How Many Pizza Do I Need

The first rule of planning for a feast is to estimate the number of guests. Knowing how many people you expect to sit around your table helps you know how much to serve. But, kids and adults will not eat the same amount of pizza.

How much pizza can children eat?

American adults aren’t the only ones with an excellent appetite for pizza- their children are, too! Kids can eat as much pizza as they see.

Kids may want to eat too many slices, but you’ll have to regulate that. The good thing is that the number of slices is more important to a kid than its size. So, insist that the medium pizza be sliced ten times. The slices will be a little smaller, and they will cover more kids.

If you’re paying attention to your kid’s weight as well, you may want to stick to two or fewer slices per sitting. Nutritionists recommend that you pair the pizza with salads and veggies for the meal.

However, your kid won’t suffer any nutritional issues by eating the occasional pizza.

How many pizza slices will adults eat?

An adult will not have a problem eating a few more slices of pizza than a kid. The average adult can take 2-3 slices depending on his or her appetite.

How hungry are the guests?

Never underestimate the appetite of the people you’ve invited. If your Auntie Jemimah would eat half a pizza and still yawn with hunger, you have to plan enough for her.

Of course, determining your guests’ appetite can be a rocky path. But, you can check whether they have eaten anything beforehand.

If you’re serving pizza to a hungry table of guests, you can order three slices for each adult and two for kids. If you already know that your visitors have a known appetite for pizza, add one or two slices for every person, just to be on the safe side.

In short, multiply the number of adult visitors by three and kids by two. Then, buy the pizza that achieves the sum of the two results. Now, divide the number you get by the number of slices in each pizza you order. This formula should help you get the best pizza sizes or the number of pizzas to order for your event.

However, when you’re estimating the appetite of your guests, you will have to be ready to keep up with the leftovers. Solve this by encouraging them to carry a few home.

Is pizza the only thing on your plate?

When ordering your pizza, consider the nature of your event. Some events may require you to order more pies. For instance, you could go for a pizza-only party or include more snacks on the menu.
