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.Learn more about Food Measurements
