Welcome to WhatSize

Have you ever wondered how much pizza you should order, or how you’d get the best value for your money? 

Did you know, for example, that a 14 inch pizza contains almost three times as much pizza as an 8 inch pizza? In this case, it’d be better for two people to order a ‘half and half’ 14 inch pizza, rather than an 8 inch pizza each – if the price was right of course.

Bigger is usually better. This is especially true when it comes to pizza. 

Quick size comparison

12 inch = 2 x 8 inch
18 inch = 2 x 12 inch

20 inch = 2 x 14 inch
20 inch = 4 x 10 inch
