Pizza Party Size Calculator

A common catering estimate is about 3 slices per adult for a regular meal, though this varies with what else is being served and how big the slices are cut.

At 8 slices per pizza and 3 slices per person, one large pizza feeds a little under 3 adults as a full meal, or more if it's served alongside other food.

Ordering a mix (like a couple of cheese, a pepperoni, and a veggie option) generally works well for groups of 8+ so there's something for different preferences, without changing the total pizza count from this calculator.
