Enter your guest count and how hungry the crowd is likely to be.
Most standard pizzas are cut into 8 slices. Catering guidance typically assumes about 3 slices per adult for a normal meal, more for a hungrier crowd (like teenagers) and fewer for a light snack alongside other food. This calculator multiplies guests by slices-per-person, then divides by 8 and rounds up to a whole pizza.
Source: Based on the common catering assumption of 3 slices per adult from an 8-slice pizza, adjusted by appetite level.
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.
