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 33
80 grown-ups at 3 slices each need 240 slices. We add 10% so nobody’s left eyeing the last one, which makes 264. A large pizza has 8 slices, which is what Pizza Hut and Papa John’s cut theirs into, so 264 ÷ 8 = 33, exactly 33 pizzas with no rounding.
How to split 33 pizzas
We’d go 11 cheese, 11 pepperoni and 11 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.

80 people, if some of them are kids
| Who’s coming | Grown-ups | Kids | Large pizzas |
|---|---|---|---|
| All grown-ups | 80 | 0 | 33 |
| A quarter kids | 60 | 20 | 31 |
| Half kids | 40 | 40 | 28 |
| Three-quarters kids | 20 | 60 | 25 |
Kids under 12 count 2 slices each, grown-ups 3. 80 kids on their own need 22.
Serving other food too?
Serving wings, salad or sides? We count 75% of the usual slices when there’s other food, which brings 80 grown-ups down to 25 large pizzas. Tick “Also serving wings, salad or other food” above to see it.

Ordering for an open house, a company picnic or a charity auction
At an open house people graze rather than sit down to a meal, which is when the Nibblers setting and the other-food box earn their keep; the question below has the count. Put the boxes near the door people leave by, not the one they come in, so the line doesn’t block the entrance.
For a company picnic, the 33 boxes need shade, a table and something heavy on the napkins. At a charity auction, keep the pizza out of the auction room: greasy fingers and bid sheets don’t mix.
