This is a simple one: NEVER roll it. Rolling is bad.
A) It's hard to control the shape of a pizza dough that way.
B) Worse, it presses all of the air out of the dough. You end up with a flat, dense crust, which is not what you want.
Instead, use a floured board and your hands.
1) Flatten the dough ball with the palm of your hand.
2) Using both palms, start pressing and stretching the dough ball on the board until it's wide enough to pick up with both hands.
3) Using the knuckles of both hands, get under the rim of the dough and start stretching it until it is the size you desire.
It takes a little practice. But you get a much better, rounder pizza. (I'll see if I can post a video of this process.)
