Feeding the whole office?

Same crowd, different appetites
These follow the calculator above, so they change with the size and the headcount.
How we got to 29
70 grown-ups at 3 slices each need 210 slices. We add 10% so nobody’s left eyeing the last one, which makes 231. A large pizza has 8 slices, which is what Pizza Hut and Papa John’s cut theirs into, so 231 ÷ 8 = 28.88, and we round up to 29.
How to split 29 pizzas
We’d go 10 cheese, 10 pepperoni and 9 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.

| Half kids | 35 | 35 | 25 |

Ordering for a wedding after-party, a whole grade or a team fundraiser
A wedding after-party orders late, once the guests have danced off dinner, so call the pizzeria during the reception, not after, and check it’s still open when you want the delivery. Ask someone who isn’t the couple to meet the driver.
For a whole grade, serve in the cafeteria or the gym: spread the 29 boxes along a long table by topping and bring the classes through in turns. A team fundraiser runs on volunteers, so feed them first, before the doors open, and they’ll work the rest of the event in a better mood.
