How many pizzas per person?
As a practical guide for a pizza night, the source cited here gives around 1.2 pizzas per adult and about 0.7 per child, based on pizzas of roughly 30–32 cm. Rounding is always to whole pizzas — and it happens once on the total, not per guest.
Pizzas for 10 to 100 people
| People | Pizzas needed (whole) |
|---|---|
| 10 | 12 |
| 20 | 24 |
| 30 | 36 |
| 50 | 60 |
| 100 | 120 |
Figures for adult guests. 20 adults works out to 24 pizzas — which becomes 24 whole pizzas, because you cannot bake a partial pizza.

The basis is a simple margherita: dough, tomato sauce and mozzarella. Dieselbe Quelle nennt für Kinder ca. 0,7 Pizzen pro Kind sowie je Pizza: 250–270 g Teig, ca. 70 g Tomatensauce, 80–100 g Mozzarella, maximal 50–80 g weiterer Belag.
Ingredient amounts are converted into packs only after being summed across all pizzas — not per individual pizza. Otherwise every pizza would carry its own rounding.
