Potential Sizes for the Catalogue and guide

I started thinking about the sizes of both the catalogue and the guide, after looking at the dimensions and the regulations set out by the royal mail I went about deciding what size I wanted both of my pieces of print. As the guide is potentially going to be something that the cyclists take with them on there journey it needs to be small and compact but contain all the relevant and useful information for them to use. I had the idea of the guide being a similar size to an ordinance survey map so that it could be stored with the maps in the panniers or a side bag. 


Catalogue: 247mm x 190mm
Guide: 220mm x 130mm
