Two Large Pizzas vs. Three Medium Pizzas: Which is a Better Deal?

by Michael on January 5, 2013 · 0 comments

While ordering pizza for dinner tonight, I got to wondering… Which gives you more, two large pizzas or three medium pizzas? Fortunately, I’ve had sixth grade math so I was able to dust off a bit of that knowledge to figure out the answer.


The answer, of course, depends on the actual size of the pizza. But once you know the diameter (and hence the radius, r) you can calculate the area of the pizza:

area = πr2

So… A standard Domino’s or Papa John’s large (14 inch) pizza covers:

area = 3.14 x (7 x 7) = 153.9 square inches

And a standard medium (12 inch) pizza covers:

area = 3.14 x (6 x 6) = 113.0 square inches

So two large pizzas is just under 308 square inches, whereas three medium pizzas is 339 square inches — three mediums are about 10% larger.

As for which is a better deal… The right answer depends on pricing, of course.

Bonus points: An extra large (16 inch) pizza covers roughly 201 square inches.
