Knowing that PDF is not a suitable eBook format, for some reasons I'm still trying to adopt it as my main format. So, my question is, what's the suitable page size for displaying on a 7" devices like the Galaxy Tab or NookCOLOR...?

Cheers.

Edit: To answer my own question, I'm using 90 x 150mm, 10/11 font size, 1.25/1.50 line spacing, and 10-15mm margins on manybooks.net

But these are preliminary numbers, need to get my hands on a real device to determine the optimal numbers.

Edit 2: To maximize the screen usage, it seems a better idea to put the blank space/margins outside the normally viewable area, and only show them when needed (e.g. making annotations), so the paper size could be 120 x 180mm with 15mm margins. With ezPDF on Android you can use the "Fitting to Text Column" feature to maximize the viewing area.

Edit 3: And one may want to increase the margins for technical books which making annotations are more likely. Although a 7" screen is probably not optimal for reading such anyway. A 10" screen seems more suitable...

Preparing the files for a 7" screen using Word, the page size could be 120 x 180 with 15mm margins, 12pt font size, 1.15 spacing. It's also possible to specify a background colour but normally Word doesn't print it, have to go into Options and change the settings.
