A standard slice of pizzeria pizza contains 250–350 calories for a regular-crust cheese slice cut from a 14-inch pie. That range widens considerably depending on crust type, toppings, cheese quantity and slice size — a deep-dish pepperoni slice can exceed 500 calories, while a thin-crust margherita slice may be as low as 200 calories. This guide breaks down the calories in pizzeria pizza by every variable that matters so you always know what you are actually eating.

Quick reference — pizzeria pizza calories per slice:
Thin crust cheese: ~200–250 kcal · Regular crust cheese: ~250–300 kcal · NY-style slice: ~300–400 kcal · Deep-dish: ~400–500 kcal · Pepperoni adds ~30–50 kcal per slice

Pizzeria pizza calories by crust type

Thin crust pizza: 200–280 calories per slice. Regular crust pizza: 250–350 calories per slice. Thick crust or pan pizza: 300–400 calories per slice. Deep-dish pizza: 350–500 calories per slice. All figures are for a cheese slice from a standard 14-inch pie cut into 8 slices:

The difference between a thin crust and deep-dish slice can be 200–300 calories — entirely from the crust itself. A thin crust slice at 220 calories versus a deep-dish at 480 calories represents a 260-calorie gap before any toppings are considered.

How toppings change the calorie count

Each topping adds calories on top of the base cheese slice figure. Here is the approximate calorie addition per topping per slice of a standard 14-inch pizza:

Calories by pizza size

Pizza size determines slice size — a slice from a 10-inch pie is significantly smaller than a slice from an 18-inch NY-style pie cut into the same number of pieces. Here is how a regular-crust cheese pizza scales by diameter:

A whole 14-inch cheese pizza contains approximately 2,000–2,400 calories — roughly the entire daily calorie budget for many adults. This is why knowing your personal calorie target before ordering makes a meaningful difference. Use our BMR calculator and TDEE calculator to find your number.

Calories at major pizza chains

Costco’s 710-calorie cheese slice stands out — it is 2–3× the calories of a standard chain pizza slice because Costco slices are cut from an 18-inch pizza and are roughly twice the weight of a typical chain slice.

How to eat pizza while tracking calories

• Choose thin crust: Thin crust pizza: 200–280 calories per slice — less dough and fewer carbohydrates lower the calorie count. Switching from pan to thin crust saves 80–150 calories per slice without changing the toppings or flavour profile.
• Load up on vegetable toppings: Adding mushrooms, peppers, spinach and onions adds 5–15 calories per slice while significantly increasing meal satisfaction and nutrient density. Replacing pepperoni with vegetables saves 30–50 calories per slice.
• Skip extra cheese: Extra cheese is one of the highest-calorie additions at 40–70 kcal per slice. The standard cheese amount on most pizzeria pies is already generous.
• Know your slice count before ordering: Decide how many slices fit in your daily calorie budget before the pizza arrives — not after. It is significantly easier to stick to a plan you set before eating than to moderate once you have started.
• Snap and log immediately: Pizza is one of the most underestimated foods in calorie counting because slice size varies so much between pizzerias. Snap your slice with Tou Calo before eating for an instant AI estimate based on the actual size and toppings visible in the photo.

Calories in pizzeria pizza — FAQ

How many calories are in a slice of pizzeria pizza?

A standard pizzeria pizza slice with regular crust contains 250 to 350 calories depending on toppings. Thin crust cheese slices run 200–250 calories. NY-style slices from larger pies run 300–400 calories. Deep-dish slices can exceed 500 calories. The most important variables are crust thickness, slice size and topping choice — each can shift the calorie count by 100–200 calories per slice.

How many calories in 2 slices of pizzeria pizza?

Two regular-crust cheese slices from a standard 14-inch pizza contain approximately 500–600 calories. Two thin-crust vegetable slices may be as low as 400–450 calories. Two pepperoni slices from a pan pizza can reach 700–800 calories. Two slices is the most common single sitting portion for adults — knowing your daily calorie target from our TDEE calculator helps you plan what the rest of the day’s meals should look like after eating pizza.

What is the lowest calorie pizza at a pizzeria?

The lowest calorie option at most pizzerias is a thin-crust pizza with vegetable toppings and standard cheese. A thin-crust margherita or vegetable slice typically runs 200–230 calories per slice. Requesting light cheese saves a further 30–50 calories per slice. Among chain options, thin crust pizza at 200–280 calories per slice is the lowest calorie style available.

How many slices of pizza can I eat on a diet?

It depends on your daily calorie target, which is determined by your TDEE and deficit goal. For someone on a 1,600-calorie diet, two regular-crust cheese slices (approximately 560 calories) represent 35% of the day’s budget — leaving 1,040 calories for other meals, which is workable if those meals are lighter. Two thin-crust vegetable slices at approximately 440 calories represent 27% — more flexible. Use our calorie deficit calculator to find your personal daily number first.

Why does pizzeria pizza have more calories than frozen pizza?

Pizzeria pizza is typically higher in calories than comparable frozen pizza for three reasons: larger slice sizes, more generous cheese portions and a higher oil content in the dough and sauce. Frozen pizza is manufactured to standardised portion sizes with controlled ingredient amounts. A pizzeria slice is cut by hand from a freshly made pie where cheese and topping quantities vary significantly — often more generous than a frozen equivalent of nominally the same type.
