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 11
25 grown-ups at 3 slices each need 75 slices. We add 10% so nobody’s left eyeing the last one, which makes 83. A large pizza has 8 slices, so 83 ÷ 8 = 10.38, and we round up to 11.
Ordering extra-large instead? At 12 slices a pizza, 25 people need 7 extra-large pizzas.
How to split 11 pizzas
We’d go 4 cheese, 4 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.
With kids, or other food on the table
We count kids under 12 at 2 slices. If half the group is kids (13 grown-ups and 12 kids), 9 large pizzas will do, and 25 kids on their own need 7.
Serving wings, salad or sides too? We count 75% of the usual slices when there’s other food, which brings 25 grown-ups down to 8 large pizzas. Tick “Also serving wings, salad or other food” above to see it.
Ordering for a classroom, a youth sports team or a department lunch
11 pizzas is an easy order for one store. Order well before you want to eat, especially on a Friday or Saturday night, and ask for plates and napkins if you don’t have them.
