As a person who formats ebooks myself on BD,I can say on Sony LRF files, the margins can be set manually anywhere from 0 to .what.. 55pt?
It becomes obvious that books with a too small margin are less pleasant to read.
Also books with a larger margin (like Sony Store LRF books),read more pleasant, but take more pageswaps,and hold only very little data (text) per page.
Generally people set a margin ranging from 10 to 25pt, which is about the same margin as 4 to 7 letters: (on average the size of the margin):
|10|
|15pt|
|20 pt|
Not that large...
Sony store uses something like 25- 35pt? (anyone knows?)
