Planning a party? Find out exactly how many pizzas to order for your group. 🍕
People → pizzas to order
The classic rule of thumb is 3 slices per adult and about 2 per child, though hungry crowds, game days and teenagers can push that to 4–5. A standard large pizza has 8–10 slices, so a simple way to estimate is: multiply guests by slices-per-person, then divide by slices-per-pizza and round up.
This calculator does that math for you and even suggests ordering a spare for big groups so you never run short. Mixing sizes and a few different toppings keeps everyone happy — and cold pizza the next morning is never a bad outcome.
