How Many Pizzas for 40 People
Order 15 large pizzas for 40 people. Forty people is a big party: a milestone birthday, a graduation, or an open house where pizza is the main food.
Count 3 slices per adult when pizza is the meal, 2 slices for each child under 10, and 4 slices for a big appetite. A filling side such as a large salad, wings, or bread is 2 slices per adult. A large pizza is 8 slices. 40 adults need 120 slices. 15 large pizzas are 120 slices, the same number counted.

What changes the count
- Count 2 slices for each child under 10. 12 children and 28 adults need 108 slices: 14 large pizzas.
- Count 4 slices for each big appetite. 8 big appetites and 32 other adults need 128 slices: 16 large pizzas.
- With a filling side such as a large salad, wings, or bread, plan 2 slices per adult. 40 people need 80 slices: 10 large pizzas.
| Situation | Slices | Large pizzas |
|---|---|---|
| 40 adults, pizza is the meal | 120 | 15 |
| 12 children and 28 adults | 108 | 14 |
| 8 big appetites and 32 other adults | 128 | 16 |
| Filling side with the pizza | 80 | 10 |
There are no spare slices at 15 pizzas, so add one more if several guests are big eaters or you want leftovers.
How many pizzas for 40 people by appetite and size
| Appetite | Slices each | Slices | Large pizzas | Medium pizzas |
|---|---|---|---|---|
| Light eaters, or a filling side | 2 | 80 | 10 | 14 |
| Average adults | 3 | 120 | 15 | 20 |
| Hungry eaters | 4 | 160 | 20 | 27 |
Large pizzas are cut into 8 slices. A medium pizza cut into 8 smaller slices covers about 6 large slices, so 120 slices for 40 people is 20 medium pizzas instead of 15 large pizzas. Every count is rounded up to a whole pizza.
Pizza for 40 people with children
| Guests | Slices | Large pizzas |

| 20 children and 20 adults | 100 | 13 |
| 30 children and 10 adults | 90 | 12 |

Pizza for 40: a big party
Forty people at three slices is 120 slices, and 15 large pizzas give exactly 120. The count lands on a whole number of pizzas, so there is no margin at all. For a crowd of average adults that is enough, but this is the size where one extra pizza is sensible insurance.
A big party is rarely all adults with average appetites. A graduation brings teenagers who eat like big appetites; a family party brings children. Use the tables above: 8 big appetites among the guests already push the order to 16, while 12 children bring it down to 14.
At this size the oven is the limit, not the order. 15 pizzas or more can be more than one shop bakes in a single batch. Split the order across two pickups or two shops, and plan for the first batch to be eaten while the second is on its way.
Ordering tips for 40 people
- Place the order at least a day ahead and confirm the delivery time on the morning of the party.
- Set up two serving tables so 15 boxes do not stack up in one place.
- Plan 4 plain cheese pizzas and label the vegetarian boxes.
