How Many Calories in a Slice of Pizza? Size & Toppings

Wondering how many calories in a slice of pizza? A typical slice of regular-crust cheese pizza contains approximately 285 calories. However, the actual amount can vary widely depending on pizza size, crust thickness, cheese, and toppings. A smaller thin-crust slice may have fewer calories, while a large pepperoni or extra-cheese slice can contain considerably more.

Pizza is one of the most popular meals because it is easy to share and comes in countless varieties. But when counting calories, not every pizza slice is equal. At Health Calculator CO, we simplify food nutrition information so you can understand serving sizes, compare pizza options, and make informed choices about your meals.

How Many Calories Are in One Slice of Pizza?

Pizza calories mainly come from three ingredients: dough, cheese, and toppings. The crust supplies most of the carbohydrates, while cheese contributes protein and fat. Meat toppings, extra cheese, and added oils can increase the total calorie count.

According to USDA-based nutrition data, one 107-gram slice of regular cheese pizza contains approximately 285 calories, 35.7 grams of carbohydrates, 12.2 grams of protein, and 10.4 grams of fat. This provides a useful reference, but it is not an exact value for every pizza.

Pizza Calories by Size: 12, 14, 16, and 18 Inches

The diameter of a pizza makes an important difference. A larger pizza generally contains more dough, sauce, and cheese. However, calories per slice also depend on how many pieces the pizza is divided into.

The 12-inch, 14-inch, and 16-inch figures are published Hungry Howie’s cheese-only pizza examples. The 18-inch value is an illustrative estimate scaled from the 16-inch pizza by surface area, not an official restaurant nutrition figure. Different recipes can produce very different results.

How Many Calories in a Slice of 12-Inch Pizza?

A 12-inch pizza is commonly called a medium pizza at many restaurants. Hungry Howie’s lists approximately 180 calories per slice for its 12-inch cheese-only pizza divided into eight pieces.

Pepperoni, sausage, or extra cheese can increase that amount. Thick-crust and specialty pizzas may also contain more calories than a standard cheese pizza of the same diameter.

How Many Calories in a Slice of Large Pizza?

A large pizza often measures around 14 inches, although restaurant sizing varies. For example, a 14-inch Hungry Howie’s cheese-only pizza contains approximately 250 calories per slice when divided into eight servings.

Large slices with generous toppings may contain 300–400 calories or more. For the most accurate estimate, check the restaurant’s nutrition information rather than relying only on the word “large.”

How Many Calories in a Slice of 16-Inch Pizza?

A 16-inch pizza slice is usually larger than a slice from a 12-inch pizza when both pizzas are cut into the same number of pieces. Hungry Howie’s lists 350 calories for one slice of its 16-inch cheese-only pizza.

A 16-inch pizza has about 78% more surface area than a 12-inch pizza. That does not guarantee 78% more calories, because crust thickness and ingredient amounts may differ, but it explains why pizza diameter matters.

How Many Calories in a Slice of 18-Inch Pizza?

An 18-inch pizza is commonly associated with extra-large, New York-style servings. Its calories can vary considerably because some restaurants cut it into eight large slices while others serve ten or twelve smaller pieces.

For illustration, an 18-inch cheese pizza prepared with similar proportions to a 16-inch, 2,800-calorie pizza would contain roughly 3,540 calories in total. That would be about 440 calories per slice if cut into eight pieces, or 295 calories if cut into twelve. These are mathematical estimates, not verified nutrition values for a particular 18-inch pizza.

How Many Calories in a Slice of Pizza With Pepperoni?

Pepperoni pizza generally contains more calories than a comparable cheese pizza because pepperoni adds fat and protein. A typical regular-crust pepperoni slice may contain approximately 300–350 calories, although smaller slices can contain much less.

USDA-based nutrition data for a Domino’s 14-inch classic hand-tossed pepperoni pizza lists approximately 308 calories per slice in one database entry. Actual current menu values may differ by crust, portion, and toppings.

How Many Calories in a Slice of Pizza With Toppings?

Pizza toppings change the amount of fat, carbohydrates, protein, and calories. Vegetable toppings usually contribute relatively few additional calories, while extra cheese and processed meats can contribute more.

To understand how toppings affect nutrition, consider these examples from Hungry Howie’s published 14-inch pizza nutrition guide.

These are restaurant-specific topping additions per slice, not universal values. Rounded zero does not mean an ingredient contains literally no calories.

How Many Calories Is 2 Pizza Slices?

Two slices of standard cheese pizza contain approximately 570 calories when each slice has 285 calories. However, two smaller slices may have fewer calories, while two extra-large or heavily topped slices could contain much more.

1 Slice of Pizza Calories at Domino’s

Domino’s pizza calories per slice depend on the pizza size, crust style, cheese portion, and toppings. A USDA-based food database lists around 278 calories for one slice of Domino’s 14-inch classic hand-tossed cheese pizza.

That historical database figure should not be treated as the current nutrition value for every Domino’s product. Thin-crust, hand-tossed, pan, and specialty pizzas can differ substantially. For a current order, use the official Domino’s nutrition information or its Cal-O-Meter where available.

Does Pizza Crust Affect the Calorie Count?

Yes. The amount of dough influences pizza calories. Thin crust often contains less dough per comparable serving, while thick, pan-style, and stuffed crust pizzas can contain more calories.

• Thin crust: Usually uses less dough, although cheese and oil still influence calories.
• Regular crust: Offers a balance of bread, sauce, and toppings.
• Thick or pan crust: May contain more dough and added oil.
• Stuffed crust: Often contains additional cheese or other fillings.

Remember to compare similar slice sizes. A small stuffed crust slice could contain fewer total calories than a very large thin-crust slice simply because the portions are different.

How to Calculate Pizza Calories Accurately

A pizza calorie calculator can help estimate the energy in your meal when restaurant nutrition details are not available. You need the total calories in the pizza and the number of equal slices, or the weight of the portion you eat.

You can also estimate calories by weight when a reliable value per 100 grams is available. This method is particularly useful for homemade pizza or unevenly cut portions.

Can Pizza Fit Into a Balanced Diet?

Pizza can be part of a balanced eating pattern when portion sizes and overall nutrition are considered. It provides carbohydrates for energy and protein from cheese or other toppings. However, some pizzas can also be high in sodium and saturated fat.

Choosing vegetables, being mindful of extra cheese and sauces, and including fruit or salad with your meal can help improve dietary variety. You do not need to avoid pizza completely to work toward healthy eating habits.

Frequently Asked Questions About Pizza Calories

Final Thoughts

So, how many calories in a slice of pizza? A standard cheese pizza slice contains around 285 calories, while larger slices, pepperoni toppings, and thicker crusts can increase the total. A 12-inch pizza slice is not necessarily comparable to a slice from a 16-inch or 18-inch pizza.

At Health Calculator CO, we encourage you to use calorie estimates as a starting point rather than exact measurements. Check serving sizes, compare ingredients, and remember that overall food quality matters alongside calories. With accurate information, you can enjoy pizza while making choices that fit your personal nutrition goals.
