How Deep Is the Average Vagina? On average, the vagina is 3 to 4 inches deep during un-arousal periods, although some women have a vagina that is around 5 to 7 inches deep. As a woman becomes aroused, the vagina expands: as blood flows to the area, the cervix and uterus are pushed up by the upper two-thirds of the vagina to create more space.
