| 10-inch small (6 slices) | 45 | 67 | 89 |
| 12-inch medium (8 slices) | 31 | 46 | 62 |
| 14-inch large (8 slices) | 23 | 34 | 45 |
| 16-inch extra large (8 slices) | 18 | 26 | 35 |
| 18-inch extra large (8 slices) | 14 | 21 | 28 |
| Guests | Pizza only | With sides or dessert |
|---|---|---|
| All adults | 34 | 26 |

The math for 90 people
An average adult eats 3 slices of a large pizza. For 90 people that is 90 × 3 = 270 slices. A large pizza has 8 slices, so 270 ÷ 8 = 33.75, which rounds up to 34 pizzas. You will have about 2 slices to spare.
Light eaters average 2 slices, which brings the order down to 23. A hungry group at 4 slices each needs 45.
Ordering for an event of 90
Feeding 90 people is a catering order. Speak to the shop several days ahead, ask for a quote in writing, and confirm how many slices they cut each pizza into, because that changes how far the order goes.
Consider 18-inch or party-size pizzas to cut the number of boxes, stagger delivery into three waves, and set out the cheese pizzas first. At this size, sides and salad are cheap insurance against running short.
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.
