How Many Pizzas for 25 People?

The standard party rule is 3 slices per adult and 2 per child, with 8 slices in a large pizza. Round up — cold pizza disappears the next morning; a shortage is remembered forever.

Order 60–70% of pizzas as crowd-pleasers (cheese and pepperoni) and the rest as specialty pies.

Adjusting for your crowd: kids eat about two-thirds of adult portions; knock 25% off any single item when several mains share the table; add 25% for teenagers and big appetites. When in doubt, round up on the cheap items (buns, chips, ice) and stay exact on the expensive ones.
