Hello!

I'm wanting to get out of my comfort zone and bind a slightly bigger format. My usual one is A5, but now I'm wanting to size up to an A4 bind (It will be a thicker one too, with my font size at 14). Since setting up the document for my typeset I immediately came across a problem: I'm unsure about the "correct" margins since my usual ones will just look dumb and I don't have fiction books that size to use as reference. Is there a secret formula to calculate margins so they'll look pleasing? I've googled around and now I'm just more confused than ever, though I'm especially unsure about the gutter and how much will be necessary (I do plan the book to open relatively flat)

All help is appreciated :)
