Well, I accept that, Carradee. I just don't know. I'm looking at a hardback edition of Catch-22, and though I don't mind the tight spacing between the lines, I'm put off by the .5" margins. To me, that just seems odd to go to the edge of the page like that.
Anyway, I just tried resetting my work to 11pt on 13pt, and it just appeared too spacious. Maybe it's simply a matter of what one is accustomed to. I only ask because I've had a complaint that, as you say, it's hard on the eyes. My eyes are shot anyway, so perhaps I don't know.
Thanks and kind regards,
Jack
