If you notice an influx of customers ordering your larger pizzas, NPR might have something to do with it. Its report, “74,476 Reasons You Should Always Get The Bigger Pizza,” has gone viral with its pizza math rationale.
According to the Planet Money article, 74,476 prices from 3,678 pizzerias in the U.S. were analyzed on GrubHub. The graph below shows that a 16-inch pizza averages nearly eight cents per square inch, while an eight-inch averages about 17 cents per square inch.
The findings also indicated that it would take four eight-inch pizza (priced at $33) to equal one 16-inch (at $16.59).
Planet money also produced a counterpoint, One Reason To Get Whatever Size Pizza You Want, citing negative marginal returns on pizza. Give it a read.
