A typical 14-inch regular-crust cheese pizza slice weighing about 107 grams has roughly 285 calories in USDA data, but “a slice” is not a fixed serving. Official restaurant examples run from about 210 calories for one-eighth of a 14-inch thin-crust cheese pizza to about 380 for one-eighth of a 16-inch hand-tossed cheese pizza. Size, cut, crust, cheese, sauce, oil, and toppings change the answer.
Useful examples, not one universal number
The table compares defined servings. The restaurant totals were calculated from the crust, sauce, oil where used, and “cheese-only pizza” components in Domino’s January 2026 U.S. nutrition guide. They are not estimates for every pizzeria.
| Defined serving | Calories | What the number means |
|---|---|---|
| USDA fast-food pizza chain, 14-inch cheese, regular crust; 1 slice (107 g) | About 285 | A generic database reference for a specifically described slice |
| Domino’s 14-inch crunchy thin cheese; 1/8 pizza | About 210 | 100 crust + 10 sauce + 100 regular cheese |
| Domino’s 14-inch hand-tossed cheese; 1/8 pizza | About 285 | 160 crust + 15 garlic oil + 10 sauce + 100 regular cheese |
| Domino’s 16-inch hand-tossed cheese; 1/8 pizza | About 380 | 220 crust + 15 garlic oil + 15 sauce + 130 regular cheese |
| Papa Johns original-crust cheese, individual size; 1 of 4 slices | 190 | A smaller named menu serving, not a large-pizza slice |
The examples show why an unqualified answer can mislead. “One slice” may be one-fourth, one-sixth, one-eighth, or another fraction of pizzas with different diameters. Even two slices cut from 14-inch pizzas can differ because one has thin crust and the other has a thicker base, more cheese, or finishing oil.
What changes the calorie count most?
- Diameter and cut: a wider pizza has more area, while the number of cuts determines how much of it each slice contains.
- Crust: thickness, edge width, stuffing, added oil, and dough recipe change both weight and energy.
- Cheese: light, regular, extra, and multi-cheese recipes use different amounts and products.
- Sauce and finishing fats: tomato sauce may add relatively little, while cream sauce, garlic oil, pesto, or ranch can add more.
- Toppings: pepperoni, sausage, bacon, and extra cheese commonly add more than low-energy vegetable toppings, but portion sizes vary.
- Preparation: frozen, restaurant, school, homemade, and deep-dish pizzas should not share one database entry.
How to find the best number for your slice
- Use the restaurant or package first. Match the exact product, diameter, crust, toppings, serving fraction, and current recipe. Check whether the listing is per slice, per serving, or for the whole pizza.
- Confirm the cut. A label based on one-eighth of a pizza does not apply unchanged if the pizza was cut into six pieces. Divide whole-pizza calories by the actual number of equal slices.
- Use weight when possible. If a close database entry gives calories per 100 grams, weigh the edible slice and scale that value. This is more defensible than judging size from a photograph.
- Add extras separately. Dip, chili oil, extra cheese, or a stuffed edge may not be included in the base listing.
- Keep uncertainty visible. A local slice without a recipe or weight supports a range, not an exact single calorie.
A simple weight-based example
The USDA item above provides about 266 calories per 100 grams. For a 130-gram slice that genuinely resembles that item, multiply 130 by 266 and divide by 100:
130 g × 266 calories ÷ 100 g = about 346 calories.
This method adjusts the portion, but it does not correct a poor food match. A 130-gram meat-heavy deep-dish slice can have a different calorie density from a regular-crust cheese slice. Choose the closest description before doing the arithmetic.
How toppings affect a restaurant example
Domino’s component table lists 40 calories of pepperoni for one-eighth of a 14-inch large pizza, while the regular cheese amount used when other toppings are present is smaller than the cheese-only amount. Adding 40 to a cheese-only total therefore gives the wrong recipe. Use the finished menu item or follow the guide’s component categories exactly rather than stacking isolated numbers without checking how the restaurant portions cheese.
The same caution applies to “light cheese” or removing a topping. A restaurant may alter more than one component when a customization is selected, and actual preparation has normal variation. The official guide itself notes that values can vary slightly with location and supplier.
Calories are only one part of the label
When nutrition information matters for medical care, allergy management, sodium or carbohydrate limits, or another individualized need, review the full current label and ask a qualified clinician for advice. Recipe changes and cross-contact are separate issues from calories. This article provides estimation methods, not a personalized diet prescription.
