How to compare pizza value
Enter diameter and price for two pizzas.
1
Enter pizza sizes
Use the advertised diameter.
2
Enter prices
Use the menu price including tax if possible.
3
Compare area
The lower price per square inch is better value, all else equal.
What does this tool do?
A larger pizza is usually better value because area grows with the square of the diameter. This calculator compares two pizzas by area and price per square inch, so the cheaper-looking option is not always the cheaper meal.
The Formula
Area = π × (Diameter ÷ 2)²; Value = Price ÷ AreaFrequently Asked Questions
Is a 16-inch pizza twice a 12-inch pizza?
No. Area scales with the square of diameter: a 16-inch pizza is about 78% larger than a 12-inch one, not 33%.
Does this account for toppings?
No. It compares base area and price; topping quality and quantity are not included.
