I'm a little shorter than you are at 5'5" so I was just inside the height range for a short. But in the end I decided on a regular and I'm happy with it. I was worried that if I went with the smaller quilt I might have to stretch it to full length to fit and that that might compress the down slightly. The regular is probably a little longer than I need but not so you'd notice. When I sleep in it it seems just right.
