The printed book has reasonable margins; there's over an inch of space on both sides of the book. The text is small but to my eyes looks like 12 or 13pt font (caps characters are around 2.5mm high). By way of comparison, the text is around the same as Leslie Lamport's LaTeX book and slightly larger than Donald Knuth's TeX book - though the latter has more dense text as the line spacing is reduced. So yes, it's a dense book, but it's not particularly unusual for a technical book, and the 1" margin is sufficient for small annotations.
