I would assume taller women would perhaps like larger penis. I would assume this because the vagina opening goes up to the cervix. In a short woman, the cervix would be closer(because she is shorter of course). On a tall woman, the vagina may be longer, and she may like a little larger penis.There are large and small vaginas alike.
My girl is only 5'4". 7" is about as big as she would be able to handle without pain.
