Ordering for a crowd? Enter your headcount and how hungry everyone is, and we'll tell you exactly how many pizzas to get — no cold-slice math, no running short.

|---|
| 5 people | 2 pizzas | 3 slices |

How it works
The math is slice-based: an average adult eats about 3 slices, a lighter eater or child about 2, and a big appetite around 4. The tool totals the slices your guests will eat, divides by the number in your chosen pizza size, and rounds up to whole pizzas. Ordering slightly extra is smart — leftover pizza keeps, running short doesn't.
Frequently asked
How many slices does one pizza have?
It depends on size — a small (10") is usually 6 slices, medium (12") 8, large (14") 10, and extra-large (16") 12. The calculator uses whichever size you pick.
How many slices does the average person eat?
Plan on about 3 slices for an average adult, 2 for a lighter eater or a child, and 4 for a big appetite. We adjust by the hunger level you choose.
Should I order extra?
A little. It's better to have leftovers than to run out — we round up to whole pizzas, and cold pizza is never wasted.
How many pizzas for 50 people?
At about 3 slices each and 10 slices per large pizza, roughly 15 large pizzas — adjust for appetite and how many sides you're serving.
How do I keep pizza warm for a crowd?
Hold it in a 200 °F oven or insulated bags, stacked loosely — don't seal it up, which steams the crust soggy.
