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.
In a non-pregnant woman, the cervix is usually 2 to 3 cm long (~1 inch) and roughly cylindrical in shape. The narrow, central cervical canal runs along its entire length, connecting the uterine cavity and the lumen of the vagina.
