What Is Pizza Party?
Knowing how many pizzas to order prevents running out (awkward) or over-ordering (wasteful). Most adults eat 2-4 slices.
Formula
Pizzas = ⌈(Guests × Slices Per Person) / Slices Per Pizza⌉Example
12 guests eating 3 slices each = 36 slices ÷ 8 slices/pizza = 5 pizzas.
Frequently Asked Questions
What size pizza should I order?
Large (14") pizzas are the best value. A large is roughly 2× the area of a small (10") — it's not just 40% bigger!
Should I add extra?
Order 1-2 extra pizzas for a buffer, especially with teenagers or a crowd that's been drinking.
