5'6"
When I was measured for recent surgery and according to my medical records, I've shrunk 1" in height over the past 20 years (I'm 43 now) including over 10 years on estrogen etc.
I used to be almost exactly the same height as a dear friend who I've known for over 25 years, but now I feel quite little compared to him. To be expected, really. So that puts me a little bit above the average women's height, I guess. Still wear heels to work though.
