2 : Understanding Pizza sizes:

                        Most pizza places offer common three sizes: small, medium, and large.

2.1 : Small Pizza Size

                        The Pizzass in small sizes are typically 10–12 inches in diameter. A small pizza is enough to serve 1-2 depending upon hunger level. A small pizza is recommended for a single person or in a small gathering.

2.2 : Medium Pizza Size

                        The Medium pizza is mostly 12–14 inches in diameter. It is fulfilling for 2–3 people. Medium pizza is the best choice for a small family with a moderate appetite.

2.3 : Large Pizza Size

                        The Large pizzas are typically 16–18 in diameter. It can serve 3–4 people. This is ideal for a large group or a fulfilling family gathering.

4 : Introduction to the “Pizza Formula”

                        Although we have developed calculator for you where you can just select your requirements and you can get the results but still if you want to know how things are being calculated, here is the breakdown:

p = (Total Guests * Average Slices per Person) / Slices per Pizza

For example, if you are having 10 number of guests with average appetite, you estimate that 2 slices per person will be enough with the detail of ordering large pizza having 8 slices. Then here will be the math

p = (10 guests * 2 slices/guest) / 8 slices/pizza = 2.5 pizzas

As you can’t order half pizza anywhere thus we can round off this digit and it comes as number 3. So you will need 3 large pizzas with 8 slice cut down to serve 10 guests with details of 2 slices per person.

Bonus Tip: The Leftover Factor

You may send leftover pizza to your neighbors for keeping a good relationship or you may refrigerate and consume it on your next meal. Thanks me later.

5 : Pro Tips for Ordering Pizza for a Group

                            Before we go into the calculation of pizza math, let’s discuss some variables that will need you to consider the requirements.

5.1 : Number of guests/family members

                        This is the first step to determine the need for pizza. You must have the exact number to know how many pizza is needed.

5.2 : Estimate the appetite

                        You must estimate the hunger level of the audience to serve. Whether you are ordering pizza in a high tea among other dishes to be served or you are going to serve pizza as a main dish. The next is to know the timings of pizza, whether it is going to be served at dinner or lunch or at snack time.

5.3 : Crust consideration 

                        Conventional crust or thin crust as the conventional crust has a thicker crust and you may need less bite.

5.4 : Pizza Sizes with slice ratio 

                        You must also consider the pizza sizes and their offered slices as it effects a lot in gathered serving. A medium standard 12-inch pizza mostly offers 8 slices while a large pizza offers 10 slices.
