Number of Guests multiplied by 3 ( avg. slices a person eats) then divide that by 8 (avg slices on a large pizza) = how many pizzas you should order. Example: 20 guests X 3 slices each = 60 slices of pizza. Divide 60 slices into 18 and you get 7.5, so you should order 8 pizzas.

Thus, for 100 attendees you would order 38 pies (100 x 3/8 = 37.5). If you arrive at a number with a decimal, round up to be on the safe side. This math is based on the average person eating three pieces of pizza, with the typical pie being cut into eight slices.

Here's your explanation: You might remember that the area A of a circle with radius z is given by A=π ⋅ z². A pizza is approximately the shape of a cylinder, so to get its volume, we have to multiply its area by its height. Thus the volume V of a pizza with height a is given by V=a⋅ A = pi ⋅ z ⋅ z ⋅ a!

Pizza Math

Take the radius (half the diameter) of the pizza—4 inches for a small, 6 inches for a medium—and then multiply the answer by 3.14. That means your 8-inch baby pizza has a surface area of a little over 50 square inches, while the 12-inch medium pizza has a surface area of 113 square inches.

15 People = 6 Pizzas. 20 People = 8 Pizzas. 30 People = 12 Pizzas. 50 People = 19 Pizzas.

Pizza is high in saturated fats due to cheese and processed meat toppings, which can increase your cholesterol levels as well as risk for heart disease. Eating three-four slices of pizza or more, on a regular basis, can have detrimental health consequences.

The number of pizzas you will need to satisfy 30 people depends on various factors such as pizza size, crust type, toppings, and the appetite of your guests.

The Pizza Formula

Thus, the number of pizzas p you should order is equal to 3 times the number of guests a, divided by 8. This works for any style of pizza. Even the experts at Green Lantern Pizza suggest a ratio of 3/8 is ideal for ordering so that even the last one to arrive isn't left sliceless!

For example, if you need to know how much pizza to order for 16 people, complete 16 x (3/8). You may get a fraction as the final result when completing the math. If this is the case, it's always best to round the final number up. For example, if the result is 7.88, round up to get 8 pies.

All estimates are based on a 12″ medium pizza. 5–10/11 consider about four pizzas. This is enough for two slices per person and a few for the adults.

You want to order enough food that no one goes hungry, without having too many leftovers to take home. A simple formula for figuring out how many pizzas to order is planning on about three slices for each adult attending. If the party guests are primarily kids, you can plan for two slices each.

To prevent drastically under or overestimating how much pizza to order for a party, it's typically best to follow the 3/8 rule: Simply multiply the number of guests by 3/8.

In most cases, an individual will eat approximately three slices. With that information in mind, do some basic math. If you have five hungry mouths to feed, then that means you'll need about fifteen slices of pizza, give or take. You can get that amount with two boxes of pizza, since they'll be sliced up in eighths.
