How many pizzas for 15 people by appetite and size
| Appetite | Slices each | Slices | Large pizzas | Medium pizzas |
|---|---|---|---|---|
| Light eaters, or a filling side | 2 | 30 | 4 | 5 |
| Average adults | 3 | 45 | 6 | 8 |
| Hungry eaters | 4 | 60 | 8 | 10 |
Large pizzas are cut into 8 slices. A medium pizza cut into 8 smaller slices covers about 6 large slices, so 45 slices for 15 people is 8 medium pizzas instead of 6 large pizzas. Every count is rounded up to a whole pizza.

Pizza for 15: a birthday party
Fifteen is a typical birthday party, and the guest list is rarely all adults. If everyone is an adult, 45 slices rounds up to 6 large pizzas. For a children's party, count each child under 10 at two slices: 9 children and 6 adults need 36 slices, which is 5 large pizzas.
Birthday food is rarely only pizza. Crisps, a fruit plate and the cake all take room, and children often fill up on snacks before the pizza arrives. If the table already has a substantial side, use the light row: 4 pizzas for fifteen people at two slices each.
Children are picky about toppings. Make at least 2 of the pizzas plain cheese and keep the adventurous toppings for the adults. A half-and-half pizza helps when two or three guests want something specific without committing a whole pizza to it.
Ordering tips for 15 people
- Confirm the final headcount a day ahead, including parents who stay. Parents who stay to eat count as adults.
- Ask for the children's pizzas cut into smaller squares if the shop offers it; small pieces mean fewer half-eaten slices.
- Keep one pizza in a warm oven for latecomers instead of opening every box at once.
