The country with the tallest females on average is the Netherlands. According to a 2019 study by the Journal of Epidemiology and Community Health, the average height of adult women in the Netherlands is 5 feet 6.5 inches (169 cm), which is taller than the average height of women in any other country.

There are several factors that contribute to the relatively tall stature of Dutch women. One of the main reasons is genetics. The Dutch population has a high frequency of the “tall” gene, which is responsible for increased height. Additionally, the Dutch diet is rich in dairy products, which contain calcium and other nutrients that are important for bone health and growth. The Dutch also have a tradition of cycling, which promotes physical activity and can contribute to overall health and height.
It’s worth noting that while the average height of women in the Netherlands is the tallest in the world, there is still a wide range of heights within the population. Other countries, such as Latvia and Estonia, also have relatively tall female populations, with average heights of around 5 feet 6 inches (168 cm).
Overall, the height of individuals is influenced by a variety of factors, including genetics, nutrition, and lifestyle. While the Netherlands has the tallest female population on average, height can vary widely within any given country based on these factors.
