Standard Pizza Size

Revision as of 10:54, 13 October 2011

ISO 216 defines paper sizes. B0, A0, B1, A1, B2, A2, etc...

So how about matching pizza sizes?

Should they match the paper sizes - ie, be of equal area to A4/A3/etc paper sizes?

or

Should one key dimension of the pizza (either circumference or radius) be a nice metric round number? (radius=1m means a pizza with pi m² area!)

"ideal" A and B series paper sizes would be the following: B3 is 1767.76 cm² A3 is 1250 cm² B4 is 883.88 cm² A4 is 625 cm²

A "Pizza with area of A0" - let's call that a "P-A0" would be a pizza of surface area of 1m!

Let's start with a radius of 50cm (since this is a nice conceptual diameter of 1m) ...and then reduce radius by half for each size in the series?
