How to use the pizza value comparator

  1. Add the optionsEnter each size or deal from the menu, with its diameter or width and length.
  2. Enter pricesType the price and, for deals, the number of pizzas.
  3. Find the winnerThe best value is ranked first, with how much more the others cost for the same area.

Why the biggest pizza is usually the best deal

Pizza area grows with the square of the diameter. An 18-inch pizza has about 254 square inches, more than twice the 113 square inches of a 12-inch pizza, but it rarely costs twice as much. That's why comparing price per square inch is the fairest way to judge value. It also shows that one 18-inch pizza has more food than two 12-inch pizzas (226 square inches), a comparison that surprises many people. For rectangular pizzas, the area is width × length. The calculator counts the whole pizza, including the crust. Thick crust edges and toppings still differ between restaurants.

The crust question

Bigger pizzas also have a smaller share of crust. If you prefer toppings over crust, the large pizza wins by even more.

Leftovers

The best value only counts if you'll eat it. Cold pizza is fine, but wasted pizza isn't a bargain.

Pizza Value Comparator FAQ

How do I calculate a pizza's area?

For a round pizza, π × (diameter ÷ 2)². For a rectangular one, width × length.

Why use price per square inch?

It compares different sizes fairly, because it measures how much pizza each dollar buys.

Can I compare metric sizes?
