What Percentage of Body Weight Is Bone?

According to the health monitoring device manufacturer Microlife, bones account for about 15 percent of total body mass in men. In women, bones account for roughly 12 percent of total body mass.

HealthStatus explains that the average adult has 206 bones. However, people can have a different number of rib bones and bones in their hands and feet, making the exact number of bones in the skeleton, let alone their weight, only a statistical average. Bone mass also depends on age and height, according to Microlife.

Tanita, a manufacturer of body composition analyzers, emphasizes that measured or estimated bone mass is not a viable indicator of bone strength and suggests consulting a specialist in case of frequent bone fractures or increased bone fracture risks.
