How Much Bigger Is a 12 Inch Pizza Than a 10 Inch?

A 10 inch pizza may seem 2 inches smaller than a 12 inch, but the difference in pizza is big.
A 10 inch pizza has a total area of about 78.5 square inches. Compared to a 12 inch pizza with 113 square inches, and you’re getting around 44% more pizza with a 2 inch increase in diameter.
This is because pizza area increases with the square of the radius, a math concept that means small changes in diameter make difference in pizza.
How Much Bigger Is a 12 Inch Pizza Compared to Other Pizzas?

Let’s look at how a 12 inch pizza compares to the other common pizza sizes. This is helpful when you’re trying to figure out what to order for different situations.
12 Inch Pizza vs 10 Inch Pizza

As we just saw:
- 12 inch pizza: 113 square inches, 8 slices, feeds 2-3 people
- 10 inch pizza: 78.5 square inches, 6 slices, feeds 1-2 people
- The difference: 34.5 square inches (44% more pizza!)
If you’re ordering for date night, a 10 inch is enough if you’re light eaters or have appetizers. But for a hungry couple, the 12 inch is the better value, you get nearly half as much pizza for a few more dollars.
12 Inch vs 14 Inch Pizza

Now let’s go big:
- 12 inch pizza: 113 square inches, 8 slices, feeds 2-3 people
- 14 inch pizza: 154 square inches, almost 10 slices, feeds 3-4 people
- The difference: 41 square inches (36% more pizza with the 14 inch)
When Consumer Reports analyzed pizza pricing, they found that going from a 12 inch to a 14 inch costs around 25% more but gives you 36% more food.
The 14 inch is great for a family of 3 and 4 or for when you want leftovers. If you’re hosting a small gathering, I’d definitely go with the 14 inch over the 12 inch.
12 Inch Pizza vs 16 Inch Pizza

The 16 inch pizza is considered an “extra large” or “family size”:
- 12 inch pizza: 113 square inches, 8 slices, feeds 2-3 people
- 16 inch pizza: 201 square inches, 12 slices, feeds 4-6 people
- The difference: 88 square inches (78% more pizza!)
This is almost double the amount of pizza. A 16 inch costs around $5-8 more than a 12 inch, but you’re getting twice as much food.
I’ve found that a 16 inch pizza is perfect for game nights or when you have 4+ people. It’s also great when you want leftovers for the next day.
