Same crowd, different appetites
These follow the calculator above, so they change with the size and the headcount.
How we got to 15
35 grown-ups at 3 slices each need 105 slices. We add 10% so nobody’s left eyeing the last one, which makes 116. A large pizza has 8 slices, which is what Pizza Hut and Papa John’s cut theirs into, so 116 ÷ 8 = 14.5, and we round up to 15.
How to split 15 pizzas
We’d go 5 cheese, 5 pepperoni and 5 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.

35 people, if some of them are kids
| Who’s coming | Grown-ups | Kids | Large pizzas |

| All grown-ups | 35 | 0 | 15 |
| A quarter kids | 26 | 9 | 14 |
| Half kids | 17 | 18 | 12 |
| Three-quarters kids | 9 | 26 | 11 |
Kids under 12 count 2 slices each, grown-ups 3. 35 kids on their own need 10.
Serving other food too?
Serving wings, salad or sides? We count 75% of the usual slices when there’s other food, which brings 35 grown-ups down to 11 large pizzas. Tick “Also serving wings, salad or other food” above to see it.

Ordering for a church youth group, a team banquet or a whole office floor
At a team banquet, don’t let the pizza sit through the speeches: have it arrive after the awards, or put it out first and save the trophies for dessert. A church youth group of 35 spans a lot of ages, so count the younger kids in the Kids box above and the teens and leaders as grown-ups.
For a whole office floor, 15 boxes need a conference table, not the kitchen counter. Switch the calculator to Office lunch to add the vegetarians and gluten-free eaters and put in your price, so the cost per person is ready before anyone asks.
