Planning a family dinner or getting together with friends? Pizza is always an easy option when you need something tasty that everyone can share. However, before placing an order, it’s worth knowing how much food you’re actually getting. Costco is well known for its large food court pizzas, which offer generous portions without making customers spend a fortune.
So, how many slices are in a Costco pizza? A whole Costco pizza is generally cut into 12 slices. That’s quite a lot of pizza in one box, especially considering its large size. Whether you’re feeding your family, organising an office lunch or having friends over for the weekend, knowing the slice count can help you plan your meal.
Let’s look at the size, portions and serving options to give you a better idea of what to expect.
How Many Slices Come in a Whole Costco Pizza?
A standard whole Costco pizza usually comes with 12 slices. Each piece is fairly large, so don’t expect the small portions you might get from some regular takeaway restaurants.
The pizza is designed to provide plenty of food from a single order. It comes with a generous base, tomato sauce, melted cheese and your choice of available toppings. For families and groups, this makes sharing much easier.
Of course, cutting arrangements can sometimes vary between locations. However, 12 slices is the commonly reported number for a whole Costco pizza.
What Is the Size of a Costco Pizza?
Costco pizza is a bit larger than most takeaway pizzas. A typical food court pizza measures 18 inches across.
By comparison, most takeaway pizzas measure between 10 and 14 inches. The additional thickness gives Costco pizzas a larger surface for cheese, sauce, and toppings.
This size is good for a birthday party, family meal or lunch for your colleagues. You don’t have to buy lots of small pizzas when you can buy one large one for everyone.
Consider that the number of people it will feed depends on how hungry your guests are.
How Many People Can One Costco Pizza Feed?
One Costco pizza will usually feed around four to six people, but this isn’t a strict rule. Some people may be content with just one or two slices, while others might quickly finish three.
If pizza is the main course, consider everyone’s appetite before ordering. Children may eat smaller portions and teenagers and adults may want more.
Here’s a quick breakdown to help you estimate:
| Number of people | Approximate slices per person |
| 2 people | 6 slices |
| 3 people | 4 slices |
| 4 people | 3 slices |
| 6 people | 2 slices |
| 8 people | 1–2 slices |
These numbers are only estimates, but they give you a useful starting point. If you’re expecting a large group, ordering an extra pizza is always a safer option than running out halfway through the meal.
Why Is Costco Pizza So Popular?
Costco pizza is the choice of many customers at food courts, mainly because it’s filling, easy to take out and packs a lot of nutrients for the price.
The largest slice of pizza they have is large enough to share among multiple people. If you have a big family, you could order up several small pizzas for less than $10.
Another benefit is that customers don’t need to spend hours at the store shopping. After visiting stores, they can come in and grab something to eat without having to make dinner at home. You can even order a whole pizza for your family or a relaxing evening with friends.
Another thing that Costco customers rely on is the familiarity of the menu. The variety of pizza options at Costco isn’t too complicated, making it easier for customers to find something that everyone will enjoy.
Popular Costco Pizza Varieties
Costco usually carries classic pizza flavours, but the menu can vary by warehouse and country.
Cheese Pizza
Sometimes, you have to go simple. Cheese pizza consists of tomato sauce, melted cheese and freshly baked crust. It’s a favourite dish for both children and adults, especially those who aren’t picky about toppings.
It’s a good dish for a family potluck because most people enjoy the simple flavor.
Pepperoni Pizza
You may prefer something a little more flavorful like pepperoni pizza, a pizza made with melted cheese and tomato sauce and seasoned pepperoni slices.
The combination gives each bite a savoury taste that will appeal to those who prefer meat-topped pizzas.
Both are popular options, though check at your local Costco food court to see if they’re available.
Costco Pizza vs Regular Takeaway Pizza
When comparing Costco pizza to the usual takeaway options, size is one of the biggest differences.
Most 12-inch pizzas come in eight slices, whereas one Costco whole pizza has 12. More slices don’t always mean more food.
Some examples: A smaller pizza cut in 12 pieces may be less satisfying than a larger pizza divided into eight portions. In those cases, it’s worth looking at the diameter of the pizza as a whole and not just counting the slices.
Costco’s 18-inch pizza is fairly large, which makes it great for sharing between friends or family.
Tips for Ordering Costco Pizza for Groups
Trying to figure out how much pizza to order does not have to be difficult. Just count the number of your guests and consider whether pizza will be your main dish.
For a small family dinner, you might be satisfied with one whole pizza. If you’re celebrating your birthday at home or at work, you may need two or more pizzas depending on the number of people attending.
Also serve a few sides. Garlic bread, salads and drinks can turn a simple pizza order into a full meal. If you want to cater to everyone, try serving a mixture of cheese and pepperoni pizzas.
Check with your local Costco before placing a large order to see what prices they are offering, what flavors they have available and how they make your order. This will help you avoid surprises at the last minute, especially if you’re planning an event.
