How many slices in a pizza pie?

The average large pizza is cut into eight slices. This number of slices is also standard on most deep-dish pizza pies.

Most large pizzas measure between 14 and 16 inches in diameter, and they are available with a variety of crusts and toppings. New York-style pizzas are slightly larger at 18 inches in diameter.

When serving crowds, it advised to offer 3 to 4 slices for men, 2.5 to 3 for women and 1 to 2.5 for children. If side dishes are also being served, the portions per person may be smaller. Select pizza restaurants can also cut pizza in smaller or larger slices, if needed.
