Costco pizza is a fan favorite for its size and affordability. It’s a go-to for parties, family dinners, or quick meals. Knowing the slice count helps plan your purchase.
The food court’s massive pizzas are a great deal. Their large size and low price make them perfect for feeding a crowd. But how many slices come in one pie?
This guide explains Costco pizza sizes, slice counts, and ordering tips. You’ll learn how to make the most of this budget-friendly meal. Let’s break it down.
Why Costco Pizza Is a Great Choice
Costco’s food court is famous for value. The pizza is large, tasty, and priced low. It’s a top pick for shoppers and event planners.
Each pizza is made fresh with quality ingredients. The size and price make it ideal for groups. It’s a reliable option for any occasion.
The consistent quality draws crowds. Whether for a party or a quick bite, Costco pizza delivers. Understanding its size and slices ensures you order enough.
How Many Slices In A Costco Pizza Size
A standard Costco pizza is 18 inches in diameter. It’s cut into 12 equal slices for whole pies. Each slice is about 4.5–5 inches wide at the crust.
Individual slices sold for $1.99 are larger. These are cut from a whole pizza into 6 slices. This makes them twice the size of a whole pie slice.
The 12-slice cut is standard for whole pizzas. You can request a 6-slice or 18-slice cut, but it’s not guaranteed. Availability depends on the food court’s workload.
Costco Pizza Sizes and Options
Costco offers one pizza size: 18 inches. This is larger than most chains’ extra-large pies. It’s equivalent to an XL pizza at Domino’s or Pizza Hut.
Toppings are simple: cheese, pepperoni, or half-and-half. The combo pizza with veggies and meats was discontinued in 2020. Some locations offer a Four Meat Pinsa-style pizza.
Cheese pizzas use a mozzarella-provolone blend. Pepperoni pizzas have 60 slices of pepperoni for even coverage. The half-and-half option splits toppings evenly.
Costco Pizza Price and Value
A whole 18-inch pizza costs $9.95 in 2025. Each slice averages $0.83, making it a bargain. Individual slices cost $1.99 but are larger.
Compared to competitors, Costco’s price is unbeatable. A 16-inch Domino’s pizza costs $18.24, while Pizza Hut’s 14-inch is $16.29. Costco’s larger pie is nearly half the price.
Buying a whole pizza saves money. Two Costco pizzas cost $19.90, close to one competitor’s pie. This makes it ideal for large groups.
Pizza Slice Comparison Table
| Pizza Source | Slice Count (Whole Pie) | Price per Slice (USD) |
|---|---|---|
| Costco | 12 | $0.83 |
| Domino’s | 10 (16-inch) | $1.82 |
| Pizza Hut | 8 (14-inch) | $2.04 |
Costco’s 12 slices offer the best value. Each slice is larger than competitors’ at a lower cost. This table highlights the savings.
How Many People Does a Costco Pizza Feed?
A single Costco pizza feeds 4–6 adults. Each person typically eats 2–3 slices, depending on appetite. For kids, one slice is often enough.
For a party of 10, 2–3 pizzas are sufficient. Larger groups, like 20 adults, may need 5–7 pizzas. Always order an extra pie to avoid running out.
Consider other food options to stretch the pizza. Pair with Costco’s Caesar salad or hot dogs. This ensures everyone is satisfied.
Ordering Costco Pizza: Tips and Tricks
Order at the food court counter or kiosk. Kiosks accept credit cards, while counters take cash. Call ahead to reduce wait time, typically 15–30 minutes.
Request a “well-done” pizza for a crispier crust. This works best during off-peak hours. Order early and pick up after shopping to save time.
You need a Costco membership to buy pizza. Some locations allow non-members with a Costco Shop Card. Check local policies before visiting.
Storing and Reheating Costco Pizza
Store leftovers in an airtight container or foil. Refrigerate within 2 hours for up to 3–4 days. Freeze for 1–2 months to prevent spoilage.
Reheat in an oven at 375°F for 8–10 minutes. An air fryer at 300°F for 2–3 minutes works for single slices. Microwaves can make the crust soggy.
Wrap slices individually before freezing. This prevents freezer burn and makes reheating easier. Thaw in the fridge before reheating for best results.
Nutritional Information
A whole cheese pizza has 4,260 calories, while pepperoni has 3,880. Each slice from a whole pie is 355 calories (cheese) or 325 calories (pepperoni). Individual slices are double, at 710 and 650 calories.
Cheese pizza has 24 ounces of cheese, while pepperoni has 14 ounces. Pepperoni slices include 60 pieces for even distribution. High sodium and fat make it a treat, not a daily meal.
Pair with a salad to balance nutrition. Costco’s Caesar salad is $6.99 and serves 2–4. This makes for a more complete meal.
Planning a Party with Costco Pizza
Costco pizza is perfect for events. For 25 adults and 10 kids, order 8–10 pizzas. This assumes 1.5 slices per adult and 1 per child.
Call ahead for large orders. Provide 30 minutes to ensure readiness. Double-cut pizzas into 24 slices for kids’ parties to stretch portions.
Add sides like hot dogs ($1.50) or cookies ($2.49). These keep costs low and guests happy. Check food court hours, as they close on major holidays.
Why Costco Pizza Stands Out
Costco uses a pizza cutting guide for uniform slices. A metal tool ensures 12 even slices every time. This keeps portions consistent across locations.
The 18-inch size is larger than most chains. The $9.95 price hasn’t changed in decades, despite inflation. Bulk ingredient purchasing keeps costs low.
The crust is chewy yet structured, with tangy sauce and stretchy cheese. It’s not gourmet but satisfies crowds. Its value and size are unmatched.
Creative Uses for Leftovers
Turn leftover pizza into a casserole. Add sauce and cheese, then bake until bubbly. It’s a fresh take on leftovers.
Use crusts for homemade croutons. Toss with olive oil and herbs, then bake. Toppings can fill omelets or quesadillas for quick meals.
Freeze extra slices for later. Wrap tightly to maintain flavor. Reheat in an oven for the best texture.
Summary
A Costco pizza is 18 inches and cut into 12 slices for whole pies. Individual slices are larger, cut into 6 pieces, and cost $1.99 each. A whole pie at $9.95 feeds 4–6 adults, making it a great value.
Order ahead or use kiosks to save time. Store leftovers properly and reheat in an oven or air fryer. The consistent quality and low price make Costco pizza a top choice.
Plan parties with 2–3 pizzas for 10 people or more for larger groups. Pair with sides for a complete meal. Enjoy this budget-friendly, crowd-pleasing option.
