Why Bigger Pizzas Are Usually a Better Deal

Pizza area grows with the square of the radius, so a modest increase in diameter creates a much bigger pizza. This calculator finds each pizza's area (pi times radius squared) and divides the price by that area to show the true cost per square inch.

How to Use the Result

The option with the lower price per square inch gives you more pizza for your money, even if its total price looks higher at first glance.
