A single slice of cheese pizza from a standard 14-inch pie contains roughly 250 to 350 calories. That range shifts depending on the crust style, toppings, and where the pizza comes from, so the real answer depends on what kind of slice you’re eating.
Calories by Topping
Plain cheese pizza sits at the lower end of the spectrum. A slice from a regular-crust, 14-inch pizza cut into eight slices typically lands between 250 and 300 calories. Adding pepperoni bumps that up modestly, putting most slices in the 300 to 350 range. The meat itself adds fat and protein without changing the slice size much.
Meat-lovers or “the works” pizza is a different story. A single slice of a loaded meat pizza can top 500 calories, along with 1,200 milligrams of sodium and 40 grams of carbs. That means two slices of a meat-lovers pie can exceed the calorie content of a full fast-food meal.
Vegetable toppings like mushrooms, peppers, and onions add very few calories compared to meat or extra cheese. If you’re looking to load up a slice without dramatically increasing the calorie count, vegetables are the most forgiving option.
What’s Actually in a Slice
Beyond calories, a standard slice of cheese pizza (about 107 grams) from a typical chain contains roughly 35.6 grams of carbohydrates, 10.4 grams of fat, and 12.2 grams of protein. Carbs make up the bulk of the energy, mostly from the dough. The fat comes from cheese and oil, while the protein comes from both the cheese and the crust.
That macronutrient profile means pizza isn’t purely empty calories. A slice delivers a decent hit of protein, roughly equivalent to two eggs. But the carb-to-protein ratio is high, and the sodium content across most commercial pizza is significant, often 600 to 800 milligrams per slice for a basic cheese.
Calories at Major Chains
The calorie count varies more than you might expect between chains, largely because of differences in dough thickness, cheese quantity, and slice size.
- Little Caesars: A slice of their large 14-inch Classic Cheese runs 280 to 300 calories.
- Pizza Hut: A medium hand-tossed cheese slice comes in at 260 to 300 calories.
- Domino’s: A medium hand-tossed cheese slice ranges from 200 to 290 calories, depending on crust type.
- Papa John’s: Their Ancient Grains Cheese Pizza works out to about 250 calories for a comparable portion.
Keep in mind that “medium” and “large” aren’t standardized across chains. A large at one chain may be 14 inches while a medium at another is 12 inches, which changes how many slices you get and how big each one is. Always check whether the calorie figure you’re looking at is based on a six-slice, eight-slice, or ten-slice cut.
Crust Makes a Bigger Difference Than You Think
Thin crust reduces calories per slice because there’s simply less dough. A thin-crust cheese slice can come in 30 to 50 calories lower than the same pizza on a hand-tossed or pan crust. Deep dish and stuffed crusts push in the opposite direction, sometimes adding 100 or more calories per slice compared to a regular crust.
Cauliflower crusts have become a popular alternative, but they don’t always save as many calories as people assume. A cauliflower-crust cheese pizza from Trader Joe’s works out to about 250 calories for one-third of the pie, which is comparable to a regular-crust slice from most chains. The carb count is usually lower, but the calorie savings can be minimal because fat and cheese still dominate. A plain cauliflower pizza crust on its own (like Outer Aisle’s single-serving 8-inch crust) runs about 120 calories before any toppings.
Frozen Pizza vs. Delivery
Frozen pizzas tend to be slightly smaller and slightly lower in calories per slice than delivery, but the gap isn’t dramatic. A frozen cheese pizza slice generally falls in the 230 to 280 calorie range, while the same slice from a delivery chain sits closer to 260 to 320. The difference comes down to portion size: frozen pizzas are often 10 to 12 inches, producing smaller slices than the 14-inch pies most chains serve.
Where frozen pizza can surprise you is in sodium. Some frozen brands pack as much or more sodium per slice as restaurant pizza because salt is a key part of preserving flavor during freezing. If sodium is a concern, check the nutrition label rather than assuming frozen is automatically the lighter choice.
How Slice Count Changes the Math
One of the most common sources of confusion is that calorie counts assume a specific number of slices per pie. Most nutritional data for a 14-inch pizza assumes eight slices. If your local shop cuts the same pie into six slices, each slice is 33% larger and contains roughly 33% more calories. A “slice” from a New York-style pizzeria, where pies are often 18 inches and cut into eight oversized slices, can easily hit 400 to 450 calories for plain cheese.
The simplest way to estimate is to think in terms of the whole pie. A full 14-inch cheese pizza from a typical chain contains roughly 2,000 to 2,400 calories total. Divide by however many slices are actually in front of you, and you’ll get a more accurate number than relying on generic per-slice figures.
