Why Are Some People Taller Than Others – 2022 Facts

Why Are Some People Taller Than Others

The world is filled with mystery, wonder, and unanswered questions. From why the sky is blue to why pandas are so cute, there are hundreds of unsolved questions about our world. And that extends to human height as well.

Why are some people taller than others? While it may not be a burning question you’ve pondered before, it’s one that many people have likely wondered about at some point in their life.

While some of us will grow up to be much shorter than our ideal height, others will tower above their peers. While this may seem like a simple genetic thing, there are actually quite a few factors that affect our potential height in adulthood.

The average height of a population can be used as a measure of health and nutrition. Taller people generally have better diets and access to healthcare, which is why in some countries, the average height is shrinking. But what exactly determines an individual’s height? Nutritionists and geneticists have conducted numerous studies on this subject to find out more about taller individuals.

Read on to learn more about why some people are taller than others and what factors impact your vertical length.

Reasons Why Some People Are Taller Than Others

There are a few different theories as to why some people are taller than others. The most obvious one is genetics. If both of your parents are tall, then there’s a good chance you will be too. However, this isn’t the only factor that determines height.

Another important factor is nutrition, with height being linked to the amount of protein consumed as a child. This can be seen in communities like the Inuit, where the average adult height is below 5’5” due to a lack of protein in their diet.

Another factor is health and access to medical care. Many diseases and infections cause stunted growth or keep children from reaching their full potential, preventing them from growing as tall as they could.

Another theory about why some people are shorter than others is that shorter people are more likely to survive than taller people in times of famine or food shortages. So, shorter people may have survived because they needed less food to survive, while taller people died because they needed more.

Factors That Impact Your Height


According to research, genetics account for approximately 80% of the variation in human height. Therefore, if both of your parents are tall, then there’s a good chance you will be too. If either of your parents is particularly short, you may be shorter than average too. However, genetics isn’t the only factor that determines how tall a person will become.

Nutrition and Health

Another theory about why some people are taller than others is that taller people are taller because they consumed more protein as children and teenagers, whereas shorter people didn’t consume as much.

This can be seen in places like the United Kingdom and Japan, where the average adult is 5’9” and 5’7” respectively. These places also have a particularly high amount of seafood in their diet, which is extremely rich in protein.

In contrast, the average American adult is only 5’9”. This is partly because an overwhelming majority of Americans consume a diet that’s low in protein.


Another theory about why some people are taller than others is that some ethnicities produce taller people than others. The average American adult is 5’9”, but there are certain ethnicities that are shorter than others. For example, African-Americans are generally shorter than other ethnicities, while Asian-Americans are generally taller.

Again, this is thought to be linked to diet and access to protein. African-Americans are more likely to eat a diet that’s low in protein, which can result in stunted growth. Asian-Americans are more likely to consume a diet that’s high in protein, which can result in them growing to a taller height.

This may seem like an obvious factor, but it’s important to cover it first. There are some noticeable differences between the average heights of men and women, but they don’t differ as greatly as you might expect.

Women tend to be around 10% shorter than men, with the average height of women being 162.5 cm and the average height of men being 175.5 cm. This isn’t a large difference by any means, and it isn’t always consistent.

There are countries where women are actually taller than men and vice versa. In some areas, such as in Northern Europe, women are significantly taller than men by as many as 10 cm.

One theory as to why this is the case is that the shorter men are more likely to enter high-risk professions, such as boxing and manual labor. Women, on the other hand, have historically pursued more low-risk occupations, such as nursing and teaching.

Body Composition

There is a significant difference in the average height of people who are overweight and those who are of normal weight. This leads many people to believe that diet and nutrition play a significant role in determining how tall you’ll be in adulthood.

Studies have shown that people who are significantly underweight or overweight in childhood tend to be shorter in adulthood than their peers. There are a few different theories as to why this is the case.

One theory is that malnutrition in childhood can lead to stunted growth. Another theory is that people who are overweight may have higher levels of certain hormones that inhibit growth and can lead to a shorter height.

The good news is that if you are shorter than you’d like to be, there is hope for you to grow taller than your peers. It can certainly be done, but you’ll want to make sure that you’re keeping a healthy diet and exercise routine to maximize your natural potential.

Fitness and Exercises

Another theory about why some people are taller than others is that some people are simply more active than others. Therefore, these people tend to be taller than those who sit around all day doing very little.

It’s also thought that people who do certain exercises are taller than others. For example, gymnasts and dancers tend to be quite tall, while swimmers tend to be shorter. There are two different theories as to why this is.

One is that dancers and gymnasts are simply more active than swimmers, which can encourage more growth. The other is that dancers and gymnasts tend to have a higher protein intake than swimmers, which can also encourage more growth.

Growth Spurt and Timing

Another theory about why some people are taller than others is that some people simply grow at a different rate and during a different time than others. Even if two people eat the same amount of protein, they may simply grow at different rates and different stages in their life. This can result in one person being significantly taller than the other.

At What Age Do We Stop Growing?

We’ve already discussed how some people grow taller than others and how genetics, diet, and health can affect height. But did you know that some people don’t stop growing until they’re in their 50s? Well, that’s the case for some people anyway.

There’s no specific age at which you stop growing, but there are certain factors that can result in your growth slowing down. For example, a poor diet and lack of exercise can result in a slowing down of your growth. This can be particularly common in adults.

What Can You Do to Grow Taller?

If you’d like to grow taller than your peers, you’ll want to follow a few key steps to maximize your potential.

First, you’ll want to make sure that you’re getting enough calories in your diet. While you don’t want to overeat, it’s important to make sure that you’re eating enough to provide your body with the nutrients it needs to grow.

You’ll also want to be sure that you’re exercising regularly. While you don’t have to be hitting the gym every day, you should be getting at least 30 minutes of moderate exercise each day.

These two things can make a significant difference in your height, and they’re also good for your health.
