the end of high school, around 18 years old. Most boys finish their growth by 16, but some might get a bit taller into their late teens. Boys usually grow the most from 12 to 15 years old. They often hit their biggest growth spurt by around age 16.
| Age | Growth Trend |

While there’s no set age when boys will stop growing taller, most finish major growth by their late teens. This means they have usually reached their adult height by 16 to 18. But, a few might keep growing, adding an inch or more, into their early 20s.
Growth Spurt and Puberty in Boys
Boys hit a growth spurt during their teenage years. As they grow, they also go through adolescent development. This phase brings about lots of physical changes. It’s key for parents and healthcare providers to understand these changes to help the boys.
Early vs. Late Maturers
When puberty starts can vary among boys. Some become early maturers, starting at about 11 or 12. Others, known as late maturers, begin a bit later, around 13 or 14. Although both groups gain the same amount of height on average, the late maturers grow faster to catch up.
Signs of Puberty in Boys
It’s easy to tell if a boy is going through puberty. Look out for a deeper voice and the growth of pubic, facial, and underarm hair. You’ll also notice their genitals getting bigger. Other signs include acne, stronger body odor, and body changes like gaining or losing weight. Soon after these, boys grow taller and build more muscle.
Conclusion
Most boys reach their adult height between 16 and 18. Some may grow taller into their late teens by an inch or more. Factors like genetics, health, what they eat, and the world around them play a role.
Understanding these factors and what’s common for boys can aid parents and doctors. They can help make sure a boy grows up healthy. The average adult male height in the United States is about 69 inches. But, every boy is different. It’s key to watch how your child grows to catch any issues early.
