I've seen a couple of comments about converting files to PDF for the iLiad -- not having one myself (yet) it's probably too soon to really worry about it, but I'd like to make Project Gutenberg's titles available pre-formatted for those that aren't as handy with the various tools as most MobileReader users are...
Which leaves me trying to guess what size might work best;
13x17cm
Margins: left and right 0.2cm
top and bottom: 0.5cm
A5 (148x210mm)
Margins: left and right 0mm
top: 15mm
bottom: 0mm
And I've created a few that look OK on my computer screen at
A5
Margins: left, right, bottom 5mm
top: 10mm

I'd welcome suggestions and feedback on the current set up --
manybooks will have "iRex iLiad" as a download option for a few days.
