Are you ready for a mindblowing revelation?

If you're splitting pizza with friends, you'll technically get more bang for your buck by splitting one 18-inch pizza instead of ordering two 12-inch pizzas.

It sounds counterintuitive, but Fermat's Library did the math: An 18-inch pizza has 254 square inches of "pizza," while two 12-inch pizzas only have about 226 square inches.

Here's a useful counterintuitive fact: one 18 inch pizza has more 'pizza' than two 12 inch pizzas pic.twitter.com/hePSpG0pJs — Fermat's Library (@fermatslibrary) January 7, 2019

People were understandably confused — isn't two more than one?

So the best option is to get two 18 inch pizzas then. Got it. — Elaine Ferguson (@fergusonelaine) January 7, 2019

Others found flaws in the math: If you like crust, this logic doesn't make sense. If you're getting a stuffed crust, then definitely go for two pizzas.

Yeah, but the crust is arguably the best part and two 12 inch pizzas have 33.3% more crust than a 18 inch pizza. And now I'm hungry, thanks @fermatslibrary! pic.twitter.com/ZUfGicpcWG — Tamás Görbe 🇭🇺🇬🇧🇪🇺 (@TamasGorbe) January 7, 2019

But if you just want to get ahead of the Great Pizza Conspiracy and have more cheesy goodness, then just opt for one large pie. Your wallet (and stomach) will thank you.
