When Do Men Stop Growing

Last Updated on September 20, 2023 by Chase Reiner

Most men stop growing in height around the age of 18, but some may continue to grow into their early 20s. This is because the growth plates in the bones, which allow for bone growth, typically fuse around this age.

When Do Men Stop Growing?

For many young men, physical growth is a significant part of their transition into adulthood. But when does this growth spurt actually end? Here, we present a comprehensive list of when men actually stop growing.

  1. During Puberty: The most substantial growth phase for men occurs during puberty, which typically starts between ages 12 and 16. During this period, the production of testosterone increases significantly, leading to rapid physical changes, including growth in height.
  2. Around the Age of 18: The majority of men stop growing around the age of 18. However, growth can extend into the early 20s in some circumstances. It mostly depends on genetics and the individual’s overall health.
  3. Late Teens for Growth Plates: By the late teens, most men’s growth plates, areas of developing cartilage where growth occurs, begin to close. Once these growth plates are closed, further increase in height is unlikely.
  4. Early 20s for Muscle Development: In men, muscle development typically continues into the early 20s. While this is not directly related to height, it can contribute to the overall perception of growth and physical maturity.
  5. Mid-20s for Brain Growth: Men’s brains continue to grow and develop well into their mid-20s. This cognitive growth can significantly impact behavior, decision-making, and emotional maturity.

Let’s take a look at this in a tabulated form:

Growth PhaseTypical Age Range
Puberty12-16 years
General Height GrowthUp to 18-20 years
Growth Plate ClosureLate Teens
Muscle DevelopmentEarly 20s
Brain DevelopmentMid 20s

While it’s important to note that exceptions exist, the pace at which a man grows often varies based on individual genetic, nutritional, and environmental factors.

Overall, while physical growth may cease after the teen years, personal growth continues throughout a person’s lifetime. This ongoing growth is reflected through developing emotional intelligence, accruing life experiences, and continuing to learn and adapt. Remember, “growth” is not just about the physical aspect; mental and emotional development are equally important.

8 Factors for Growth & Height of Men

Several factors influence the growth and height of men. Here are eight key factors explained in detail:

  1. Genetics: Genetics plays a crucial role in determining a person’s height. Height-related genes inherited from parents largely determine an individual’s potential for growth. If both parents are tall, it’s more likely that their offspring will be taller.
  2. Nutrition: Adequate nutrition, especially during childhood and adolescence, is vital for proper growth. A balanced diet with essential nutrients, including protein, calcium, vitamin D, and micronutrients, supports bone development and overall height.
  3. Hormones: Hormones, particularly growth hormone (GH) and insulin-like growth factor 1 (IGF-1), are essential for growth. These hormones stimulate cell growth and division, influencing bone length and overall height. Any hormonal imbalances can affect growth potential.
  4. Sleep: Quality sleep is crucial for growth and height. During deep sleep, the body releases growth hormones, promoting tissue and bone growth. Adolescents, in particular, need sufficient sleep for optimal growth.
  5. Physical Activity: Regular physical activity and weight-bearing exercises can support the development of strong and healthy bones. Engaging in sports and exercise during growth years can positively impact height.
  6. Health and Illness: Chronic illnesses, malnutrition, or severe health conditions during childhood can stunt growth. It’s essential to address and manage health issues promptly to mitigate their impact on height.
  7. Environmental Factors: Environmental factors like exposure to pollutants, toxins, and living conditions can influence growth. A healthy and safe environment promotes overall well-being and, indirectly, height.
  8. Puberty Timing: The timing of puberty can affect growth. If puberty starts earlier or later than average, it may impact the growth spurt that usually occurs during adolescence. Late bloomers may continue growing into their late teens.

Is there anything you can to do influence your growth or height?

There is not much you can do to influence your growth or height once you have reached adulthood. However, there are some things you can do during childhood and adolescence to maximize your growth potential:

  • Eat a healthy diet. A healthy diet is essential for overall growth and development. Make sure to eat plenty of fruits, vegetables, whole grains, and lean protein. Avoid processed foods, sugary drinks, and excessive amounts of saturated and unhealthy fats.
  • Get enough sleep. Sleep is essential for growth and hormone production. Children and adolescents need between 8 and 10 hours of sleep per night.
  • Engage in regular physical activity. Physical activity helps to strengthen bones and muscles and can also promote growth. Aim for at least 60 minutes of moderate-intensity physical activity most days of the week.

If you are concerned about your height, talk to your doctor. They can assess your growth and development and make sure that there are no underlying medical conditions that are affecting your height.

Here are some additional tips that may help to maximize growth potential:

  • Maintain a healthy weight. Being overweight or underweight can interfere with growth.
  • Avoid smoking and drinking alcohol. Smoking and drinking alcohol can stunt growth.
  • Manage stress. Stress can interfere with hormone production and growth.

If you are still growing, following these tips can help to maximize your growth potential. However, it is important to remember that genetics play a major role in height, so there is no guarantee that you will reach a certain height, even if you do everything right.

When do boys get a growth spurt?

Boys typically experience a growth spurt during adolescence, which can vary in timing and duration. Here’s a detailed explanation:

  1. Onset of Puberty: The growth spurt in boys is closely linked to the onset of puberty. This usually occurs between the ages of 9 and 14, with an average age of around 12. However, it can vary widely from individual to individual.
  2. Tanner Stages: Puberty is often categorized into five stages known as Tanner stages, with Stage 1 representing pre-puberty and Stage 5 indicating full maturity. The growth spurt typically begins during Tanner Stage 2 or 3 for most boys.
  3. Peak Growth: The most rapid phase of growth occurs during Tanner Stage 3 or 4, usually between ages 12 and 16. Boys can grow as much as 4 inches (10 centimeters) or more per year during this period.
  4. Duration: The duration of the growth spurt varies among individuals. It can last for about two years on average, but some may experience a shorter or longer growth spurt.
  5. Individual Differences: Factors such as genetics, nutrition, overall health, and hormonal balance influence the timing and intensity of the growth spurt. Boys who start puberty earlier often have an earlier growth spurt, while late bloomers may experience it later.
  6. Peak Height Velocity (PHV): PHV is the term used to describe the maximum rate of growth during the growth spurt. It typically occurs around age 14 for most boys but can vary. During PHV, boys can gain 3-4 inches (7.5-10 centimeters) or more in height per year.
  7. Growth Plate Closure: Growth plates in the bones fuse and close as a person reaches the end of their growth phase. In males, this process often completes by around age 16 to 18. Once the growth plates close, the potential for further height increase diminishes significantly.
