What Are Pizzas?

Pizzas are a popular food item loved by people of all ages around the world. They typically consist of a crust made from yeast-risen dough that is flattened and topped with tomato sauce, cheese, and a variety of other toppings. The toppings can include vegetables, meats, seafood, herbs, and spices, depending on personal preferences. Pizzas are versatile and can be customized to suit various tastes, making them an ideal food choice for parties and gatherings. They can be baked in a traditional oven, on a grill, or even on a stovetop in a skillet.

The ⅜ Rule

The ⅜ rule is a helpful guideline often used for estimating pizza consumption. According to this rule, each person tends to consume around 3/8th of a pizza. This rule takes into account the average hunger level of individuals and factors in other food options available at the party. By applying the ⅜ rule, you can calculate how many pizzas you should order to satisfy your guests without overdoing it.

When planning a pizza party, it’s important to strike a balance between providing enough food for everyone and minimizing waste. The ⅜ rule offers a practical solution to determine the appropriate quantity of pizzas required based on the average portion size per person.

To apply the ⅜ rule, follow these steps:

  1. Calculate the number of guests attending your party.
  2. Multiply the total guest count by 3/8th to determine the number of whole pizzas needed.
  3. If you end up with a fractional value, round up to the nearest whole pizza to ensure you have enough.

For example, if you are hosting a pizza party for 20 people:

  1. Number of guests: 20
  2. Number of whole pizzas needed: 20 x 3/8 = 7.5 pizzas
  3. Rounded up to the nearest whole pizza: 8 pizzas

By using the ⅜ rule, you can estimate the quantity of pizzas required for your party, taking into account the average appetite of your guests. However, it’s important to remember that individual preferences and appetite levels may vary, so it’s always a good idea to have some extra pizzas on hand to ensure everyone is well-fed and satisfied.

Factors Affecting Pizza Needs

Factors Affecting Pizza Needs

While the ⅜ rule provides a general idea of pizza consumption, several factors can influence the actual number of pizzas needed for your party. The hunger levels of your guests, any dietary restrictions, and the availability of different pizza varieties can all impact the quantity required. Additionally, considering other food options such as appetizers or sides can help strike the right balance.

When determining how many pizzas to order, it’s important to assess the hunger levels of your guests. Some individuals may have a larger appetite than others, so taking this into account can help ensure that everyone is satisfied. Additionally, if any of your guests have dietary restrictions, such as being vegetarian or gluten-free, it’s crucial to have pizza options that cater to their needs.

Pizza varieties also play a role in calculating the number of pizzas needed. Different toppings and flavors can attract different preferences, so having a variety of options can help accommodate everyone’s tastes.

Furthermore, considering other food options alongside pizza can create a well-rounded menu. Appetizers, side dishes, or desserts can provide alternatives for guests who may not be big pizza eaters or who have specific preferences. This can help ensure that there is enough variety for everyone, even if pizza is not their first choice.

Making the Decision

When it comes to determining the number of pizzas to order for your party, understanding standard pizza sizes and slice counts is essential. Familiarizing yourself with the different pizza size options available and how many slices each size typically contains will help you make an informed decision. Additionally, we’ll guide you on how to put the ⅜ rule into practice to determine the exact quantity of pizzas needed.

Standard Pizza Sizes and Slice Counts

Before placing your pizza order, it’s crucial to be aware of the standard pizza sizes and slice counts. This knowledge will enable you to estimate the number of slices each pizza will yield and assist you in calculating the total quantity required. Here is a table showcasing common pizza sizes and their corresponding slice counts:

Pizza Size Slice Count
Small (10 inches) 6 slices
Medium (12 inches) 8 slices
Large (14 inches) 10 slices
Extra Large (16 inches) 12 slices

Putting the ⅜ Rule into Practice

Now that you are familiar with the standard pizza sizes and slice counts, it’s time to apply the ⅜ rule to determine how many pizzas you need for your party. Begin by calculating the number of slices each person is likely to consume, which is approximately 3/8th of a pizza. Then, divide the total number of guests by the average number of slices per pizza. This calculation will provide you with an estimate of the quantity of pizzas required to satisfy your guests, accounting for the ⅜ rule.

Additional Considerations

In addition to the factors mentioned earlier, there are a few more considerations that can impact your pizza order. Understanding these additional elements will help you create a memorable and enjoyable pizza party experience for your guests.

Pizza Toppings: One essential aspect to consider is the variety of pizza toppings available. Take into account the preferences of your guests and choose a combination of toppings that will appeal to diverse tastes. Whether it’s classic options like pepperoni and cheese or unique choices like barbecue chicken or vegetarian toppings, offering a range of toppings will ensure everyone finds something they enjoy.

Dipping Sauces: Another way to enhance the dining experience is by providing dipping sauces for the pizzas. Whether it’s marinara sauce, ranch dressing, garlic butter, or spicy mayo, these condiments complement the flavors of the pizzas and offer additional options for guests to personalize their slices. Consider having a variety of dipping sauces available to cater to different preferences.

Party Budget: Your party budget is an important factor to consider when calculating how many pizzas to order. Take into account the cost of the pizzas, as well as any additional snacks or beverages you plan to offer. Balancing your budget while ensuring everyone is well-fed will help you create a successful and cost-effective pizza party.

Party Location: The location of your party can dictate certain considerations for your pizza order. If you’re hosting the party at your home, you have more flexibility in terms of ordering and serving the pizzas. However, if you’re hosting the party in a rented space or outdoors, you may need to consider transportation logistics and whether the location has the necessary facilities to keep the pizzas warm and easily accessible.

Time of Day: The time of day when your party takes place can influence the quantity and type of pizzas you should order. If you’re hosting a lunchtime event, guests may have lighter appetites, so you can adjust the number of pizzas accordingly. On the other hand, if your party is scheduled during dinner hours, ensure you have enough pizzas to satisfy hungry guests who may have skipped lunch.

Considering these additional factors will help you make informed decisions about your pizza order, allowing you to create a memorable and enjoyable pizza party experience for everyone. Now that you have all the necessary considerations in mind, it’s time to move on to the final section of our article where we summarize our findings and provide concluding remarks.


Planning a pizza party for 20 people requires careful consideration to ensure everyone is well-fed and satisfied. By using the ⅜ rule as a starting point, considering factors that affect pizza needs, and taking additional considerations into account, you can confidently determine the right number of pizzas for your gathering. Hosting a pizza party is an opportunity to indulge in delicious flavors, share good times, and create lasting memories with your friends and family.

Remember, it’s always better to have a little extra than to run out, so plan accordingly. Keeping in mind the average consumption per person, their hunger levels, any dietary restrictions, and the variety of pizza options available, you can make a calculated decision that will leave your guests satisfied. Ordering a range of pizza sizes and including a variety of toppings can ensure that there’s something for everyone to enjoy.

Whether you’re celebrating a milestone, hosting a casual gathering, or simply craving a pizza night with your loved ones, paying attention to the details is key. Take into account your party budget, location, and the time of day to align your pizza order with the overall ambiance and atmosphere you want to create. With careful planning and preparation, you can organize a memorable pizza party that will have everyone coming back for seconds.
