Budgeting Guides for Your Pizza Party
How much pizza do I really need?
The general "Pizza Rule" is 3 slices per adult and 2 slices per child. However, this can vary based on:
- Time of day: Lunch and dinner parties require more food than mid-afternoon snacks.
- Other food: If you're serving heavy appetizers or sides, you can reduce the pizza count by 20%.
- Party duration: For every hour past the 3-hour mark, guests tend to get hungry again.
Budgeting Tip: Wondering about the price? See our guide on how much pizza for 10 guests costs to plan your party budget effectively.
