How Many Pizzas For 40 People?

Planning a party for 40 people can be a daunting task. One of the most important considerations is making sure you have enough food to serve your guests.

In this blog post, we will walk through the steps to calculate how many pizzas for 40 people based on average consumption rates.

By following our recommended process, you can ensure your next large gathering is a success without unnecessary food waste.

How Many Pizzas For 40 People?

Now let’s start addressing our main question. On average, each person will consume around 2 to 3 slices of pizza at an event. 

However, this number can vary depending on the age and gender of your guests, as well as their personal preferences and dietary restrictions. As a safe bet, it is best to plan for 3 slices per adult and 2 slices per child.

Next, consider the type and size of pizza being served. 

– A standard 14-inch large pizza typically has 8 slices

– A 16-inch extra-large pizza can have up to 12 slices. 

It is also important to factor in the number of toppings on each pizza, as this can impact the overall size and serving size per person.

According to the 3/8 pizza rule, assuming a standard large pizza with 8 slices, for a group of 40 people you would need 15 pizzas. For a mix of large and extra-large pizzas, you can estimate around 10 to 12 pizzas (depending on the number of slices of pizza is 12 or 10). 

For a group with larger appetites or if additional food options are limited, it may be best to lean toward the higher end of these estimates. With large and extra-large pizzas, you may need slightly fewer due to the larger serving size per pizza.

How To Calculate The Number Of Pizzas For 40 People?

However, you can follow the steps and formula below to simplify the process of considering how many pizzas for 40 people.

Step 1: Determine the average appetite of your guests

As mentioned above, on average each person will consume around 3 slices of pizza. However, if you know your group has bigger appetites or is predominantly made up of teenagers or young adults, you may want to adjust this number accordingly.

Step 2: Choose the size and type of pizza

Based on your calculations from step one, decide whether you will be serving mostly large (14-inch) or extra-large (16-inch) pizzas. Keep in mind that larger pizzas may have more slices, but each slice will also be larger.

Step 3: Calculate the number of slices needed

Multiply the average appetite per person (from step one) by the number of guests (40 people). 

For example:

– If each person will consume 3 slices and you have 40 guests, you would need 120 slices in total. 

40 adults x 3 slices = 120 slices

– With guests being children, if each child eats 2 slices, you have 40 kids, and you would need 80 slices.  

40 children x 2 slices = 80 slices

Step 4: Determine the number of pizzas needed

The total number of slices is divided by the number of slices on each pizza. For a standard large pizza with 8 slices:

– You would need 15 pizzas for 40 adults.

120 slices / 8 slices per pizza = 15 pizzas

– For 40 children, you would need 10 pizzas:

80 slices / 8 slices per pizza = 10 pizzas

For a mix of large and extra-large pizzas, you can do a combination of calculations to reach your desired number.

Step 5: Consider any additional factors 

Before finalizing your decision on the number of pizzas needed, consider any additional food or snacks that will also be available at the event. If there are other food options, you may be able to decrease the number of pizzas needed.

By following these steps and taking into consideration various factors such as appetite, type of pizza, and additional food options, you can determine the perfect amount of pizzas for a party of 40 people. 

Factors That Affect The Number Of Pizzas For 40 People

To accurately determine the number of pizzas needed for a group of 40 people, it is important to consider a few key factors. These include the average appetite of your guests, the types of pizza being served, and any additional food or snacks that will also be available.

The Number Of Guests

The number of guests is perhaps the most obvious factor that affects the number of pizzas needed. As the headcount increases, so does the quantity of food needed to satisfy everyone’s appetite. 

It is important to take into consideration not only the total number of guests but also their age range and any dietary restrictions they may have.

The Number Of Kids

While the number of guests is a key factor, it is also helpful to specifically look at the number of kids in the group. Children typically have smaller appetites and may not eat as much pizza compared to adults. 

Therefore, if there are a significant number of kids in the group, you may be able to decrease the overall amount of pizzas needed.

The Number Of Slices Each Person Eat 

As mentioned earlier, the average number of slices each person will eat can vary based on various factors such as age, gender, and personal preferences. If you know your guests generally have larger appetites or are big pizza lovers, it may be best to plan for more slices per person.

Types Of Pizzas You Order 

The type of pizza you order can also impact the number needed for a group of 40 people. 

For example, if everyone in the group only likes pepperoni pizza, you may need to order more pizzas compared to if you have a variety of toppings available. You should consider any dietary restrictions or preferences when selecting the types of pizzas to order.

Overall, by taking into consideration various factors such as appetite, age, dietary restrictions, and type of pizza, you can accurately calculate the number of pizzas needed for a party of 40 people. 

Other Side Dishes 

Other side dishes and food options available at the event can also affect the number of pizzas needed for 40 people. If there will be other appetizers, snacks, or main dishes served, you may be able to decrease the number of pizzas needed. 

However, if pizza is the main or only food option, plan accordingly and potentially order extra pizzas to ensure everyone is well-fed and satisfied.
