Why area beats diameter

Pizza area grows with the square of the diameter, so a 16 inch pizza is not one third bigger than a 12 inch, it is 78 percent bigger. Comparing price per square inch is the only fair way to judge, and larger pizzas win surprisingly often.

The crust caveat

Price per square inch assumes you value the whole pizza equally. If your group leaves crusts, thick crust styles shift the math toward whoever wastes less, but for standard pizzas the area comparison holds.

Pizza Value Compare FAQs

Is a large pizza a better deal than a medium?
Usually yes. A 16 inch pizza has 78 percent more area than a 12 inch, so unless the large costs 78 percent more, it wins on price per square inch.
How do you calculate pizza area?
Pi times radius squared. A 12 inch pizza: 3.1416 x 36 = 113 square inches. Divide the price by that for the per square inch cost.
Are two mediums better than one large?
Rarely. Two 12 inch pizzas give 226 square inches versus 201 for one 16 inch, but they usually cost much more than one large.
Does topping coverage change the value?
Only if one size is skimped. The math assumes similar topping density; a loaded medium can beat a sparse large in eating value if not in raw area.
What about square or rectangular pizzas?
Area is area: length times width. A 12x18 inch sheet pizza is 216 square inches, comparable to a 16 inch round, so compare per square inch the same way.
