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 10
24 grown-ups at 3 slices each need 72 slices. We add 10% so nobody’s left eyeing the last one, which makes 80. A large pizza has 8 slices, which is what Pizza Hut and Papa John’s cut theirs into, so 80 ÷ 8 = 10, exactly 10 pizzas with no rounding.
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.
Pizzas for 24 people by size
| Size | Slices in one | Pizzas for 24 | Slices in all |
|---|---|---|---|
| small | 6 | 14 | 84 |
| medium | 8 | 10 | 80 |
| large | 8 | 10 | 80 |
| extra-large | 12 | 7 | 84 |
The same 80 slices, divided by what each size holds and rounded up. Pick a size in the calculator above and the answer follows.
24 people, if some of them are kids
| Who’s coming | Grown-ups | Kids | Large pizzas |
|---|---|---|---|
| All grown-ups | 24 | 0 | 10 |
| A quarter kids | 18 | 6 | 10 |
| Half kids | 12 | 12 | 9 |
| Three-quarters kids | 6 | 18 | 8 |
Kids under 12 count 2 slices each, grown-ups 3. 24 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 24 grown-ups down to 8 large pizzas. Tick “Also serving wings, salad or other food” above to see it.
What 10 pizzas might cost, at example prices
| If a large cost (example) | 10 pizzas | For each of 24 |
|---|---|---|
| $12 | $120.00 | $5.00 |
| $16 | $160.00 | $6.67 |
| $20 | $200.00 | $8.33 |
| $24 | $240.00 | $10.00 |
Example prices only, to show the sum; a large costs whatever your pizzeria charges, before tax, delivery and tip. Switch the calculator to Office lunch and type in your price for the real total.
Ordering for a night shift, a scout pack or a backyard birthday
For a night shift, check when your pizzeria’s kitchen closes before you plan anything: a crew that eats in the small hours needs the order placed while the store’s still open. Order for the start of the break, not the end, so the last person on break isn’t eating cold pizza.
A scout pack is kids plus leaders, so put the scouts in the Kids box above and the leaders in Grown-ups. For a backyard birthday, set the pizza table where the kids won’t run through it, with a bin right beside it, because paper plates in a backyard travel.
