Did we solve your problem today?

A bigger pizza usually beats two small ones — compare by area, not diameter.

The math behind it

Area = π × radius². Doubling the diameter quadruples the pizza, so price per in² reveals the real deal.

14 in → 154 in². An 18 in is 254 in² — 65% more pizza.

Why compare per in²?

Because area, not diameter, is what you actually eat.
