I'm currently using a 5.0 inch LG bello, and that seems to be the perfect size for me. When I had a smaller phone, I didn't like it and it was too small for my hands, and it just felt silly. The Bello's screen is large and everything can be seen perfectly even from a distance, though the resolution could be a little higher. That's the only drawback, currently. I hate those phones that are huge, however. I don't want to go around carrying a laptop to my ear. Not literally, of course.
