Planning a party can be a delightful experience, filled with anticipation and excitement. One crucial aspect of any gathering is the food, and when it comes to pleasing a diverse group of people, pizza often emerges as the go-to choice. In this article, we embark on a journey of ordering pizzas for 20 people. Join us as we explore the fun, challenges, and ultimately the satisfaction of arranging the perfect pizza feast.

How Many Pizzas to Order for 20 People?

Pizza is a popular food choice for parties and gatherings of all sizes. It’s easy to order, it’s delicious, and it can be enjoyed by people of all ages. But how many pizzas do you need to order for 20 people?

The answer to this question depends on a few factors, including the size of the pizzas, the appetites of your guests, and whether or not you’re serving other food.

Here are a few general guidelines to help you determine how many pizzas to order for 20 people:

Size of the pizzas for 20 people

If you’re ordering large pizzas, you’ll need fewer pizzas than if you’re ordering smaller pizzas. A large pizza typically has 8 slices, while a medium pizza typically has 6 slices.

The appetite of your guests

If your guests have big appetites, you’ll need to order more pizzas than if they have smaller appetites.

Other food being served

If you’re serving other food, such as appetizers or desserts, you can order fewer pizzas.

As a general rule of thumb, you should order 1 pizza per 4 people if you’re serving large pizzas. If you’re serving medium pizzas, you should order 1 pizza per 3 people.

So, if you’re hosting a party for 20 people and you’re serving large pizzas, you should order 5 pizzas. If you’re serving medium pizzas, you should order 6 pizzas.

Of course, these are just general guidelines. You may need to adjust the number of pizzas you order depending on the specific circumstances of your party.

Additional Tips

In addition to the tips mentioned above, here are a few additional tips for ordering pizza for a party:

  • Consider the dietary restrictions of your guests. If you have guests with dietary restrictions, such as gluten intolerance or lactose intolerance, be sure to order pizzas that are suitable for their needs.
  • If you’re ordering pizza for a children’s party, consider ordering pizzas with kid-friendly toppings, such as cheese, pepperoni, and sausage.
  • If you’re hosting a formal event, you may want to consider ordering gourmet pizzas. Gourmet pizzas are made with high-quality ingredients and are often more expensive than regular pizzas.
  • If you’re on a budget, you may want to consider ordering frozen pizzas. Frozen pizzas are a good option for parties where you don’t need to worry about the pizzas looking perfect.

The Importance of Knowing How Many Pizzas to Order

Ordering too little pizza can cause frustration and dissatisfaction among your guests while ordering too much can be a waste of money and food. Knowing how many pizzas to order ensures all your guests have enough to eat without any excess.

The Challenge of Feeding Large Groups   

Feeding large groups involves meticulous planning, especially when it comes to pizza. Understanding your guests’ appetites and preferences is crucial, and so is determining the right serving size and pizza size.

Factors to Consider When Calculating Pizza Quantity

When calculating pizza quantity, several factors come into play. These include:

Basic Calculation: Serving Size and Pizza Size

Determining the Standard Serving Size To determine the standard serving size, assume each guest will consume 2-3 slices. However, this could vary depending on appetite and age.

Pizza Sizes and Cuts per Pie Pizza sizes extend from little (10-12 inches), medium (12-14 inches), expansive (14-16 inches), to extra-large (16-18 inches)

Basic Equation for Pizza Calculation                                   

To calculate the number of pizzas needed, divide the total number of slices by the number of slices per pie. For example, if you need to serve 40 slices for 20 guests and each pizza has 8 slices, you’ll need 5 pizzas.

Variables Affecting Pizza Quantity

  • Appetite Variations Guests’ appetite varies, so consider ordering extra pizzas to accommodate any unexpected hungry guests.
  • Age Group Considerations Children eat smaller portions than adults, so if you’re catering for families, order a higher quantity of smaller pizzas.
  • Accompaniments and Alternative Options Consider ordering sides and alternative options like salads or chicken wings to supplement the pizzas.
  • Special Diets and Preferences Take into account any special dietary requirements like gluten intolerance, vegetarianism, or allergies when ordering.

How to Estimate the Exact Number of Pizzas

Here are some ways to help:

Surveying Guests

Send out a quick survey to your guests to gather information about their pizza preferences, appetites, and dietary requirements, helping you plan ahead.

Familiarize yourself with your guests’ consumption habits by observing their eating patterns at previous events.

Using Online Pizza Calculators

Online pizza calculators can help you estimate the number of pizzas needed based on the number of guests and preferred pizza size.

Pizza catering companies can assist in determining the appropriate pizza quantity based on their experience and expertise.
