Depends on the pizza, since some are much thicker and more substantial than others.
I'm going to talk about proportions since in theory, a pizza could be cut into any number of slices or worse, squares.
If a CPK (California Pizza Kitchen) thin crust frozen pizza, I can eat the entire thing in one sitting. But CPK thin crust isn't much at all, and even when on sale it's still a bit costly for what it is.
A large size Pizza Hut pan crust (assuming Meat Lover's), usually about 3/8's in one sitting, sometimes a little more. Depends on what else I eat along with it.
Eventually, I would like to be able to eat an entire large size Pizza Hut pizza in one sitting so a large will become my personal size. That way, additional pizzas will be needed when others are around and hungry.
