Pizza Size Value Calculator
Which pizza is better value per square inch. Area grows with the square of the diameter, so a 16 inch pizza is not a third bigger than a 12 inch one, it is nearly twice the size.
Also called: pizza size comparison, price per square inch.
Pizza B is better value. Pizza A is $3.54 per square inch and B is $2.98. B has 1.78x the area of A for 1.5x the price.
How this is calculated
Doubling a diameter quadruples the area. That is why the large is almost always better value: the price rises roughly linearly with diameter while the food rises with its square. Two 12 inch pizzas have less area than one 16 inch, which surprises most people and is the single most useful fact on this page.
