Let's assume you have it 8.5" × 11", with 1" margins, so the actual text block is 6.5" × 9"... with which font size? say it's around 12pt. Now this has to fit in a screen that, for a typical 6" reader, is around 3.6" × 4.8". Even if the reader could trim the margins and scale everything perfectly, it would be an almost 50% reduction, so the actual font size in the reader will be something like 7pt, which is probably too small, worse yet if you used some small type in your book.
If you format the book for 3.6" × 4.8" page size with 0.1" margins, still with 12pt font size, a 6" reader will happily display it in its original size or very slightly reduced, so the font will remain ~12pt. In a 5" reader, it could be shown at ~10pt, which is still fine.
Of course, you could also format the book for 8.5" × 11" pages, with 28pt font size, and it would look OK in a 6" screen. Or you could just scale down your 8.5" × 11", 12pt PDF to 3.6" × 4.8", and it would be pretty useless.
