Scale to GramsHow Much Does a Slice of Pizza Weigh? Calories by Size & Type
Average Pizza Slice Weight by Type
Pizza weight varies significantly by style and diameter. A regular cheese slice from a 14-inch (large) pizza weighs approximately 107 grams (3.8 oz) and is typically cut into 8 slices. A New York-style slice is larger and thinner, weighing about 130-180 grams (4.6-6.3 oz) from an 18-inch pizza cut into 8 wide slices. A thin crust slice weighs about 70-85 grams (2.5-3 oz) because less dough means less weight. A deep dish or Chicago-style slice weighs 200-300 grams (7-10.5 oz) due to the thick, buttery crust and heavy cheese and sauce layers. A personal pan pizza (6-inch) cut into 4 slices produces slices weighing about 70-80 grams each. Frozen pizza slices tend to weigh less than restaurant pizza — a typical frozen slice is 85-110 grams.
How Toppings Change the Weight
Toppings add more weight than most people realize. A plain cheese slice is your baseline at about 107 grams. Adding pepperoni increases weight by about 10-15 grams per slice. Sausage adds 15-25 grams. Vegetables (mushrooms, peppers, onions) add 10-20 grams. A meat lover's slice with multiple meat toppings can weigh 150-180 grams — nearly double a plain cheese slice. Extra cheese adds 20-30 grams. The heaviest common pizza is a deep dish meat lover's, which can weigh over 300 grams per slice. The lightest is a thin crust Margherita at around 70 grams. When estimating calories, the weight difference between a loaded and a plain slice can mean 100-200 extra calories per slice.
Calories by Pizza Type
A standard large cheese pizza slice (107g) has about 285 calories, with 12g of fat, 36g of carbs, and 12g of protein. A thin crust cheese slice has about 190-220 calories due to less dough. A deep dish cheese slice runs 350-450 calories because of the thick, oil-rich crust. A New York-style cheese slice has about 300-350 calories — it is bigger but thinner, so calories scale with size rather than thickness. Pepperoni adds roughly 40-60 calories per slice. A meat lover's slice from a major chain typically has 350-400 calories. The most calorie-dense common slice is deep dish meat lover's at 450-550 calories. For calorie tracking, weighing your slice gives you the most accurate number — multiply the weight in grams by the calories-per-gram for that pizza type.
Why Pizza Sizes Are Confusing
A "large" pizza means different things at different restaurants. Domino's large is 14 inches. Pizza Hut large is 14 inches. Papa John's large is 14 inches. But a New York pizzeria large is often 18 inches. A Costco pizza is 18 inches. And some local shops sell "large" at 16 inches. This matters because pizza area scales with the square of the diameter — an 18-inch pizza has 65% more pizza than a 14-inch pizza, not just 29% more. So a "slice" from an 18-inch pizza weighs significantly more than a "slice" from a 14-inch pizza, even when both are cut into 8 pieces. When tracking calories, knowing the pizza diameter matters as much as knowing the toppings.
Estimating Pizza Weight Without a Scale
For a quick estimate, use the hand comparison method. A standard 14-inch pizza slice is roughly the size of two adult hands placed side by side — about 107 grams. If the slice is significantly larger or smaller than that, adjust your estimate proportionally. The thickness of the crust is your second clue: thin crust where you can see light through it weighs roughly 70% of a standard crust slice. Deep dish that is over an inch thick weighs roughly double a standard slice. You can also photograph your pizza slice next to a reference like a fork or plate and use an AI tool like Scale to Grams for an instant weight and calorie estimate — especially useful when eating out and trying to log your meal quickly.
