A 7-inch pizza measures 7 inches (about 18 cm) across and has roughly 38.5 square inches of pizza. That makes it a personal-size pizza: a light meal for one adult or a full meal for one child. Most 7-inch pizzas are cut into 4 slices.

Pizza size always refers to the diameter, the distance straight across the pizza through its center. The amount of pizza you actually get is the area, which you can work out with π × radius². For a 7-inch pizza that is 3.1416 × 3.5 × 3.5 = 38.5 square inches.
How Big Is It in Real Life?
It fits comfortably on a standard 10 to 11-inch dinner plate with a couple of inches to spare. It is about the size of a small side plate. In restaurants you will usually find this size sold as a personal pizza, on kids’ menus, or as a single-serve frozen pizza.
Is a 7-Inch Pizza Small?
Yes. It is the smallest size most pizzerias sell, with about half the pizza of a 10-inch small (78.5 sq in) and only about a third of a 12-inch medium (113 sq in). If you are hungry, or ordering for more than one person, this size will not be enough on its own.
Are Two 7-Inch Pizzas the Same as a 14-Inch Pizza?
No, and it is not even close. Doubling the diameter of a pizza gives you four times as much pizza, because area grows with the square of the diameter.
- One 7-inch: 38.5 sq in
- Two 7-inches: 77 sq in
- One 14-inch pizza: 153.9 sq in, the same as four 7-inches
Here is how many of these personal pizzas it takes to match other common sizes:
| Pizza size | Area | Equal to this many 7-inch pizzas |
|---|---|---|
| 10-inch | 78.5 sq in | 2.0 |
| 12-inch | 113.1 sq in | 2.9 |
| 14-inch | 153.9 sq in | 4.0 |
| 16-inch | 201.1 sq in | 5.2 |
| 18-inch | 254.5 sq in | 6.6 |

How Many Slices Are in a 7-Inch Pizza?
It is normally cut into 4 slices of about 9.6 square inches each. Cutting it into 6 makes smaller, easier-to-hold pieces for children or for sharing as a snack, but the total amount of pizza stays the same.
Who Is This Size Right For?
- One person eating lightly, or alongside a salad or side.
- Children: it is a full meal for most kids under 10.
- Trying several flavors: two or three personal pizzas let a couple taste different toppings.
- Portion control: one personal pizza is a fixed, predictable serving.
For a party, order bigger pizzas instead. Our Pizza Party Calculator works out how many you need, and the Kids Pizza Party Calculator adjusts for children’s ages.
How Many Calories Does It Have?
A cheese pizza this size with a regular hand-tossed crust has roughly 570 calories in total, or about 140 calories per slice when cut into 4. This is an estimate scaled by area from typical cheese pizza values using our Pizza Nutrition Calculator. A thin crust or vegetable toppings bring it down; extra cheese, meat toppings or a thick or stuffed crust push it up. For an exact figure, check the label on a packaged pizza or the restaurant’s published nutrition information. For generic ingredient values, USDA FoodData Central is the most reliable free source.
Is It Good Value?
Usually not. Small pizzas cost the most per square inch. For example, a personal pizza at $7 works out to about 18 cents per square inch, while a 14-inch pizza at $15 costs under 10 cents per square inch and gives you four times as much pizza. If you are buying for two or more people, a larger size is almost always cheaper. Compare real menu prices with our Pizza Size & Price Calculator.
Making One at Home
You need about 120 g of dough for a New York-style crust (less for a thin crust). Stretch it to 7 inches, add a light layer of sauce and cheese so the center cooks through, and bake on a preheated stone, steel or tray at your oven’s hottest setting. Small pizzas cook quickly, so start checking after about 8 minutes. The Pizza Dough Calculator gives exact flour, water, salt and yeast amounts for any number of 7-inch pizzas.
