A 24 inch pizza is one of the largest pizzas you’ll find at specialty pizzerias. Often called a giant, XXL, or party pizza, it’s designed to feed a crowd rather than a single family. While most national pizza chains stop at 16 or 18 inches, many local pizza restaurants offer 24 inch pizzas for parties, office lunches, sporting events, and large gatherings.
If you’re wondering how many slices a 24 inch pizza has, how many people it serves, or how it compares to smaller pizzas, this guide explains everything you need to know. The measurements below are based on standard pizza geometry and common serving practices. Actual slice counts and calorie totals may vary depending on the restaurant, crust style, and toppings.

How Many Slices Are in a 24 Inch Pizza?
Most restaurants cut a 24 inch pizza into 16 slices, although some pizzerias offer 20 or 24 smaller party slices.
| Cut Style | Number of Slices |
|---|---|
| Standard Cut | 16 slices |

A 16-slice cut is the most common because it creates slices that are easy to hold while still providing generous portions.
How Many People Does a 24 Inch Pizza Feed?
A 24 inch pizza typically serves 8 to 12 people, depending on appetite and whether other food is served.
A general serving guide is:
- 6–8 people: Large meal with generous portions.
- 8–10 people: Comfortable dinner with 2 slices each.
- 10–12 people: Light meal when served with salad, wings, or appetizers.
For parties where pizza is the main dish, caterers usually recommend planning for 2 to 3 slices per adult.
How Big Is a 24 Inch Pizza Compared to Other Sizes?
Pizza size increases dramatically because surface area grows much faster than diameter.

How Much Does a 24 Inch Pizza Weigh?
The weight depends on the dough, crust thickness, cheese, and toppings.
Typical weight ranges include:
- Thin crust: 60–80 ounces (1.7–2.3 kg)
- Hand-tossed crust: 75–100 ounces (2.1–2.8 kg)
- Thick crust or pan style: 95–130 ounces (2.7–3.7 kg)
Heavy toppings such as extra cheese, sausage, bacon, or multiple meats can significantly increase the total weight.

Calories vary by recipe, crust, and toppings.
For a standard cheese pizza:

Specialty pizzas with stuffed crust or extra cheese may exceed these estimates.

Is a 24 Inch Pizza Enough for a Party?
Absolutely.
A 24 inch pizza is specifically designed for large gatherings. It can comfortably feed a group of friends, coworkers, or family members, especially when paired with appetizers, salads, or desserts.
For very large events, offering multiple giant pizzas with different toppings gives guests more variety while ensuring everyone has enough to eat.
Best Occasions for a 24 Inch Pizza
A 24 inch pizza is ideal for events where you’re feeding a crowd.
Popular occasions include:
- Birthday parties
- Office lunches
- Graduation celebrations
- Sports watch parties
- Family reunions
- School events
Because one giant pizza replaces several smaller pizzas, it can simplify serving and reduce packaging waste.
Tips for Choosing the Right Pizza Size
Before ordering, estimate how many slices each guest is likely to eat.
If pizza is the only meal, plan on 2 to 3 slices per adult. If you’re serving wings, salads, breadsticks, or desserts, one large pizza can feed even more people.
For groups larger than 12 adults, consider ordering two giant pizzas with different toppings to provide both variety and enough food.
