How much pizza per person
Plan 3 slices per adult, 4 for big eaters and 2 per child, from a large pizza cut into 8 slices. That is about 3/8 of a large pizza per adult.
When a filling side is on the table (wings, salad, breadsticks), drop adults to 2 slices. These are the same slice counts used by the pizza calculator on OrderFast.
| Who / occasion | Per person | 10 people | 20 people | 30 people | 50 people |
|---|---|---|---|---|---|
| Adults | 3 slices | 30 | 60 | 90 | 150 |
| Big eaters | 4 slices | 40 | 80 | 120 | 200 |
| Kids | 2 slices | 20 | 40 | 60 | 100 |
| Adults, with a filling side | 2 slices | 20 | 40 | 60 | 100 |
| Large pizzas (all adults) | 3 slices each | 4 | 8 | 12 | 19 |
| Large pizzas, with a side | 2 slices each | 3 | 5 | 8 | 13 |
Tips
- Pizzas = total slices รท 8, rounded up.
- Medium pizzas are usually cut into 6 or 8 smaller slices; count 2 medium slices as about 1.5 large ones.
- Order one plain cheese pizza for every three or four pizzas so picky eaters and kids are covered.

These counts are rules of thumb. Portion sizes vary by restaurant and caterer, so ask them if their pieces or trays run small or large.
