The average height of a man varies depending on several factors such as age, race, genetics, and geographical location. However, based on the most recent global data available, the average height of an adult man is around 5 feet 7 inches or 170.18 centimeters.

According to the World Health Organization (WHO), the average height for adult males varies across different regions of the world. In North America and Europe, the average height for adult males is around 5 feet 10 inches or 177.8 centimeters. In Asia and South America, the average height is slightly shorter, around 5 feet 6 inches or 167.6 centimeters. In Africa, the average height for adult males is around 5 feet 4 inches or 163.8 centimeters.
However, it is important to note that these numbers are only averages and there is significant variability in height across the male population. Additionally, the average height can change over time due to factors such as changes in nutrition and health status.
When considering whether a height of 5 feet 7 inches is average for a man, it is important to look at the specific population being considered. For example, in the United States, the average height for adult males is around 5 feet 9 inches or 175.3 centimeters. In the United Kingdom, the average height for adult males is around 5 feet 10 inches or 178 centimeters. In Japan, the average height for adult males is around 5 feet 7 inches or 172.6 centimeters.
It is also important to consider the age of the male being considered. Height tends to increase during childhood and adolescence and then stabilizes in early adulthood. Therefore, the average height of a man will depend on the age range being considered.
In summary, while the average height of an adult male varies across different regions of the world, based on global data, the average height is around 5 feet 7 inches or 170.18 centimeters. However, there is significant variability in height across the male population, and the average height can change over time and depending on the specific population being considered.
