When I first started to look for what Plotter to get I landed on the A5, just because that is what I always do.

Then this summer I started to think differently, and big ass process on sizes started.

How I usually go about things like this is to see what I am using, and how much I can decrease size before it is a problem or if increasing makes anything better.

Based on how I use the pages in my full sized Travelers Notebook, something with the width of the Mini 5 and height for Bible/Regular would most likely be the ideal. But the difference between them are not that large, there are however times, like with small slings etc where narrow notebooks make things easier.
