9 people, every pizza size
The count changes a lot with the size you order. A small pizza has less than half the area of an extra large one.
| Pizza size | Light eaters | Average | Very hungry |
|---|---|---|---|
| 10-inch small (6 slices) | 5 | 7 | 9 |
| 12-inch medium (8 slices) | 4 | 5 | 7 |
| 14-inch large (8 slices) | 3 | 4 | 5 |
| 16-inch extra large (8 slices) | 2 | 3 | 4 |
| 18-inch extra large (8 slices) | 2 | 3 | 3 |
| Guests | Pizza only | With sides or dessert |
|---|---|---|
| All adults | 4 | 3 |
| Half adults, half kids | 3 | 3 |
| All kids | 3 | 2 |
The math for 9 people
An average adult eats 3 slices of a large pizza. For 9 people that is 9 × 3 = 27 slices. A large pizza has 8 slices, so 27 ÷ 8 = 3.375, which rounds up to 4 pizzas. You will have about 5 slices to spare.
Light eaters average 2 slices, which brings the order down to 3. A hungry group at 4 slices each needs 5.
Ordering for a group of 9
A group of 9 is the classic pizza party: a birthday, a team dinner, a game night. Stick to large or extra large pizzas. You get more pizza for the money and fewer boxes to stack.
For toppings, make about a third of the order cheese and a third pepperoni, then split the rest between a vegetable pizza and one or two favorites. Ask about allergies, and make sure at least one pizza works for vegetarians.
Between two numbers? Round up. Cold pizza keeps for three to four days in the fridge, and running out is the only real way to get a pizza party wrong.
