The average height of white men varies depending on a number of factors, including age, ethnicity, and geographic location. However, there are some general trends that can help provide an estimate of the average height of white men in different parts of the world.

In the United States, for example, the average height of adult white men is around 5 feet 9 inches (175.3 cm). This is based on data collected by the Centers for Disease Control and Prevention (CDC) as part of the National Health and Nutrition Examination Survey (NHANES). The data shows that the average height of adult men in the US has been fairly stable over the past few decades, with only small variations from year to year.
In Europe, the average height of white men can vary quite a bit depending on the country. For example, in the Netherlands, the average height of adult men is around 6 feet (183 cm), making them some of the tallest men in the world. Other countries in northern and central Europe, such as Denmark, Norway, Sweden, and Germany, also tend to have relatively tall populations, with average heights of around 5 feet 11 inches (180 cm) or taller. In contrast, countries in southern Europe, such as Italy, Spain, and Greece, tend to have shorter populations, with average heights of around 5 feet 7 inches (170 cm) or less.
It is worth noting that height can vary greatly within populations due to factors such as genetics, nutrition, and lifestyle. Additionally, height can also be influenced by socioeconomic factors such as income and education, as well as cultural attitudes towards height and body size. For example, some studies have found that people who grow up in wealthier households tend to be taller than those who grow up in poorer households, possibly due to differences in access to nutritious food and healthcare.
In terms of ethnicity, the average height of white men can also vary depending on the specific group. For example, white men of northern European ancestry tend to be taller than those of southern European ancestry, as mentioned above. Additionally, white men of certain ethnicities, such as those of Ashkenazi Jewish or Dutch ancestry, may have higher average heights due to genetic factors.
Overall, while it is difficult to give a precise answer to the question of how tall the average white man is, data from various sources suggests that the average height of adult white men in the US is around 5 feet 9 inches (175.3 cm), with some variation depending on age, ethnicity, and other factors. In other parts of the world, such as Europe, the average height of white men can vary quite a bit depending on the country. However, it is important to remember that height can vary greatly within populations, and should not be used as a measure of worth or value.
