Pizza Party Calculator: How Many Pizzas to Order?

Calculate exactly how many pizzas to order based on the number of guests and their appetite.

The 3/8 Rule for Pizza

A standard large pizza typically has 8 slices. The 'Golden Rule' of party planning suggests estimating 3 slices per adult and 2 slices per child. This usually ensures everyone gets enough to eat without excessive leftovers.

Ordering FAQs

What is the most popular topping?

Pepperoni is the most popular, followed closely by plain Cheese (which is safe for picky eaters) and Sausage.
