Men are taller than women because of sexual dimorphism. This is the scientific term used to describe the biological differences between males and females in the same species. Sexual dimorphism varies between species and in the case of humans, men are, on average, taller than women.
There is also a genetic reason for the height difference between men and women. Medical studies have found that there is a genetic variant in the X chromosome that can have an important role in determining the height of a man or woman.
Women have two X chromosomes, which means they are at much higher risk of being susceptible to this genetic variant. Researchers have found that a gene that is involved with cartilage development can be altered because of the genetic variant that is present in the X chromosome. Because they sometimes lack the ability to develop their bones and cartilage, women end up being much shorter than men.
Studies have also found that shorter women tend to have more children than women who are tall, while men who are considered average height tend to reproduce more than their shorter counterparts. This reproductive discrepancy has resulted in the height difference between men and women to increasing over time, due to evolutionary pressures.Learn More

Sufficient amounts of sleep coupled with a healthy diet of fruits, nuts, vegetables, meat and water help the body to produce an adequate number of growth hormones, as does deep breathing. However, human beings are rarely able to achieve any significant increase in height after puberty. Stretching exercises and leg-lengthening surgery may help increase height, but the latter is accompanied by serious health risks.Full Answer >
Female humans typically stop growing taller between 14 and 16 years old, while males typically stop growing between 16 and 18 years old. While these are the most common times to stop growing, they do not cover all cases.Full Answer >
