How Many Calories Are In One Slice Of Pizza? | Quick Facts Guide

Calories In One Slice Of Pizza By Style And Size

Two levers drive the number: gram weight and fat. A regular-crust cheese slice near 107 g sits around 285 calories based on USDA-derived data. Thicker crusts pack more dough and oil, so totals climb fast.

Typical Cheese Slice Calories By Style (One Slice = 1/8 Of A 12–14″ Pie)

Style	Approx. Slice Weight	Calories
Thin crust, 14″ pie	85–95 g	220–260
Regular crust, 14″ pie	100–115 g	270–320
Deep dish/pan, 12–14″	120–150 g	350–450+

Brand nutrition pages and calculators list slice weights and toppings, which helps you pin a tighter range. A classic cheese profile around 285 calories aligns with USDA-based entries that use lab-sourced data sets.

Once you set your daily calorie needs, it’s easy to fit a slice without guesswork. Size, dough style, cheese type, oil on the pan, and toppings move the needle most.

What Drives Pizza Slice Calories?

Crust Type And Dough Weight

More dough means more carbs and often more oil. Pan styles sit higher due to thicker dough and oil in the pan. Thin crust trims grams per slice, which lowers energy.

Cheese Amount And Type

Cheese brings fat and protein. Part-skim mozzarella yields fewer calories than whole-milk blends. Extra cheese adds fast; a single ounce can tack on 70+ calories.

Sauce And Oil

Tomato sauce is light on energy. Oil brushed on crust or drizzled after baking adds dense calories. A teaspoon of oil adds about 40 calories.

Popular Toppings

Lean meats and vegetables shift totals less than cured meats. Pepperoni and sausage add fat and sodium. Chicken and mushroom keep the range moderate.

How To Estimate Your Slice Without A Label

Use The Baseline, Then Adjust

Start from a common cheese slice at ~285 calories. Go up for thicker crust or extra cheese; go down for thin crust or lighter cheese. Add toppings from the table below to land near the mark you need.

Weigh Or Compare By Size

No scale? Compare to known sizes. A 14″ pie sliced into eight pieces gives a mid-range slice. A jumbo foldable slice from a street shop often weighs 150 g or more and can clear 400 calories.

Cross-Check With A Reputable Database

USDA-based tools list cheese near 285 calories per ~107 g slice and pepperoni near the low 300s at ~111 g. Chain calculators and PDFs list exact builds for their menus, which helps when you’re ordering from a specific brand.

Cheese Slice Benchmarks

Generic cheese at 285 calories per ~107 g is a widely used yardstick. Pepperoni near 313 calories per ~111 g shows the bump from cured meat and extra fat. Deep dish slices can exceed 400 calories without add-ons.

Why Your Local Slice Can Vary

Independent shops use different pans, flour, cheese blends, and slice sizes. Oil on the pan alone can nudge a slice by dozens of calories. Ask for slice size or check if nutrition cards are posted near the counter.

What About Sodium, Carbs, And Protein?

A typical cheese slice carries around 36 g carbs, 12 g protein, and 10–11 g fat. Sodium often lands near 600–700 mg per slice. That’s close to a quarter of the FDA Daily Value for sodium for a single slice, so pace salty toppings and sides. See the FDA page listing the Daily Value amounts for context.

Add-On Calories From Popular Toppings

These are ballpark adds per slice beyond a plain cheese base. Numbers vary by brand and cut size, but the pattern holds across menus.

Approximate Calories Added Per Slice

Topping	Typical Add (Per Slice)	Notes
Pepperoni	25–40	Fatty cut; raises sodium
Sausage	60–90	Higher fat; bigger swing
Grilled chicken	20–35	Lean protein
Extra cheese	60–80	About 1 oz more
Veggies (mushroom, pepper, onion)	5–15	Low energy; adds fiber
Olives	15–25	Some fat and salt
Pineapple	10–20	Small sugar bump

Practical Ways To Fit A Slice Into Your Day

Balance The Rest Of The Plate

Pair a slice with a salad or roasted veg to add volume and fiber. Skip a sugary drink; water or unsweetened tea keeps the meal steady without more calories.

Watch The Add-Ons

Dips and stuffed crust boost fat and carbs. Two cheese slices with soda can cross 600–700 calories before sides, which matters if you’re aiming for weight loss.

Mind Your Sodium

Chain slices often land near 25–30% of the sodium Daily Value. If lunch includes a salty slice, steer the rest of the day toward fresh fruit, yogurt, or beans to keep the day’s total under 2,300 mg.

Smart Ordering Tips

Thin Or Regular Over Pan

Go thin crust to trim gram weight. If the shop brushes oil on the crust, ask them to skip it.

Load Veggies First

Veg toppings add flavor and texture with a small calorie bump. Pick two or three favorites, then add a lean protein if you want more staying power.

Cheese Strategy

Ask for light cheese or half cheese on part of the pie. You still get the melt and stretch with fewer calories.

Make The Math Work For Your Goal

Lunch Plan

One regular-crust cheese slice with a side salad and water lands near 350–400 calories for the meal, depending on dressing. That keeps room for a balanced dinner.

Game Night Plan

Count two slices up front. Choose thin crust, add veg, and keep dips light. Share a big salad at the table to slow the pace.

Weight Loss Plan

Use the baseline numbers to fit slices into a weekly plan. Track averages across days instead of stressing over one night. When you want a treat pie, bank calories earlier in the day by keeping breakfast and lunch lean.

Quick Answers

Is Thin Crust Always Lower?

Usually, yes, due to less dough and oil. Thick cuts or extra cheese can erase the gap, so check the slice size.

Does Reheating Change Calories?

No. Water loss may crisp the slice, but energy stays about the same.

Best Way To Estimate At A Party?

Glance at the pie size and cut. If slices are small squares from a sheet pan, treat two squares as one regular slice in your tally.
