What is the tallest a women will grow by the age of 20?

By the age of 20, most women typically reach their maximum height, which is generally between 5 feet and 6 feet (152 to 183 cm). Height growth usually occurs during adolescence, with a significant growth spurt happening around the onset of puberty. While genetics play a crucial role in determining height, factors such as nutrition and overall health can also influence growth patterns. After age 20, significant height increases are uncommon as growth plates close.
