Globally, the average height for guys is a topic of interest, influenced by various factors from genetics to nutrition. Understanding these influences provides valuable insight into human growth and development. Let’s delve into the details of what contributes to the average height for men around the world and in the United States.
Average Height of Men Worldwide
According to the Centers for Disease Control and Prevention (CDC), the average height for men in the United States aged 20 and older is approximately 5 feet 9 inches. However, the global average height for men is slightly lower, around 5 feet 7.5 inches. This difference is primarily due to variations in genetics, environmental conditions, and nutritional standards across different countries.
The disparity in average heights can be attributed to the “averaging out” of heights between countries with taller populations and those with shorter populations. For example:
- The Netherlands boasts the tallest average male height, measuring approximately 5 feet 11.5 inches.
- East Timor records the shortest average male height, at around 5 feet 1.5 inches.
Here’s a snapshot of average male heights across 20 countries, based on research published in Economics & Human Biology:
| Country | Average Height in Men |
|---|---|
| Netherlands | 5 feet 11.5 inches |
| Australia | 5 feet 10 inches |
| Canada | 5 feet 10 inches |
| Jamaica | 5 feet 10 inches |
| United States | 5 feet 9 inches |
| Brazil | 5 feet 9 inches |
| South Korea | 5 feet 9 inches |
| France | 5 feet 8.5 inches |
| Egypt | 5 feet 8 inches |
| Fiji | 5 feet 8 inches |
| Israel | 5 feet 7.5 inches |
| Mexico | 5 feet 7 inches |
| Kenya | 5 feet 7 inches |
| China | 5 feet 6 inches |
| Afghanistan | 5 feet 6 inches |
| India | 5 feet 5 inches |
| Indonesia | 5 feet 5 inches |
| Peru | 5 feet 5 inches |
| Philippines | 5 feet 4 inches |
| Cambodia | 5 feet 3 inches |

Average Height of Men in the U.S. by Ethnicity
Within the United States, the average height for men also varies based on racial and ethnic backgrounds. The CDC data from 2016 provides a breakdown:
- Hispanic males: Approximately 5 feet 6.7 inches
- Asian males: Approximately 5 feet 6.8 inches
- Black males: Approximately 5 feet 9.1 inches
- White males: Approximately 5 feet 9.8 inches
These differences underscore the role genetics and ancestry play in determining individual height.
When Do Men Stop Growing?
Typically, males reach their full adult height around the age of 16, with only minor growth occurring in the subsequent one to two years. The most significant growth spurts happen during male puberty, driven by increased testosterone levels, primarily between the ages of 12 and 15. Understanding the timeline of puberty can help manage expectations regarding height development.
Historical Changes in Average Height
The average height of men has evolved significantly over the centuries. Factors such as overall population health, migration patterns, socioeconomic conditions, disease outbreaks, and genetic changes have all contributed to these shifts.
An Oxford University review illustrates how significantly height can fluctuate due to social and health factors. In Great Britain, historical records show:
- Roman Empire occupation (200-410 AD): 5 feet 3 inches
- Norman conquest (1066): 5 feet 7 inches
- Great Famine and Black Death (14th century): 5 feet 5 inches
- Early modern Britain (mid-1600s): 5 feet 7 inches
- Industrial Revolution (late-1700s): 5 feet 6 inches
- Great Britain in the 1970s: 5 feet 8 inches
These data highlight how societal and environmental factors profoundly influence human growth.
Tracking male height from 1896 to 1996, the Non-Communicable Diseases Risk Factor Collaboration (NSD RisC) compiled data reflecting significant changes:
| Year | Major Historical Event | Average Male Height |
|---|---|---|
| 1896 | Utah admitted as the 45th state | 5 feet 3.2 inches |
| 1906 | San Francisco earthquake | 5 feet 3.7 inches |
| 1916 | WWI: Battle of Jutland begins | 5 feet 4.1 inches |
| 1926 | Queen Elizabeth II born | 5 feet 4.6 inches |
| 1936 | Spanish Civil War begins | 5 feet 5 inches |
| 1946 | First V-2 rocket launched in the U.S. | 5 feet 5.4 inches |
| 1956 | Marilyn Monroe marries Arthur Miller | 5 feet 5.9 inches |
| 1966 | U.S. troops in Vietnam total 250,000 | 5 feet 6.2 inches |
| 1976 | Apple Computer and Microsoft founded | 5 feet 6.3 inches |
| 1986 | Chernobyl nuclear reactor meltdown | 5 feet 6.3 inches |
| 1996 | First flip mobile phone on sale | 5 feet 6.2 inches |
Factors Influencing Height
Genetics play a predominant role in determining height, accounting for about 80% of an individual’s stature. However, other factors also have a significant influence:
- Maternal Health: Poor maternal nutrition or exposure to toxins during pregnancy can lead to reduced stature in offspring.
- Malnutrition: Deficiencies in essential nutrients like zinc and iron during childhood can hinder growth.
- Socioeconomic Factors: Poverty and limited access to healthcare can impede growth due to untreated diseases during critical developmental stages.
Medical Conditions Affecting Height
Certain medical conditions can also impact a man’s height. These include:
- Gigantism: Conditions like pituitary adenomas, McCune-Albright syndrome, and neurofibromatosis can cause abnormally tall stature due to excess hormone production.
- Dwarfism: Various conditions can lead to abnormally short stature.
Conclusion
In summary, the average height for men globally is around 5 feet 7.5 inches, while in the United States, it’s approximately 5 feet 9 inches. While genetics are a primary determinant, environmental and socioeconomic factors also play crucial roles. Most men reach their full height by age 16. Understanding these factors provides a comprehensive view of what influences human height.
