One of the many pizza mysteries. Why are the boxes always square if the pizza is round?
Like most things, it really all comes down to cost saving. It is much cheaper to mass produce square boxes than round ones since a square box can be made from a single sheet of cardboard. The square boxes are also much easier to stack and store since they can remain flat until their used.
There is also a theory out there that the square shape keeps the heat inside the box better? I’m not sure if I buy that one though.
