Most species of "Australopithecus" were diminutive and gracile, usually standing between 1.2 and 1.4 m tall (approx. 4 to 4.5 feet). There is a considerable degree of sexual dimorphism. Modern hominids do not show sexual dimorphism to the same degree — particularly, modern humans display a low degree of sexual dimorphism, with males being only 15% larger (taller, heavier) than females, on average.
