I'm very new to book layout—basically I need to produce books individually for myself and friends and I want them to look nice so I'm trying to learn how to do that. There's lots of helpful information online about canons, so I'm currently using Tchichold's Canon to lay out a book and to create a template.
The thing I can't find anywhere online is advice about placing page numbers, headers, and footers. Horizontal placement is of course no problem—"flush right," "flush left," and "center" are all very specific. But other than "below/above the margin," are there any principles that guide aesthetically pleasing vertical placement of these elements, either within the canons or otherwise? If so, what are they?
And—in case the answer to the above question is "no"—my more specific question: the book I'm currently working on (using Tchichold's Canon) is 6" by 9", with margins of 1" (top), 2" (bottom), .666" (inner), and 1.333" (outer). What would aesthetically pleasing placements be of page numbers, headers, and footers?
(In case it matters, I'm using Affinity Publisher.)
Thanks in advance for any help you're able to give!
