The composition of the average human man can be broken down into a series of specific physical measurements and statistics—some of which might surprise you. For example, an average man's head is about 7% of his body weight. That means the average man with a weight of 172 pounds has a head that weighs more than 12 pounds!

By identifying these standard stats and measures, some health issues can be more easily identified when a specific measure skews outside of these averages; however, also being averages, variations do not necessarily mean there is a health issue.
