45 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) | 23 | 34 | 45 |
| 12-inch medium (8 slices) | 16 | 23 | 31 |
| 14-inch large (8 slices) | 12 | 17 | 23 |
| 16-inch extra large (8 slices) | 9 | 13 | 18 |
| 18-inch extra large (8 slices) | 7 | 11 | 14 |
| Guests | Pizza only | With sides or dessert |
|---|---|---|
| All adults | 17 | 13 |
| Half adults, half kids | 14 | 11 |
| All kids | 12 | 9 |
The math for 45 people
An average adult eats 3 slices of a large pizza. For 45 people that is 45 × 3 = 135 slices. A large pizza has 8 slices, so 135 ÷ 8 = 16.875, which rounds up to 17 pizzas. You will have about 1 slice to spare.
Light eaters average 2 slices, which brings the order down to 12. A hungry group at 4 slices each needs 23.
Ordering for a crowd of 45
At 45 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.
