What are Costco pizzas?
Costco pizzas come from the food court located in every Costco warehouse. They are large, round, cheese pizzas that customers can buy “by the slice” or by the whole pie. The pies are made with a thick crust and topped with a generous amount of cheese and flavorful tomato sauce. Depending on location, customers may be able to customize their pizza with additional toppings like pepperoni, sausage, mushrooms, and more.
Why Costco’s pizza is so delicious?
Costco’s pizza is made with the same ingredients in each pie. The dough is machine compressed and slightly stretched to fit the pan size. Dough is perforated with a dough docker, preventing air bubbles from forming during baking.
The different Costco pizzas sizes
Costco pizza slices come in several sizes. The most common are: 14-inch, 16-inch, and 18-inch pies. The larger the pie size, the more slices it contains—each one of them carefully cut into perfectly familiar triangle shapes that will have your mouth watering.
How many slices are in a Costco pizza?
Now that we know the different sizes of Costco pizzas, it’s time to get down to business—how many slices are in a Costco pizza? Let us break it down for you:
- For every 14-inch Costco pizza pie, there are 8 large slices.
- A 16-inch pie provides 10 pieces of cheesy goodness.
- And finally, for the biggest size available, the 18-inch pizza will give you 12 slices per pie.

What factors can affect the number of slices in a Costco pizza?
The size of the pizza is not the only factor that affects its slice count. Other elements, such as temperature and cutting methods, can also affect how many pieces come out of a single pie.
At Costco, pizzas are cut in either half or into fourths for easy sharing and to accommodate different dietary needs. So if you’re looking to get more for your money, ask the food court staff to cut your pizza into fourths. Not only will you get a greater number of slices per pie this way, but also smaller pieces that are perfect for snacking and sharing with friends.
How to calculate the number of slices in a Costco pizza
If you’re looking for an exact number of slices for a specific size, the easiest way to determine that is by using the simple formula below:
Number of slices = (pie diameter – 2) x 4
For example, let’s say you want to know how many slices are in a 16-inch Costco pizza. You can use the formula above by subtracting 2 (16-2=14) and then multiply that number by 4 (14×4=56). So, in this case, a 16-inch pie would have 56 slices.
