Pizza Size Value Calculator
Is a large pizza really a better deal than two mediums? This calculator settles the age-old debate by comparing pizzas based on actual area and price per square unit. Enter the dimensions and prices of any pizzas you're considering, and instantly see which offers more pizza and which is the better value. Works with both round and rectangular pizzas, and handles any units you prefer.

How We Calculate This
For round pizzas: Area = π × (diameter/2)². For rectangular: Area = length × width. Cost efficiency = total price / total area. The pizza with lower cost per unit area is the better value.
Frequently Asked Questions
Why is the large pizza usually a better deal?
Pizza area grows with the square of the diameter. Doubling the diameter quadruples the area. So an 18-inch pizza has 2.25 times more pizza than a 12-inch, but rarely costs 2.25 times more. This is why larger pizzas typically offer better value per square inch.
Does this account for crust thickness?
This calculator compares surface area only. If one pizza has significantly thicker crust or more toppings, that's not captured here. Consider it a comparison of pizza real estate, not total volume.
What about the crust-to-topping ratio?
Larger pizzas typically have a better topping-to-crust ratio because the crust edge is a constant width while the center area grows. A larger pizza means proportionally more topped surface.
Can I compare more than two pizzas?
Currently this calculator compares two options at a time. To compare three or more, run multiple comparisons and note the cost per square inch for each to find your overall best deal.
