You shouldn't be surprised to find out that the bigger the pizza you buy, the less it costs per square inch. You know, economies of scale and all: the price per unit usually decreases the more of those units you buy. What should surprise you, however, is how big that difference really is.
GrubHub/Seamless recently teamed up with NPR to showcase the value per square inch of pizza at different pie circumferences. The snapshot below is part of an interactive chart from NPR that is based on 74,476 prices from 3,678 pizza places around the country.
It turns out that by saving calories and purchasing the smallest pizza on the menu, you are only doing your waistline, not your wallet a favor. And the bigger the pizza is, the more quickly that difference adds up.
The math behind the madness is relatively simple. As a pizza is a circle; the size expands in proportion to its radius. That makes a 16-inch pizza is actually four times as big as an 8-inch pizza, not twice as big.
If you think about that in terms of price, you'll realize that for the same amount of pizza, you'd have to pay about twice as much if you purchased four 8" pizzas instead of one 16" pizza.
Are all of your poor pizza decisions flashing before your eyes yet?
And the trend holds true across the board. Out of the thousands of pizza prices nationwide, every time you buy a bigger pizza, you are getting a much, much better deal.
So next time you have a hankering for a slice, don't limit yourself. Invite a group of friends instead and go all in for the large. What you don't eat can always go home with you. We all know that pizza is the ultimate leftover food anyways.
