Examining Trends in Average Male Height Over Time

Height is an easily quantifiable measure of growth and development. Tracking height trends over time can provide insight into nutrition, healthcare access, and even economic conditions. For men in particular, average height has steadily increased in many parts of the world over the past century or more as nutrition and health standards have improved.

The Significance of Average Male Height

Why does average male height matter? Height is associated with health, longevity, and even earnings. Taller people are less likely to suffer from heart disease and more likely to earn higher wages according to some research. Understanding trends in men's average height can highlight progress in living standards.

Height is also linked to confidence and social dominance to some degree. Though the relationship is complex, studies show taller men report higher self-esteem and more professional success on average.

Worldwide Increases in Average Male Height Over the Past Century

Data shows average heights for men have risen substantially worldwide over the past 100-150 years. For example, American men averaged around 5'7" at the turn of the 20th century. Today the average American male height is about 5'9".

Similar gains occurred across Europe, Asia, and other regions. Experts attribute most of this growth to improved nutrition from globalization of food supplies and rising incomes. Access to healthcare, decreasing rates of infectious diseases, and other societal changes also allowed people to grow taller.

Examining Average Height Trends by Country

While almost all populations witnessed increases in average male height over the past century, differences remain between countries tied to economic factors.

Developed Countries: Steady Increases Over Time

Most wealthy, industrialized nations saw strong, steady rises in men's average height as the 20th century progressed. For example data shows:

  • Average male height in France increased from around 5'5" in 1914 to 5'9" by the early 2000s
  • In South Korea average height among adult men grew from 5'4" in 1945 to 5'9" in modern times
  • Men in Sweden averaged just under 5'7 in 1907 compared to almost 5'11" today

Good access to healthcare, nutrition, sanitation and low rates of poverty and disease allowed most populations in industrialized economies to reach their growth potential.

Developing Countries: Accelerating Gains More Recently

Poorer and developing countries began witnessing comparable surges in men’s average height more recently as their economics modernized post World War 2. For example since the mid 20th century:

  • Average male height in Turkey increased from 5'4" in the late 1940s to 5'8" as of 2020
  • Iranian men averaged around 5'3.5" in the 1960s-70s but now average 5'7" in height
  • From the 1990s to today the average height among men in South Asia grew from 5’3” to over 5’6”

Overall unprecedented economic growth enabled better nutrition and living standards across much of the developing world which helped increase male heights.

Projecting Future Trends in Men's Average Height

Will men continue getting taller indefinitely? Experts suggest average heights may plateau in the not too distant future, especially in developed countries. However some nations still have room for further growth catch-up.

Limits to Indefinite Increases

There appears limits to how tall the average man can grow to be. As populations meet their biological potential, average heights level off. For example data showed northern/central European men seemed to cap out around 6’1” on average.

Likewise East Asian populations also appear approaching their maximum averages based on genetics and ethnicity. Experts suggest most well-fed, healthy populations likely have just 1-2 more inches of growth potential at this point.

Developing Countries: More Gains Possible

At the same time some developing regions seem to still have growth rebound potential. Areas of South America, Africa and South Asia in particular lagged in height gains the past century due to poverty.

As their economies emerge further experts predict average male heights approaching European/North American averages. Though genetics imposes final limits, developing countries have more room for catch up growth as conditions improve.

In conclusion average male heights rose substantially worldwide the past ~100 years but began leveling off recently for richer countries. Further economic gains in still-poor nations can help more populations achieve their biological height potentials in the coming decades.


Why has average male height increased over time?

Average male height has steadily increased over the past century primarily due to improved nutrition, healthcare access, lower rates of disease, and higher incomes allowing people to fully grow to their biological potential.

Which countries have seen the biggest gains in average male height?

While almost all countries saw increases, some of the largest gains occurred in rapidly developing economies like South Korea, Turkey, and Iran as well as in historically poorer regions like South Asia.

What limits further increases to average male height?

Genetics and ethnicity impose final limits on potential average height within a population. As economies industrialize and maximize living standards, average heights plateau around 6'1" for European/North American descent groups for example.

Will developing countries continue to see increases in average male height?

Yes, experts predict developing regions lagging economically like Africa and South Asia still have potential to catch up to averages in richer nations, conditional upon continued advancements in their nutrition and reductions in poverty.
