Order the largest

Maybe I need to create a new blog category “pizza.”  Anyway, loved this Planet Money post on the economics of ordering pizza.  Through a systematic examination, they determined what I long ago figured out anecodtally.  The bigger size is almost always a better deal.  In fact, I’ve been known to do more than a few pi r squared calculations in my head when ordering pizza.  Planet Money:

The math of why bigger pizzas are such a good deal is simple: A pizza is a circle, and the area of a circle increases with the square of the radius.

So, for example, a 16-inch pizza is actually four times as big as an 8-inch pizza.

And when you look at thousands of pizza prices from around the U.S., you see that you almost always get a much, much better deal when you buy a bigger pizza.

As I told my friend who sent me the link, the best part is that not only do you save money, but more pizza = more pizza.
