The number of calories in a single slice of cheese pizza varies depending on brand. A slice of Peter Piper cheese pizza, for instance, contains approximately 236 calories.
The same slice of pizza also contains a number of other things, such as 21 milligrams of cholesterol, 3.3 grams of saturated fat and 27.9 grams of carbohydrates. Alternatively, a 14-inch cheese pizza from Papa John's Pizza with an original crust contains 300 calories per slice, while the same cheese pizza with thin crust contains only 240 calories per slice. The amount of calories in a cheese pizza is not much lower compared to pizza with a range of other toppings.
