You should always order the bigger
pizza. While an 8“ pizza is roughly
50 square inches, a 16” pizza is 200
square inches, which is 4 times
bigger but most pizza places charge
by radius and don’t consider the
overall area of the pizza. An NPR study
found that one 20” pizza is actually
bigger than two 14” pizzas, but is
also, on average, $9.00 cheaper. Source

Okay, but this is actually really useful for university students.  Every cent counts, and if you have a minifridge (hell, even if you don’t, wrap it up tightly in foil while it’s still warm and you can just keep it out at room temp for a couple days and it’ll be fine) the inevitable leftovers won’t be a problem.
