good point about bottom margin. I had never thought that through.
on having all books be consistent, i once upon a time decided I wanted a 0.3em space between paragraphs and reworked a few hundred books...
a couple of e-reader device changes later I decided that actually I liked 0.1em better...
2nd redo
move on a year and I am thinking, actually, no space at all between paragraphs is what I like best....
whenever I dream of doing another global consistency project, I have to remind myself of that history
I think the devices you choose to read on play a big part in the aesthetic of making a book look " just right" on screen
0.3 looked ok on a basic Sony PRS, but as my devices got bigger, and my eyesight got poorer, it became more about minimizing page turns, for comfort.
So I began to shrink side margins, slash away top space above chapter headers, lose the between-paragraph spaces ... all of which could well horrify some other reader.
But I tweak copies books exclusively for my own reading, so no one else has to like my layout choices
