How Many Calories Are in A Pizza Slice
How Many Calories Are in Your Favorite Pizza Slice? A Comprehensive Breakdown
Pizza is a universally beloved food, known for its endless combinations of crusts, sauces, and toppings. Whether you enjoy a classic Margherita or a meat-laden supreme, pizza offers something for every taste. However, while pizza may be delicious, it’s not always the most diet-friendly option. The number of calories in a pizza slice can vary significantly depending on ingredients, size, and preparation. In this article, we’ll take a closer look at the calorie content of various pizza types and factors that contribute to their overall nutritional profile.

Caloric Breakdown: Crust Matters
One of the largest contributors to the calorie content of a pizza slice is the crust. The thicker the crust, the more calories you can expect to consume. Here’s how different types of pizza crusts affect the calorie count per slice:
- Thin Crust: Thin crust pizzas are often seen as a lighter option. A single slice of thin-crust cheese pizza (about 12 inches in diameter) typically contains around 170-200 calories. While the reduced dough helps to lower calories, the overall count still depends on toppings and portion size.
- Regular Crust: A regular or hand-tossed crust falls somewhere in the middle in terms of calories. A slice from a 12-inch pizza may range between 200-300 calories, depending on the thickness of the dough and the ingredients.
- Thick Crust/Deep Dish: Deep-dish or thick-crust pizzas can be much more calorie-dense due to the higher amount of dough. A single slice of deep-dish pizza (about 14 inches in diameter) can contain anywhere from 350-450 calories or more, especially if loaded with toppings like cheese and meat.
The Sauce: A Hidden Contributor
Pizza sauce often gets overlooked when calculating the calorie content of a pizza, but it can play a significant role. Most pizza sauces are tomato-based and contain a relatively low number of calories—about 10-20 calories per tablespoon. However, many sauces also contain sugar and oil, which can increase the overall caloric content. Creamy sauces, such as white garlic sauce or Alfredo, are much higher in calories, sometimes adding an extra 50-100 calories per slice.
Cheese: The Star Ingredient
Cheese is the signature topping that gives pizza its flavor and texture, but it’s also a major contributor to its calorie count. A standard slice of cheese pizza (regular crust) contains around 200-300 calories, with a significant portion of those calories coming from cheese. On average, a slice with about 2 ounces of mozzarella cheese contains approximately 140 calories, primarily from fat.
Pizza variations that use additional cheese types, such as Parmesan, ricotta, or cheddar, will naturally add more calories. A “double cheese” or “extra cheese” pizza can easily bump the calorie count by 100-200 per slice.
Toppings: Choose Wisely
Toppings are one of the most customizable aspects of pizza and also one of the biggest factors influencing calorie counts. While some toppings are relatively low in calories, others can add hundreds of calories to a single slice. Here’s a look at common pizza toppings and their calorie contributions:
- Pepperoni: Pepperoni is one of the most popular pizza toppings, but it’s also high in calories. A single slice of pepperoni pizza can add around 50-100 calories per slice, depending on how much is used.
- Vegetables: Veggies like onions, mushrooms, bell peppers, and spinach are low-calorie options, typically adding less than 20 calories per slice. They also offer added nutritional benefits like fiber and vitamins.
- Meats: Heavier meat toppings, such as sausage, bacon, and ham, can significantly raise the calorie count. For instance, sausage can add up to 150 calories per slice, while bacon adds about 40-60 calories.
- Healthy Alternatives: Opting for lean meats like grilled chicken or turkey can help you enjoy the flavor without the calorie overload. Grilled chicken typically adds around 30-50 calories per slice.
Portion Size: How Much Are You Really Eating?
Another factor to consider is portion size. Pizza slices can vary significantly in size, especially at popular chains. A slice from a 12-inch pizza is much smaller than a slice from a 16-inch pizza, but people often assume they’re consuming the same number of calories per slice. In reality, a large pizza slice could easily contain double the calories of a smaller slice. For example, a slice from an extra-large pizza (16-18 inches) may contain 400-500 calories or more, depending on the toppings.
Pizza from Popular Chains: A Caloric Overview
Most pizza lovers have a go-to chain, whether it’s Domino’s, Pizza Hut, or Papa John’s. Here’s a breakdown of the average calories per slice from some of these popular chains:
- Domino’s: A slice of Domino’s Hand-Tossed Cheese Pizza (14-inch) contains approximately 290 calories. A slice of their Thin Crust Cheese Pizza contains around 230 calories.
- Pizza Hut: A slice of Pizza Hut’s Hand-Tossed Cheese Pizza (14-inch) contains about 300 calories. Their Thin ‘N Crispy Cheese Pizza comes in at around 260 calories per slice.
- Papa John’s: A slice of Papa John’s Original Crust Cheese Pizza (14-inch) contains roughly 290 calories, while their Thin Crust version contains about 230 calories per slice.

Making Healthier Pizza Choices
While pizza can be high in calories, there are several ways to make it a healthier option:
- Opt for Thin Crust: Choosing thin crust over regular or thick crust can save you 50-100 calories per slice.
- Load Up on Veggies: Toppings like spinach, mushrooms, and peppers not only add flavor but also contribute fewer calories.
- Skip the Extra Cheese: Reducing the amount of cheese or opting for lighter cheese options can significantly lower calorie intake.
- Portion Control: Limit yourself to one or two slices instead of indulging in a whole pizza to keep calorie consumption in check.
Conclusion
Pizza is undeniably delicious, but it’s important to be mindful of the calorie content, especially when considering different crusts, sauces, cheeses, and toppings. By making small adjustments, such as choosing thin crust, loading up on vegetables, and being cautious with high-calorie toppings, you can still enjoy pizza while keeping your calorie intake in check. Whether you’re indulging in a classic slice or creating a healthier version, understanding the factors that influence pizza’s calorie count is key to making informed choices.
