Pizza Slice Weight by Style
Style and diameter are the two biggest variables. A pizza cut into 8 slices means a slice weight that scales with total size.
| Style | Pizza size | Slice weight | Calories |
|---|---|---|---|
| Cheese (chain large) | 14 in / 1/8 | 3.8 oz / 107g | ~285 cal |
| Thin crust | 12 in / 1/8 | 2.5-3 oz / 70-85g | 190-220 cal |
| New York | 18 in / 1/8 | 4.6-6.3 oz / 130-180g | 300-350 cal |
| Chicago deep dish | 12 in / 1/8 | 7-10 oz / 200-280g | 350-450 cal |
| Detroit square | 8x10 in / 1/8 | 5-6 oz / 140-170g | 320-400 cal |
| Personal pan | 6 in / 1/4 | 2.5-3 oz / 70-80g | 180-220 cal |
| Frozen (DiGiorno) | 12 in / 1/6 | 3-4 oz / 85-110g | 270-320 cal |
How Toppings Change Weight
Toppings add real weight. Pepperoni adds 10-15g per slice (~50 cal). Sausage adds 15-25g (~70 cal). Veggies add 10-20g (~25 cal). Extra cheese adds 20-30g (~80 cal). A meat lover's slice can weigh nearly double a plain cheese slice and hit 400+ calories.
Why Pizza Sizes Are Confusing
A "large" at Domino's, Pizza Hut, and Papa John's is 14 inches. But a New York pizzeria large is 18 inches. Costco pizza is 18 inches. Pizza area scales with the square of the diameter, so an 18-inch pizza is 65% bigger than a 14-inch pizza, not 29%. Slice weight scales the same way.
Estimate Slice Weight Without a Scale
A standard 14-inch slice is roughly the size of two adult hands side by side (~107g). Thin crust = 70% of standard. Deep dish = roughly 2x. For an instant estimate, photograph the slice with our AI scale tool.
Quick Calorie Math
For chain pizza, multiply slice weight in grams by 2.6 cal/g for cheese, 2.9 cal/g for pepperoni, 3.1 cal/g for meat lover's. So a 150g pepperoni slice = ~435 cal.
