How Many Calories Are in a Slice of Pizza? Every Style and Chain, Weighed (2026)

A typical slice of cheese pizza contains about 250 to 300 calories. A thin-crust slice can be as low as 150 calories, while a slice of Chicago deep-dish reaches 480 calories or more, and a Costco food-court slice hits roughly 700. Three things set the total: slice size in grams, crust style, and toppings. Pepperoni adds about 40 calories per slice.

This guide weighs every common slice in grams, then lists calories and macros for each crust style, the major chains, toppings, and whole pizzas by size. All figures are anchored to USDA FoodData Central and each chain's published nutrition data.

How Many Calories Are in a Slice of Pizza by Crust Style?

Calories per slice vary by crust style, and the difference comes down mostly to slice weight. Neapolitan pizza is a thin, wood-fired style from Naples; New York style is large, thin, and foldable; Sicilian is thick and square; Detroit style is a thick rectangular pan pizza with crispy cheese edges; and Chicago deep-dish is a tall, buttery pie baked in a deep pan. Heavier slices hold more dough, cheese, and oil, so they carry more calories.

Crust style (1 slice, cheese)	Slice weight	Calories	Carbs (g)	Protein (g)	Fat (g)
Cauliflower crust (thin)	80 g	150	14	7	8
Thin crust	85 g	170	18	8	8
Neapolitan (wood-fired)	110 g	220	27	10	8
Flatbread	100 g	230	25	10	10
Hand-tossed (classic)	105 g	250	31	11	9
New York style	130 g	290	36	13	11
Pan / Greek	120 g	300	32	12	13
Sicilian (square)	130 g	320	37	13	13
Detroit style	140 g	350	36	16	16
Stuffed crust	150 g	360	39	16	16
Chicago deep-dish	200 g	480	43	19	26

Thin and cauliflower crusts are the lowest-calorie slices, while Chicago deep-dish, stuffed crust, and Sicilian are the highest, mostly because they weigh more.

How Many Calories Are in Chain and Frozen Pizza?

Major pizza chains like Domino's, Pizza Hut, Papa John's, Little Caesars, and Costco provide per-slice nutrition data. Generally, pan and stuffed crusts tend to have higher calorie counts than thin and hand-tossed options.

Chain pizza (1 slice)	Serving	Calories	Carbs (g)	Protein (g)	Fat (g)
Pizza Hut Thin 'N Crispy Cheese	1/8 large	190	21	9	8
Domino's Hand Tossed Cheese	1/8 large	200	26	8	7
Papa John's Original Crust Cheese	1/8 large	210	26	9	8
Domino's Hand Tossed Pepperoni	1/8 large	210	26	9	8
Pizza Hut Hand Tossed Cheese	1/8 large	240	29	11	9
Little Caesars Classic Cheese	1/8 round	240	30	11	9
Pizza Hut Original Pan Cheese	1/8 large	280	30	12	13
Little Caesars Classic Pepperoni	1/8 round	280	31	12	13
DiGiorno Rising Crust Cheese (frozen)	1/6 pizza	300	36	14	11
Pizza Hut Stuffed Crust Cheese	1/8 large	360	38	16	16
Costco Food Court Cheese	1/6 (18 in)	700	70	33	28

A single Costco food-court cheese slice (700 calories) has more calories than a McDonald's Big Mac (about 590 calories).

How Many Calories Do Pizza Toppings Add?

Most calorie variation among pizza toppings comes from meats and extra cheese, while vegetables add very little to the overall calorie count.

Topping (added to 1 slice)	Added calories
Mushrooms, onions, peppers, spinach	+5
Pineapple	+10
Black olives	+15
Ham	+20
Pepperoni	+40
Ground beef	+45
Bacon	+45
Italian sausage	+50
Extra cheese	+60

Pepperoni adds about 40 calories per slice and extra cheese about 60, while vegetable toppings add roughly 5.

How Many Calories Are in a Whole Pizza?

A whole pizza can range from about 1,000 calories for a small to 2,600 for an extra-large, with a 14-inch large cheese pizza containing around 2,000 calories.

Whole cheese pizza	Typical slices	Total calories
10 in (small)	6	1,000
12 in (medium)	8	1,600
14 in (large)	8	2,000
16 in (extra-large)	10	2,600
18 in (New York)	8	2,300

A whole 14-inch large cheese pizza (about 2,000 calories) is close to an entire day of calories for many adults.

How to Track Pizza Calories Accurately

Pizza is one of the hardest foods to estimate by eye, because a single slice ranges from 150 to 700 calories depending on size and crust. Nutrola is an AI nutrition tracking app that identifies a pizza from a photo, estimates the slice size, and returns calories and macros from a database of more than 1.8 million verified foods. It also supports barcode scanning for frozen pizzas and voice logging for quick entries. Nutrola is available from €2.50 per month and shows no ads on any tier.

How We Calculated These Numbers

Every per-slice value assumes one slice cut into eighths from a pizza of the size noted, weighed in grams. Crust-style estimates are anchored to the USDA FoodData Central generic entries for cheese pizza (regular, thin, and deep-dish crusts) and scaled by slice weight. Chain values come from each company's published nutrition data. Toppings are added on top of a cheese base. Because slice size is the single largest variable, every figure is shown with its gram weight so you can scale it to the slice you actually eat. Calories are rounded to the nearest 5 or 10. These tables are re-verified quarterly.

Frequently Asked Questions (FAQ)

How many calories are in a slice of cheese pizza?

A slice of cheese pizza generally contains between 250 to 300 calories, depending on the crust style and size. For example, a standard hand-tossed slice is around 250 calories, while a New York-style slice can reach up to 290 calories.

How many calories are in a slice of pepperoni pizza?

A slice of pepperoni pizza typically adds about 40 calories to the base cheese slice count. Therefore, if a cheese slice is around 250 calories, a pepperoni slice would be approximately 290 calories.

How many calories are in a whole pizza?

The total calorie count for a whole pizza varies significantly based on size and style. A small pizza may contain around 1,000 calories, while a large 14-inch pizza can have about 2,000 calories, making it important to consider portion sizes.

Which pizza crust has the fewest calories?

The crusts with the fewest calories are typically thin and cauliflower crusts. A slice of cauliflower crust pizza can be as low as 150 calories, while a thin crust slice usually ranges from 170 to 190 calories.

How many calories are in a Costco pizza slice?

A slice of cheese pizza from Costco's food court contains about 700 calories. This makes it one of the higher-calorie options available from major pizza chains.

Is pizza bad for weight loss?

Pizza can fit into a weight loss plan if portioned appropriately. Opting for thinner crusts and adding vegetable toppings can help reduce calorie intake, while including protein can enhance satiety.

Key Takeaways

• A cheese slice is typically 250 to 300 calories.
• Slice size in grams is the biggest variable affecting calorie count.
• Thin and cauliflower crusts are the lowest-calorie options.
• Deep-dish, stuffed crust, and Costco slices are among the highest in calories.
• Pepperoni adds about 40 calories per slice, and extra cheese adds about 60.
