80 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) | 40 | 59 | 79 |
| 12-inch medium (8 slices) | 28 | 41 | 55 |
| 14-inch large (8 slices) | 20 | 30 | 40 |
| 16-inch extra large (8 slices) | 16 | 23 | 31 |
| 18-inch extra large (8 slices) | 13 | 19 | 25 |
| Guests | Pizza only | With sides or dessert |
|---|---|---|
| All adults | 30 | 23 |
| Half adults, half kids | 25 | 19 |
| All kids | 20 | 15 |
The math for 80 people
An average adult eats 3 slices of a large pizza. For 80 people that is 80 × 3 = 240 slices. A large pizza has 8 slices, so 240 ÷ 8 = 30, which rounds up to 30 pizzas. That comes out exactly, with nothing to spare, so add one more if your guests are big eaters.
Light eaters average 2 slices, which brings the order down to 20. A hungry group at 4 slices each needs 40.
Ordering for an event of 80
Feeding 80 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.
