Figure on 3 pieces per person, in my experience. Some people will eat 2, some 3, but there are always some guys who'll eat 4. I now very few people who stop at one. Depending on size of pizza and how many slices per, 2 or 3 pizzas for the adults. Better to have some leftovers for the rest of the week than only slice per person and some annoyed guests who think you're cheap.
This. Was at a kid's birthday party where there wasn't enough pizza. i had one slice, kid had one slice and DH had none. It was really bizarre that they didn't get enough.
