5/5 - (2 votes)

Pizza sizes can be a bit confusing because they vary from one place to another. But generally, pizzas come in different sizes like small, medium, large, and extra-large. The size of a pizza is usually measured by its diameter, which is the length across its center.

Smaller pizzas are perfect for a few people, while larger ones are great for groups. Knowing the size helps you choose the right pizza for your hunger level and the number of people sharing it.

How Many Pizzas Should I Order?

To order the right number of pizzas, multiply the number of guests by 3 (average slices per person), and divide by 8 (slices in a large pizza). For example, for 20 guests: 20×3=6020×3=60 slices are needed. 60÷8=7.560÷8=7.5, so order 8 pizzas.

Quick slice guide:

  • Small (8-10″): 6 slices, serves 2-3.
  • Medium (12″): 8 slices, serves 3-4.
  • Large (14-18″): 8-12 slices, serves 3-7.

Use this formula: �×38=�X×83​=P (X = guests, P = pizzas to order).
