About this tool
Pizza Order Calculator tells you how many pizzas to order. Enter the number of guests, how hungry they are (light, normal or very hungry) and the pizza size, and it calculates total slices needed, pizzas to order and the rough cost.
A common rule of thumb is 2–3 slices per adult, a bit more for hungry teens and a bit less for small kids. The calculator rounds up — leftover pizza is never a problem.
Who it's for

Team lunches.
