Average Height Statistics in South Korea
Recent data from South Korean government surveys provide a clear picture of the average height across different age groups. The 8th Korean Body Measurement Survey, released in 2022 by the Korean Agency for Technology and Standards (KATS), is one of the most reliable sources. This study collected data from thousands of Koreans aged 20 to 69 between 2020 and 2021.
Official Survey Data from KATS
According to the KATS 2022 report:
- The average height for men was 172.5 cm (approximately 5 feet 8 inches).
- The average height for women was 159.6 cm (approximately 5 feet 3 inches).
These figures represent a significant upward trend compared to surveys from 40 years prior. The 1979 survey, for example, recorded an average male height of 166.1 cm and a female height of 154.3 cm. This indicates that Korean men grew an average of 6.4 cm and women grew 5.3 cm over that period.
Comparison by Age Group
Height can vary slightly between different age brackets, often reflecting the improvements in nutrition and public health over time. Younger Koreans, for instance, often show a slightly taller average height than their older counterparts. For example, a 2024 report citing World Population Review data noted that the average height for 19-year-old boys was 175.52 cm and for 19-year-old girls was 163.23 cm. These figures suggest that the younger generation is continuing the upward trend in physical stature.
Factors Contributing to Height Increase
The dramatic increase in the average Korean height over the past half-century is not a matter of a sudden genetic change. Rather, it is a powerful demonstration of how environmental factors can influence physical development, even in a genetically homogenous population.
Economic Development and Improved Nutrition
Since the mid-20th century, South Korea has undergone rapid economic growth and industrialization. This progress has led to a major improvement in living standards and, critically, in national nutrition. During the post-Korean War era, the country faced widespread poverty and food insecurity. With economic prosperity, access to a diverse and calorie-rich food supply became commonplace. A well-nourished child is more likely to reach their full genetic height potential compared to a child with a poor diet, inadequate healthcare, or high exposure to disease.
The Role of Genetics vs. Environment
While genetics are a primary determinant of an individual's potential height, environmental factors act as the crucial moderator. This is strikingly illustrated by the height difference between North and South Koreans. Despite sharing a common genetic background, North Koreans are, on average, significantly shorter than South Koreans. Some studies have found a difference of several centimeters, with one showing North Korean men to be approximately 8 cm shorter than their South Korean peers, a disparity largely attributed to vast differences in nutrition and economic well-being. In countries with strong nutrition and healthcare systems, a population's genetic potential for height is more fully realized.
Lifestyle Changes and Health
Beyond basic caloric intake, changes in lifestyle and public health have also played a role. Improved sanitation, advanced medical care, and better overall childhood health reduce the burden of diseases that can stunt growth. Furthermore, a shift in dietary patterns, with increased consumption of proteins and other essential nutrients, has supported the growth spurt observed over recent decades. Height, in this context, is a proxy for overall societal well-being.
International Comparison and Global Context
Comparing Korean average heights to other countries provides important context for understanding these trends. While Korean average height has increased rapidly, the trends vary across the globe based on factors like economic status and public health infrastructure.
A Global Height Comparison Table
| Country | Average Male Height (cm) | Average Female Height (cm) |
|---|---|---|
| South Korea | ~172.5 cm | ~159.6 cm |
| Netherlands | ~183.8 cm | ~170.7 cm |
| United States | ~175.5 cm | ~162.2 cm |
| Vietnam | ~165.6 cm | ~154.5 cm |
| North Korea | ~165.6 cm | ~154 cm |
Note: Data from various sources, including World Population Review and national surveys, reflecting recent available statistics. Values are approximate and may vary depending on the specific age groups and survey methodology.
This comparison highlights how average height can differ dramatically between genetically similar populations due to economic and nutritional disparities (e.g., North and South Korea). It also shows that despite significant growth, South Koreans are not among the world's tallest populations, a distinction often held by European nations like the Netherlands.
Evolving Body Shapes
Alongside the increase in height, the KATS survey also noted changes in other bodily measurements, such as Body Mass Index (BMI). The report indicated that Korean men's average BMI has steadily risen over the past decades, while women's has also changed, albeit with different trends across age groups. These shifts indicate a broader transformation of the Korean physique, reflecting evolving dietary habits and modern lifestyles.
The Societal Impact of Increasing Height
This rise in stature has had practical implications for Korean society, influencing everything from the design of clothing and furniture to housing. For instance, the demand for redesigned everyday items to accommodate taller individuals is a direct result of this physical shift. Culturally, height can be a sensitive topic, and the rising average height has altered societal perceptions, though preferences for height in relationships remain consistent among some demographics.
The significant increase in the average height of Koreans is a testament to the powerful impact of improved living standards, nutrition, and public health on human physical development. It serves as a compelling case study on the interplay between genetics and environmental factors in shaping a population's stature. While genetics provides the blueprint, a nation's well-being and prosperity determine how fully that potential can be realized.

Conclusion: A Taller and Healthier Population
In conclusion, the average Korean man stands at approximately 172.5 cm and the average Korean woman at 159.6 cm, based on 2022 data. This growth is a modern phenomenon, primarily driven by rapid economic development and subsequent improvements in diet, sanitation, and healthcare. The stark contrast in height between North and South Koreans, who share a common genetic ancestry, further solidifies the role of environmental factors. The trend of increasing height is likely to continue in the younger generations, underscoring South Korea's transition into a high-income, developed nation. This is a story not just about height, but about a nation's journey towards better health and greater prosperity.
