How Many Slices in a Costco Pizza?

Costco pizza is a large, thin-crust variety that’s often sold in bulk. It’s prepared with quality ingredients and pre-baked for convenience, making it perfect for feeding a large group quickly and easily. Costco pizzas come in three different sizes: small (14 inches), medium (16 inches), and large (18 inches).

Costco began selling its pizza in 1985 at its first store in Seattle, Washington, and it has become a staple of its stores ever since. The cost of Costco pizza is generally much lower than other pizzeria options and it’s consistently rated as one of the best-tasting pies in the business. It’s now one of the most popular items at Costco, especially for large groups or events.

The number of slices in each pizza size depends on the size you purchase. A small 14” pizza from Costco will yield 12 slices, a medium 16” pizza will provide 14 slices, and a large 18” pizza has enough for 16 big slices. This can vary slightly depending on how your pizza is cut, but generally speaking, these are the standard servings that come with each size. If you plan to serve more than one type of pizza at an event, it’s easy to calculate how much you need by dividing the total number of people by the number of slices per pie!

How Many People Can Costco Pizza Serve?

Depending on the size of the Costco pizza you purchase and how many slices each person will eat, you can easily estimate how many people a single pizza or multiple pizzas can serve. For instance, if you opt for a small 14” pizza, it can generously feed up to 12 people, ensuring everyone gets a satisfying slice. On the other hand, if you go for a large 18” pizza, it will provide enough food for a slightly more extensive gathering of 16 people, accommodating even more appetites.

However, considering various factors, such as individual appetites and preferences, is essential. If everyone is likely to indulge in more than one slice, or if you plan on serving multiple types of pizza to cater to diverse tastes, a helpful estimation can be obtained by dividing the total number of people by the number of slices per pie. This way, you can ensure that you have enough delicious Costco pizza to go around and satisfy everyone’s cravings.

5 Tips For Getting The Best Pizza At Costco?

Get your pizza fresh from the oven: The pizzas at Costco are usually prepared ahead of time and they spend some time in the warming area before being served to customers. So if you want to get the freshest, most flavorful pizza possible, order one straight from the oven!

Ask for the extra sauce: Most Costco pizzas come with their own special sauce, but it’s never a bad idea to ask for extra! Not only does it add flavor and moisture to the pizza, but it also helps keep the toppings in place.

Ask for more than one topping: If you’re feeling adventurous, why not try two or three different toppings on your pizza? Just make sure to let the cashier know what you want and they’ll be happy to accommodate.

Cut your own slices: For an even slice every time, cut your own pizza! This way, you can ensure that all your guests get their fair share of the pie.
