I'm average size (5' 11"), but started with a 4 5/8" grip in the early 70s, and I've basically kept with that. I have an old Wilson Advantage with a 4 3/4" grip, and it feels comfortable, but it also weighs around 13.5 ounces. I've tried 4 3/8" grips, and they just don't feel right to me.
Edit: and I don't use an overgrip, just leather. Again, it is what I started with, and it just feels right to me.
