If you are not sure when your growth curve is going to stop, this post will help you understand the height progression curve and when it ends.

How many growth spurts do boys have?

The endocrine and nervous systems are the major mediators of growth. The hypothalamus at the base of the brain contains nerve cells that produce regulatory hormones that affect many aspects of growth, reproductive development, and metabolism.

From the age 4 until adolescent growth spurt, the average rate of growth for boys is about 6-7cm/year. At teenage growth spurt, everything grows in little spurts. However, if we have to be considerate of height only, then the majority of boys have 2 main growth spurts with smaller growth spurts in between.

Is there a male height growth age limit?

Usually, males grow very fast between the ages of 10-16, and during this growth Spurt, the increase in height can be as much as 12 inches (25 cm).

After crossing 16 years, the increase in high is slow, and the boy will stop growing between the ages of 18 to 20. This is the age whereby the majority of boys reach their final growth.

However, there are a few cases where boys continue to grow till 21 years or even 25 years.

When do boys stop growing:

Growth can be measured in different ways. Different parts of the body grow in a different way for both women and men. Here’s more on different parts of the body in young males starting with the feet and legs.

For feet

Usually, the feet stop growing a few years after puberty. For example, in girls, the average age of feet to stop growing is around 14 years, while in boys, it is about 16 years. However, the final growths of feet plates occur between 18 years to 20 years of age.

Your feet will technically stop growing when you are a teenager, but they will continue to change size throughout adulthood life.


Since puberty ends at different ages for many people, there is no definite age at which the penis will have undergone complete growth. Generally, puberty can take up to 4 years, and during this stage:

  • The penis and testicles start to grow in size at the beginning of puberty.
  • The genitals continue to grow for a further 1 year.
  • Towards the end of puberty, the growth of the penis and other genital parts should be complete.

Hair Growth

Pubic hair grows during the puberty stage. As stated earlier puberty stage may last up to 4 years.  Pubic hair is usually the first hairs on the body to grow, then underarm hair after about a year. Facial hair and other body hair will usually grow after around 2 years of puberty. The growth of hair on the various body parts of boys usually stops at the end of puberty.

Factors that might impair growth rates

  • Illnesses
  • Genetic conditions
  • The use of medications, such as corticosteroids, can limit growth.
  • Hormonal imbalance
  • Diet
  • Environment

Factors that affect growth and development


Hereditary factors generally influence growth and development in men because it’s the genes that carry information about how a person should grow and develop. Genes determine a person’s physical and behavioral developments that normally occur throughout the entire life. Examples include things such as height, weight, facial features, intelligence, breast size, hip size, and hair and eye color.


Individual sex orientation is a crucial factor that influences growth and development in men. Generally, there is usually a substantial observable difference in the growth and development of young boys and young girls, especially during the teenage period. Often the physical growth of boys is slower than that of girls. Generally, the body structure and growth of boys is different from that of girls.


Various studies have shown that race, to a greater extent, influences growth and development in people. Race influences weight, color, and height and body structural build-up of an individual. An individual’s body development and growth show a difference with varied cultural groups.

For example, a child of the black race will be black, their hair color, facial structure, and eye color. Growth spurts in black people are slower than those of white people.


Hormones are usually regarded as growth supporting components because they play an essential role in regulating the process of growth and development. There are many endocrine glands within our body system. When these hormones are directly released into the bloodstream, they can lower the activity of body organs such as growth.


Growth and development have a direct relation to nutrition. During different phases of growth and development, the body requires varying quantities of calories for normal growth.  In many cases, the cause of slow growth in children is malnourishment. There are 9 amino acids, which are very crucial for the growth and development of an individual, in which case the absence of any one of them will result in stunted growth.

Also, other mineral elements are essential in facilitating growth, and some of them include phosphorous, zinc, iodine, calcium, and vitamins. These mineral elements can only be available in the body through proper nutrition.

Social-Economic factors

For a very long time, it has been observed that children from different socio-economic levels vary in average size at all ages.

Children from upper families grow faster than those from lower social, economic levels because of regular meals, sleep, and exercise. Also, in families with high-level income, some children usually do not undergo proper nutrition, and this affects their growth and development.

Maintain your BMI

Avoid eating too much food

Avoid eating too much food, as these slow the digestion process and makes it difficult for your body to assimilate the necessary nutrients that are necessary for growth.

Boosting your immunity

The body’s immune system plays an important role in the development and growth process. A strong immune system blocks diseases from interfering or slowing down the growth process.

Maintain a good posture always

Maintaining a slouching posture regularly inhibits your height growth by putting too much pressure on the spinal cord. Maintaining a straight posture with your head and spine contributes effectively towards increasing your height.

Understanding factors other than genetics that determine your height

Science has shown that genetics determine 70% to 80% of a person’s height. However, the remaining percentage is determined by factors other than genetics, and such factors include diet, lifestyle, and other external factors.
