Same crowd, different appetites
These follow the calculator above, so they change with the size and the headcount.
How we got to 10
22 grown-ups at 3 slices each need 66 slices. We add 10% so nobody’s left eyeing the last one, which makes 73. A large pizza has 8 slices, which is what Pizza Hut and Papa John’s cut theirs into, so 73 ÷ 8 = 9.13, and we round up to 10.
How to split 10 pizzas
We’d go 4 cheese, 3 pepperoni and 3 veggie or specialty. Cheese is the safe bet for kids and picky eaters, and the veggie pizzas cover anyone who skips meat. If you know your crowd, move pizzas between the three; the total stays the same.

22 people, if some of them are kids
| Who’s coming | Grown-ups | Kids | Large pizzas |

| All grown-ups | 22 | 0 | 10 |
| A quarter kids | 16 | 6 | 9 |
| Half kids | 11 | 11 | 8 |
| Three-quarters kids | 5 | 17 | 7 |
Kids under 12 count 2 slices each, grown-ups 3. 22 kids on their own need 7.
Serving other food too?
Serving wings, salad or sides? We count 75% of the usual slices when there’s other food, which brings 22 grown-ups down to 7 large pizzas. Tick “Also serving wings, salad or other food” above to see it.

Ordering for a class with its teachers, a cast party or a two-family reunion
A cast party starts late and runs on adrenaline, so order before the curtain call and have the boxes waiting when the cast comes out. Actors who’ve just finished a show eat as if they skipped lunch, because they did.
At a two-family reunion each family knows what its own kids will eat, so let each one choose half the toppings: 5 pizzas each, if you split the 10 down the middle. Keep a pen by the boxes so whoever opens one can write the topping on the lid.
