Page margins in 6"x 9" books
I've published several books, but it takes me so long to write them that by the time I'm ready to publish, I seem to run into new problems with templates.
This time I have copied an A4 document into the 6"x9" template and the margins are huge. Is there a required or recommended margin and should the margin on the left be bigger because it will be close to the book binding? (Book has 345 pages if I give it 0.5" margins all round and 11 point font.)
