I think torso length and hip width are pretty good determiners for vagina size. It is not the height of of the women (head to foot) which determines the depth of the vagina. There is definitely a racial difference and also genetic factors which determine the length of vagina. White women give birth to babies with larger heads "on average" so their hips are "on average" broader, and their vaginal opening is also larger. Black women, actually have smaller vagina's. They give birth to babies with smaller heads and have smaller hips. Black women store more body fat on their buttocks, but their hips are actually smaller (men and women). White people also have longer torso's and white women also have longer vagina's. Asian women have shorter vagina's than both black and white women, have wider openings than black women, but not as large as white women. Unlike penis size, the body size/shape of a woman has an influence on vaginal size. Taller women (longer torso) with wider hips will most likely have longer and deeper set vagina. Torso size/length is more significant than actual height. As for men however, a 6' 8" man may have a smaller penis than a 5' 8" man, just like has ears may also be smaller. External organs are not influenced by body size or height, whereas internal organs are.
