The most commonly used measurements regarding the size of vaginas come from Masters and Johnsonâs work from the 1960s. They looked at 100 women who had never been pregnant and found that vagina lengths, unstimulated, range from 2.75 inches to about 3Â¼ inches. When a woman is aroused, it increased to 4.25 inches to 4.75 inches.
The area between the opening of the vagina and the anus, below the labia majora, is called the perineum. It varies in length from almost 1 to more than 2 inches (2 to 5 centimeters). The labia majora and the perineum are covered with skin similar to that on the rest of the body.
