Pizza Calculator
Calculate how many pizzas to order for your party based on guests and appetite.
The Pizza Calculator takes the guesswork out of ordering pizza for a group. Enter the number of guests, slices per person, and slices per pizza to find out exactly how many pies you need.
The default assumes 3 slices per person (moderate appetite) and 8 slices per large pizza. Adjust for hungry guests (4-5 slices) or smaller pizzas (6 slices for medium). The calculator rounds up so you never run short.
Planning food for parties, office events, or family gatherings is stress-free with this simple tool. It even tells you how many leftover slices to expect.
Frequently Asked Questions
How many slices should I plan per person?
Adults typically eat 2-3 slices, teenagers 3-4, and children 1-2. For a mixed group, 3 slices per person is a safe average.
How many slices are in a large pizza?
Most large pizzas (14-16 inches) are cut into 8 slices. Medium pizzas (12 inches) usually have 6 slices.
Should I order extra?
Adding 1 extra pizza is a good idea for groups over 10 people, especially if there are varied appetites or you want leftovers.
