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 6
13 grown-ups at 3 slices each need 39 slices. We add 10% so nobody’s left eyeing the last one, which makes 43. A large pizza has 8 slices, which is what Pizza Hut and Papa John’s cut theirs into, so 43 ÷ 8 = 5.38, and we round up to 6.
How to split 6 pizzas
We’d go 2 cheese, 2 pepperoni and 2 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 13 people by size
| Size | Slices in one | Pizzas for 13 | Slices in all |
|---|---|---|---|
| small | 6 | 8 | 48 |
| medium | 8 | 6 | 48 |
| large | 8 | 6 | 48 |
| extra-large | 12 | 4 | 48 |
The same 43 slices, divided by what each size holds and rounded up. Pick a size in the calculator above and the answer follows.
13 people, if some of them are kids
| Who’s coming | Grown-ups | Kids | Large pizzas |
|---|---|---|---|
| All grown-ups | 13 | 0 | 6 |
| A quarter kids | 10 | 3 | 5 |
| Half kids | 6 | 7 | 5 |
| Three-quarters kids | 3 | 10 | 4 |
Kids under 12 count 2 slices each, grown-ups 3. 13 kids on their own need 4.
Serving other food too?
Serving wings, salad or sides? We count 75% of the usual slices when there’s other food, which brings 13 grown-ups down to 5 large pizzas. Tick “Also serving wings, salad or other food” above to see it.

Ordering for a scout meeting, a band practice or a small class
A scout meeting or a small class usually means kids, so count them in the Kids box above: 13 kids on their own need 4 large pizzas, not 6. Ask the leaders about allergies before you order, not when the boxes open.
A band practice eats on the break, so set the delivery time for the break, and keep the boxes well away from the instruments and the sheet music.
Questions people ask
How many large pizzas do I need for 13 people?
6 large pizzas for 13 grown-ups with normal appetites. That’s 48 slices, about 3 each plus spares. If they’re nibblers, 4 will do; if they’re starving, get 8.
Can I order small pizzas for 13 people instead?
Yes, just more of them: we count 6 slices in a small, so the same 43 slices take 8 smalls instead of 6 larges. That’s more boxes, but more toppings to go around, and a small is the easy way to give a picky eater a pizza of their own. Our pizza sizes guide has how big each size is.
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.
How many pizzas for 13 kids?
4 large pizzas for 13 kids under 12, at 2 slices each plus a little extra. Add the grown-ups in the calculator if they’re eating too.
How much does pizza for 13 people cost?
