• Chicago-style deep-dish pizza has the highest mainstream estimate, at about 535 calories per slice.
• Crust thickness and slice size change calories more than most toppings.

The Short Answer: Pizza Calories By Style

A plain cheese slice contains about 250 to 300 calories. That range fits standard American chain pizza, not every pizza style.

A Neapolitan slice has around 170 calories, while a Chicago deep dish slice has over 500 calories. The word “slice” gets tricky because one slice might mean a small Neapolitan quarter or a heavy, deep dish slab. Use pizza style first, then toppings, to estimate the real number.

All calorie figures in this article are sourced from USDA FoodData Central and major chain nutrition pages.

Pizza Calories By Style at a Glance

Calories By Pizza Style: The Full Breakdown

Neapolitan Pizza, ~170 Calories Per Slice

Neapolitan pizza has the lightest mainstream calorie count because the pizza is smaller, the crust is thin, and the toppings stay simple. A traditional pie often measures 10 to 12 inches and gets cut into 4 to 6 slices.

The dough uses little oil. The sauce uses crushed tomatoes. Classic Margherita uses fresh mozzarella instead of a thick blanket of shredded cheese. That keeps the calorie count near 170.

Thin Crust Pizza, ~220 Calories Per Slice

Thin-crust pizza typically comes in at about 220 calories per slice for a standard 14-inch cheese pizza, cut into 8 slices. Less dough means fewer calories from the base.

The advantage shrinks once you add heavy toppings. A thin-crust meat-lovers slice still contains 400 to 450 calories.

New York Style Pizza, ~285 Calories Per Slice

New York-style pizza has a thinner crust, but the slices are large. Most slices come from an 18-inch pie, which adds more food per slice.

A cheese slice lands near approximately 285 calories. Pepperoni pushes many New York slices toward 400-500 calories.

Regular Crust Chain Pizza, ~290 to 310 Calories Per Slice

Large hand-tossed cheese pizza from major chains usually sits near 290 to 310 calories per slice. This is the most familiar American pizza range.

Pepperoni usually adds 20 to 30 calories per slice at chain portions, but heavier independent pizzerias often add more.

Detroit Style Pizza, ~340 Calories Per Slice

Detroit style pizza has a rectangular shape, thick airy dough, crispy edges, and cheese under the sauce. A single rectangular square of Detroit-style cheese pizza contains approximately 340 calories.

The oil-baked crust and caramelized cheese edges explain the higher count.

Sicilian Pizza, ~390 Calories Per Slice

Sicilian pizza has a thick, soft, focaccia-like crust. That bread-like base adds more calories before toppings enter the math.

A square of Sicilian cheese pizza usually comes in at around 390 calories. Larger bakery-style squares go higher.

Chicago Deep Dish Pizza, ~535 Calories Per Slice

Chicago deep-dish has the highest calorie count because it uses a tall, buttery crust, a deep pan, and heavy cheese layers. The average slice sits near approximately 535 calories.

Some large restaurant slices go much higher. One Lou Malnati’s Chicago Classic Deep Dish Large slice is listed near 730 calories.

How Toppings and Crusts Change the Math

The style figures above use cheese pizza as the base. Toppings, sauce, and crust choice change the final number fast.

How Crust Choice Changes Calories

How Pizza Size Changes the Calorie Count

The same pizza cut into fewer slices gives you more calories per slice. A 14-inch pizza cut into 6 slices has about 33 percent more calories per slice than the same pizza cut into 8 slices.

Frozen Pizza Vs Delivery Vs Homemade: Which Has More Calories?

Frozen, delivery, and homemade pizza all vary by size and recipe. The most accurate method depends on where the pizza came from.

Frozen Vs Delivery Vs Homemade Comparison

Homemade pizza often gives you the most control because you measure the dough, cheese, oil, sauce, and toppings.

How to Find the Actual Calories in Your Pizza

Use the source closest to your pizza.

• For chain delivery, use the brand’s nutrition calculator.
• For frozen pizza, check the nutrition label and serving size.
• For independent pizzerias, estimate by style, crust, and toppings.
• For homemade pizza, weigh each ingredient and search it in USDA FoodData Central.

What About Leftover Pizza?

Leftover pizza has the same calories as fresh pizza. Reheating changes texture, not calories.

Storage still matters because it affects how much you enjoy the slices later. The USDA says refrigerated leftovers last 3 to 4 days. Pizza dries out fast in the original cardboard box. Airtight storage keeps slices in better shape during that window.

Pizza Pack fits this use case because it has a snap-on airtight lid, a built-in vent, and five microwavable divider trays that keep slices separated. It also collapses to save fridge space.
