27. Allison Janney - 6'0
Janney said of her height in an interview with NPR: "I say I'm 5 feet 12 inches. I'm definitely 6 feet. In my heels I'm 6 feet 3 inches. ... [As a kid], I was always sort of a late bloomer in a lot of things. I always felt that way. I felt like my career started late and I think it was because of my height — and maybe some of my confidence issues."
