Pizza Party Calculator
Work out how many pizzas to order for a group, by appetite and pizza size.
Feeding the group
Ordering pizza for a crowd is a guessing game that usually ends in too much or too little. This works out how many pizzas to order from the number of people and how hungry they are, so everyone is fed without a fridge full of leftovers or a run to order more.
Enter the headcount and appetite to see how many pizzas to order.
Slices, sizes and hunger
The maths comes down to slices: a typical adult eats a few slices, children fewer, and a big-appetite crowd more, against how many slices each pizza size yields. The common rule of thumb is around three slices per adult, adjusted for the occasion — people eat more at a party than a working lunch. Ordering fewer large pizzas is usually better value and easier than many small ones, and it is wise to round up slightly.
