How tall is the average man?

Human height is regulated by many factors. Since the development of modern medicine and plentiful nutrient-rich food in the developed world average height has increased dramatically. Nutrition is the most important factor in determining height; and height records from military records and other documents can be used to quite accurately compare nutrition and height in various eras. Evidence has shown that height decreased in Britain in the early nineteenth century, before beginning its long increase around mid-century. Increase in height has not been constant, however. The European Middle Ages was an era of tallness with men of above six feet (1.83 m) considered unremarkable. In Europe human height reached its nadir at the start of the nineteenth century. Until the general rise in human health, as urbanization increased, the accompanying trend was a height decline.
