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.
As you mentioned, for some women, the depth from the vaginal opening to the tip of the cervix is 3 to 4 inches when they are not sexually aroused. Other women may have a vaginal depth of five to seven inches. Regardless, during arousal, blood flows to the genital area, and sexual excitement causes the upper two-thirds of the vagina to lengthen by forcing the cervix and uterus to ascend. The vagina also lubricates to help ease penetration.
