How many pizzas will you need? How many slices of pizza per person?

It is generally agreed that one slice of pizza per person is a good rule of thumb to follow when ordering pizza for a group. However, there are always exceptions to the rule. If you have a group of people with heartier appetites, you may want to consider ordering two pizzas per person. For smaller groups, or groups where some members are not big fans of pizza, one pizza may be enough.
If you are unsure about how much pizza to order, it is always better to err on the side of caution and order too much rather than too little. No one likes being stuck eating cold leftover pizza for breakfast the next day!
Order pizzas for kids and adults

When it comes to pizza, adults and kids often have very different opinions. Adults tend to prefer more complex flavor profiles, while kids usually just want cheese and maybe some pepperoni. Because of this, you may want to consider ordering one pizza per adult and one pizza per two children. This will ensure that everyone has at least one slice of pizza they enjoy, and there are plenty of leftovers for the adults to snack on later.
Order pizzas for a group

If you are feeding a large group of people, you may want to consider ordering a few extra pizzas. A good rule of thumb is to order one pizza for every four people. This will ensure that there is plenty of food for everyone, and you will have leftovers in case anyone gets hungry later.
The Pizza Formula
If you don’t have access to a calculator (or if you just want to know the math behind it), there is a formula you can use to determine how many pizzas to order. The general rule of thumb is that each person will consume one slice of pizza per hour.
So, if you have 30 people attending your party, and it’s scheduled to last 3 hours, you would need to order 90 slices of pizza, or 15 pizzas.
Things to take into account when ordering pizzas for a group
Your guest’s appetite
The more the guests, the hungrier they are likely to be. If you have a big group of people coming over, chances are that they would want second servings. You might even consider ordering an extra pizza or two just in case everyone gets really hungry.
The number of adults and children
If you are having a party with both adults and children, you might want to order an extra pizza or two. This is because children tend to eat less than adults and they might not be as interested in the toppings that you have to offer.
Are there any diet restrictions?
You should also consider any diet restrictions that your guests might have. If you are inviting someone who is vegetarian, for example, you might want to order a pizza with vegetable toppings. This way, they will be able to enjoy the pizza without having to worry about their dietary restrictions.
Consider the allergies
Finally, you should also consider any allergies that your guests might have. If you are inviting someone who is allergic to gluten, for example, you might want to order a gluten-free pizza. This way, they will be able to enjoy the pizza without having to worry about their allergy.
The occasion
You should also consider the occasion when you are ordering pizza. If you are having a casual get-together, for example, you might want to order a few different types of pizza. This way, people can sample a bit of everything. On the other hand, if you are having a formal event, you might want to stick to one or two types of pizza.
How many slices are there per pizza?
Make sure you know how many slices are in a pizza before you place your order. This way, you can be sure that everyone gets the amount of pizza that they want. Most pizzas are cut into eight slices, but some restaurants will cut their pizzas into 12 or 16 slices.
Next, we will walk you through tips for a pizza order.
Tips for a pizza order

Get pizzas delivered fresh and warm
If you want your guests to enjoy the pizza at its best, make sure to get it delivered fresh and warm. This way, they will be able to taste all of the flavors and the crust will be crispy.
Get pizzas sliced according to the formula
When you order pizza, make sure to ask for it to be sliced according to the formula. This way, everyone will get an equal number of slices and no one will go home hungry.
Tips to choose toppings for your pizzas
Cheese pizzas are a safe choice
Cheese pizza can be more preferable for some people in a group because it is a classic, safe choice that everyone can agree on. If you are looking for more of an adventure, choose 2-3 different types of pizza with unique flavor profiles. This way, there is something for everyone and people can sample a bit of everything. Some crowd-pleasing topping combinations include:
- Pepperoni and sausage
- Ham and pineapple
- Barbecue chicken
- Mushroom and olive
- Spinach and feta
If you know the preferences of your guests, you can order specialty pizzas
If you know that your guests have particular pizza preferences, it can be helpful to order a few specialty pizzas. This way, everyone can get their favorite slice and you don’t have to worry about anyone going home hungry.
If you’re on a budget, think of thick crust pizzas
If you want to save money, order thick crust pizzas instead of thin crust. They tend to be more filling and will stretch further than their thinner counterparts. Plus, everyone loves a good slice of deep dish!
How many pizzas are enough for different numbers of people?

Now that you know all of the factors to consider when ordering pizza, how many pizzas should you order for your event? Here is a helpful guide:
- 5 people = 2-3 pizzas
- 10 people = 4-6 pizzas
- 15 people = 6-9 pizzas
- 20 people = 8-12 pizzas
- 25 people = 10-15 pizzas
Remember, it is always better to err on the side of caution and order too much pizza than not enough. This way, everyone can have seconds (or thirds!) and no one will go home hungry. So, next time you’re wondering how many slices of pizza per person, remember this guide. With a little planning, you can be sure that everyone will have a slice (or two!) of the pie.
Pizza types affect the number of pizza you need
If you want to switch things up and order something other than traditional pizza, there are a few things to keep in mind. First, think about how many slices are in each pie. For example, a 12-inch deep dish pizza will have fewer slices than a 16-inch thin crust pizza. Second, consider the toppings. If you are ordering a cheese pizza, you might need more pies than if you are ordering a pizza with lots of toppings. This is because cheese pizzas tend to be less filling than pizzas with multiple toppings. Finally, remember that everyone has different appetites. Some people might want two slices of pizza while others might only want one. With this in mind, it is always better to order too much pizza than not enough.
Here is a guide for how many pizzas you will need, depending on the type of pizza:
- Thin crust pizza: 1-2 pies per person
- Deep dish pizza: 1 pie per person
- Pizza with multiple toppings: 1-2 pies per person
- Cheese pizza: 2 pies per person
The quantity you need also depends on the pizza sizes
Now that you know how many pizzas to order depending on the type, it’s time to think about pizza sizes. The most common pizza sizes are 12 inches, 14 inches, and 16 inches. If you are feeding a large group of people, it is best to order multiple large pizzas rather than a few small ones. This way, everyone can have more than one slice and no one will go home hungry.
Here is a guide for how many pizzas you will need, depending on the size:
- 12-inch pizza: 1-2 pies per person
- 14-inch pizza: 2 pies per person
- 16-inch pizza: 2-3 pies per person
As you can see, there are a lot of factors to consider when deciding how many pizzas to order for your group. The best way to ensure that everyone gets enough to eat is to err on the side of caution and order more pizza than you think you will need. With a little planning, you can be sure that everyone will have a slice (or two!) of the pie.
