23 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.

|---|---|---|---|
| 10-inch small (6 slices) | 12 | 17 | 23 |
| 12-inch medium (8 slices) | 8 | 12 | 16 |
| 14-inch large (8 slices) | 6 | 9 | 12 |
| 16-inch extra large (8 slices) | 5 | 7 | 9 |
| 18-inch extra large (8 slices) | 4 | 6 | 7 |
| Guests | Pizza only | With sides or dessert |
|---|---|---|
| All adults | 9 | 7 |
| Half adults, half kids | 8 | 6 |
| All kids | 6 | 5 |
The math for 23 people
An average adult eats 3 slices of a large pizza. For 23 people that is 23 × 3 = 69 slices. A large pizza has 8 slices, so 69 ÷ 8 = 8.625, which rounds up to 9 pizzas. You will have about 3 slices to spare.
Light eaters average 2 slices, which brings the order down to 6. A hungry group at 4 slices each needs 12.
Ordering for a crowd of 23
At 23 people, call the shop a day ahead. An order this size takes real oven time, and most pizzerias will give you a pickup or delivery window if you ask early.
Have the pizzas arrive in two waves, 20 to 30 minutes apart, so the second half is still hot. Keep toppings simple: cheese, pepperoni, one vegetable and one meat. Ask whether the shop has a bulk or party price.
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.
