Forum / Pizza oven chimney

Hi, I am constructing a pizza oven in our garden. While there is plenty of information on the Web about what size and height to build the oven, I can't find anything about what height and diameter I need for the chimney. Is there a formula, like oven volume to chimney diameter? 

Any help will be much appreciated,

5:1 is the correct formula
