When we reach the age of 20, it often feels like we’ve crossed a significant milestone in our lives. It’s an age where many aspects of our physical development have stabilized, and for most, the relentless upward trajectory of growth that characterized our earlier years begins to taper off. One of the questions that frequently comes to mind at this juncture is, “What is the average height for a 20-year-old?” It’s a query that can be influenced by a multitude of factors, ranging from our genetic heritage and dietary choices to our geographic location. In this article, we will delve into the intriguing world of human height, exploring how various elements shape this characteristic as we reach the age of 20. Whether you’re simply curious about the subject or seeking to compare your own stature, you’ve come to the right place, as this article is here to provide you with the answers you seek. So, let’s embark on a journey to understand what’s typical for 20-year-olds across different regions of the world and unravel the reasons behind the variations in height among individuals.

What is the average height for a 20-year-old?

In the United States, the average height for 20-year-old men typically hovers around 5 feet 9 inches, or approximately 175.3 centimeters.

For 20-year-old women in the United States, the average height is typically around 5 feet 4 inches, or approximately 162.6 centimeters.


What are the factors that affect the height of a 20-year-old?

Genetic inheritance

An individual’s ultimate height at the age of 20 is primarily shaped by the genetic inheritance received from their parents. If a significant number of family members are tall or short, the 20-year-old will likely exhibit a comparable growth pattern.

Nutritional intake

A 20-year-old needs to eat a balanced diet that includes plenty of calcium, protein, and vitamins to aid in their growth and development if their growth plates haven’t closed.

Health and medical history

If a 20-year-old has had major illnesses or medical conditions, it might affect their growth. Regularly being sick can interfere with their proper development.

Physical activity levels

Regular play, sports, and exercise stimulate growth hormones that can affect a 20-year-old’s height by strengthening their bones and muscles.

Sleep patterns

Ensuring an adequate amount of sleep is not only crucial for feeling well-rested but also plays a significant role in supporting the body’s efficient production of growth hormones. Growth hormones, such as human growth hormone (HGH), are released primarily during deep sleep stages, particularly in the early part of the night.

Socioeconomic factors

A 20-year-old’s access to quality food, healthcare, and living conditions, which are influenced by their socioeconomic status, can affect their growth and physical development.

Stress levels

Chronic stress can lead to metabolic changes, including alterations in appetite and eating patterns. Some people may turn to emotional eating, leading to weight gain, while others may experience reduced appetite, potentially affecting their overall nutritional intake. These metabolic shifts can have repercussions on growth, as adequate nutrition is essential for proper development.

Ethnic background

The average height of a 20-year-old can be influenced by their ethnicity, as certain genetic factors linked to height tend to vary across different ethnic groups.


A 20-year-old’s height can be affected by the geographical area they grow up in, as environmental aspects, like climate, altitude, and regional dietary habits, can shape growth patterns.

Can you grow taller at 20 years old?

The answer is yes. Some individuals can grow taller at 20 years old, but it is relatively uncommon. Most people reach their maximum height by the time they are 18 years old, following the closure of growth plates in their bones. The cartilage growth plates, also called epiphyseal plates, are found close to the ends of long bones. These plates are active during adolescence, which permits the growth of bones and a rise in height.

However, in some cases, a person’s growth plates may not close until their early twenties, allowing for additional growth in height. This is more likely to be the case for men than women, as men typically continue growing for a longer period during adolescence.

For any concerns or questions about growth and development, consulting a healthcare professional is the best course of action. They can provide personalized information based on an individual’s specific health and developmental history.

How to grow taller or look taller at 20 years old?

Maintain a healthy diet

Proper nutrition is crucial for overall health, including maintaining your height. Ensure your diet includes adequate calcium, vitamin D, protein, and other nutrients essential for bone health.

Regular exercise

Regular physical activity, including stretching, yoga, and strength training, can improve posture, which can make you appear taller. Activities, like swimming and basketball, are also often recommended.

Good posture

Keeping your posture correct can greatly improve the way you look. Having your head held high and shoulders back can quickly make you appear taller and more self-assured whether standing or sitting upright.

Adequate sleep

During deep sleep, the body releases growth hormones. Ensuring you get enough quality sleep can help in maintaining your health, which indirectly affects your stature.


Proper clothing choices

Wearing clothes with vertical stripes, monochromatic color schemes, or high-waisted trousers can create an illusion of height. Also, well-fitted clothes, as opposed to very loose ones, tend to make you look taller.


Shoes with thicker soles or a slight heel can add inches to your height. There are also insoles available that can be inserted into shoes for an extra height boost.

Hair and makeup tricks

Certain hairstyles can make you appear taller. For example, keeping your hair shorter on the sides and taller on top can elongate your face. For those who use makeup, techniques, like contouring, can also create the illusion of a longer face.


Often, how tall you appear can be influenced by how you carry yourself. Confidence can make a significant difference in your overall presence.

Take supplements

Taking additional vitamins can assist with growth at the age of 20. Even with a healthy diet, sometimes our bodies need extra support. Consulting a doctor is important to determine which vitamins are necessary for optimal growth. It’s crucial to choose safe vitamins from reputable brands and to speak with a doctor or an adult before starting any supplements, ensuring they are suitable for you.

In conclusion,

At 20, while some individuals may still experience slight increases in height, others have reached their full adult stature. This variation in growth patterns highlights the diverse nature of physical development. The average height for a 20-year-old is influenced by multiple factors, like genetics, nutrition, and environment, emphasizing the uniqueness of each person’s growth journey. Remember, height is just one aspect of an individual’s identity and doesn’t define overall health or ability. For those concerned about their growth or development, seeking advice from a healthcare professional is always recommended.
