What is an average human nose size?

The average nose size for adult males is 5.8 centimeters and for adult females is 5.1 centimeters. The width of the human nose usually increases with age. Men's noses grow larger than women's beginning at puberty.

Nose size is the measurement from the paranasion, the area between the eyes, to the tip of the nose. The noses of males and females usually experience the same growth rate until age 11. This changes when puberty starts since boys' noses start to grow faster than girls'. A study by the University of Iowa states that the nose size of modern humans is smaller than for human ancestors, such as Neanderthals. This is because modern humans have less lean muscle mass.
