Why Compare Pizza by Price per Square Inch?
Pizza menus price by diameter, but what you actually eat is area, and area grows with the square of the diameter. A 16″ pizza is only 4 inches wider than a 12″ pizza, yet it has almost 78% more pizza. That is why the bigger size is usually the better deal even when it looks expensive. This calculator turns each menu price into a price per square inch, applies any coupon, and can ignore the crust so you compare only the toppable area. In seconds you can see which size gives you the most pizza for your money.
How the Pizza Size & Price Calculator Works
- Enter the diameter (inches) and price of each size you are considering.
- Add a coupon % to any size that has a discount.
- Optionally tick Don’t count the crust and set the crust width to compare only the toppable area.
- Use + Add Size to compare up to 6 sizes, then press Compare.
- The table shows each size’s area (π × radius²) and price per square inch. The lowest price per in² is the best value.
Example: a 12″ pizza at $12 has 113 in² of pizza ($0.106 per in²). A 16″ pizza at $18 has 201 in² ($0.090 per in²), so the 16″ is about 16% cheaper for the same amount of pizza.
Pizza Size & Price Calculator FAQs
How do you calculate the area of a pizza?
Area = π × radius². Halve the diameter to get the radius, square it, then multiply by 3.1416. A 12″ pizza has a 6″ radius, so its area is 3.1416 × 36 ≈ 113 square inches.
Is a large pizza always better value than a medium?
Usually, because area grows faster than price. A 14″ pizza (154 in²) has about 36% more pizza than a 12″ (113 in²) but rarely costs 36% more. Always check with real menu prices, especially when coupons apply to smaller sizes.
Are two medium pizzas more than one large?
It depends on the sizes. Two 12″ pizzas (226 in²) have more pizza than one 16″ (201 in²), but less than one 18″ (254 in²). Use the Pizza Area Calculator to compare any combination.
Should I count the crust when comparing pizza value?
If your group leaves the crust, exclude it. On small pizzas the crust is a larger share of the total area, so excluding it makes larger sizes look even better value.
What is a good price per square inch for pizza?
There is no fixed benchmark because prices vary by region and pizzeria. As a reference, a 14″ pizza at $15 works out to about 10 cents per square inch. Compare sizes at the same shop rather than across very different styles.
