Feeding the whole office?
Past 20 people, compare catering on cost per head before you order a tower of pizza boxes. Someone else brings the plates.
Same crowd, different appetites
These follow the calculator above, so they change with the size and the headcount.
How we got to 4
9 grown-ups at 3 slices each need 27 slices. We add 10% so nobody’s left eyeing the last one, which makes 30. A large pizza has 8 slices, which is what Pizza Hut and Papa John’s cut theirs into, so 30 ÷ 8 = 3.75, and we round up to 4.
How to split 4 pizzas
We’d go 2 cheese, 1 pepperoni and 1 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.
Pizzas for 9 people by size
| Size | Slices in one | Pizzas for 9 | Slices in all |
|---|---|---|---|
| small | 6 | 5 | 30 |
| medium | 8 | 4 | 32 |
| large | 8 | 4 | 32 |
| extra-large | 12 | 3 | 36 |
The same 30 slices, divided by what each size holds and rounded up. Pick a size in the calculator above and the answer follows.
9 people, if some of them are kids
| Who’s coming | Grown-ups | Kids | Large pizzas |
|---|---|---|---|
| All grown-ups | 9 | 0 | 4 |
| A quarter kids | 7 | 2 | 4 |
| Half kids | 4 | 5 | 4 |
| Three-quarters kids | 2 | 7 | 3 |
Kids under 12 count 2 slices each, grown-ups 3. 9 kids on their own need 3.
Serving other food too?
Serving wings, salad or sides? We count 75% of the usual slices when there’s other food, which brings 9 grown-ups down to 3 large pizzas. Tick “Also serving wings, salad or other food” above to see it.

Ordering for a softball team, a fantasy football draft or a craft night
After a softball game, call the order in during the last inning so the pizza and the team get to the same place at the same time; a team that’s waiting for pizza eats the snack bar first.
A fantasy draft runs longer than anyone plans and nobody wants to miss a pick, so put the 4 boxes where people can reach them from their seats. At a craft night, keep the pizza on its own table, away from the glue and the yarn; grease and craft supplies don’t mix.
Questions people ask
How many large pizzas do I need for 9 people?
4 large pizzas for 9 grown-ups with normal appetites. That’s 32 slices, about 3 each plus spares. If they’re nibblers, 3 will do; if they’re starving, get 5.
What toppings should I get on 4 pizzas for 9 people?
We’d go 2 cheese, 1 pepperoni and 1 veggie. 4 doesn’t split evenly three ways, so the odd one goes to cheese, the pizza almost everybody eats. If 2 of the 9 skip meat, the veggie pizza is 8 slices, enough for them with some to share; if more do, switch a cheese to veggie and the total stays 4.
How many slices of pizza per person?
Plan on 3 slices for a grown-up, 2 for a light eater or 2 for a kid, and 4 for a hungry crowd. Those are the numbers our calculator uses, before the 10% extra.

3 large pizzas for 9 kids under 12, at 2 slices each plus a little extra. Add the grown-ups in the calculator if they’re eating too.
