Inspired by the question Vertical spacing, pagination and ideal results I started to wonder what are the priorities for typographical rules (/norms).

For example, which is worse: an orphan, or a widow?
How about ragged bottom, or orphan?

Does such a priority list exist?

Knuth introduced the notion of badness in his typesetting algorithms, well knowing that one cannot achieve perfection in typography, but rather both the algorithms and the author should strive to minimize badness. So here is my interpretation of an overall badness!

  1. Overful boxes This should be considered almost a cardinal sin. If you have code or words sticking out in the margin give yourself a badness of a 300.
  2. Fonts If you are using more than three different fonts in your pages, give yourself a badness of a 100. If you are using the standard class headings give yourself a badness of 50.
  3. Too much or too little grayness Too much leading, too heavy or too light fonts, over emphasizing words with bold and rainbow colors for code give yourself a badness of a 100.
  4. Tabulars and boxes Too many tabulars, especially if they are enclosing data into grid prisons, fancy boxes with gray backgrounds, tables that you have either to turn your head or the book to read them properly give yourself a badness of 100.
  5. Spacing around page elements inconsistent spacing around equations tables and figures, mixed paragraphs some indented others not, give yourself a badness of a 100.
  6. Too much numbering, too many bullets Human brains mostly ignore numbers before text sections; sometimes the rat-tat-tat... of lists and enumerations in general text should be avoided. Give yourself a badness of 50 if you have no valid reason to number your sections.
  7. Rivers If you have rivers in your text, give yourself a badness of a 1000 and start typesetting your books with (all)TeX.
  8. Flushbottom Give yourself a badness of 20 if you use ragged bottom.
  9. Widows and Orphans Ignore both of them until your final version, if a widow exists after your final version give yourself a badness of 50. If an orphan does give yourself a badness of 50.
  10. Quotation marks Avoid them if you are writing in German or accept a badness of 150! Too many quotes and quotations give yourself a badness of 300. This is not so much a typography rule, but if you cannot express your ideas in your own words ...
  11. Business Reports If you managed to have your logo on every page and headers and footers in boxes, give yourself a badness of 500.

As you will observe if you are writing for yourself, i.e., you are not typesetting a thesis or the like you can control badness down to very low limit by judicious manipulation and a little rewriting during the final stages of a manuscript, so I would say a badness of around a hundred should be acceptable. If you writing a thesis anything goes so relax and let LaTeX do its job.

I am curious about your comment on rivers: I think that neither pdflatex nor the more recent engines have support for avoiding rivers. –  Bruno Le Floch May 4 '11 at 22:56
    
@Bruno none do, but the TeX engine tends to produce less obvious ones, as compared to word, unless you have something like tex.stackexchange.com/questions/4507/…, anyway I added 7, as a shameless promotion for TeX:) –  Yiannis Lazarides May 5 '11 at 3:39
    
Awesome answer, thanks! Does a river mean something that happens when you increase \spaceskip's positive stretchability too much? Also, what is the rationale behind striving for flushbottom? –  morbusg May 5 '11 at 5:58

@morbusg Rivers actually look like rivers of whitespace. If you increase interword spacing you are more likely to encounter them. My experience with TeX is that you rarely encounter them, but with Word is like a built-in feature! The rationale behind flushbottom applies mostly for books printed on both sides of the paper. When you open them both the recto page as well as the verso page should have the same number of lines (pretty much) like the top of pages. –  Yiannis Lazarides May 5 '11 at 15:49
    
Please excuse my ignorance -- What's wrong with the standard class headings? What should I use instead? –  Tim N Dec 14 '11 at 16:20

After 3 years of typography lessons I have learned that while permissible only in the most extreme cases, both orphans and widows mark laziness. They disrupt the eyes natural rhythms as they scan the page and disrupt overall continuity of a paragraph or page of text. If you can't handle orphans or widows in LaTex do what you need there and then then put your type in InDesign to clean it up. Lynda.com has a ton of very easy to follow tutorials for basic typography. Also, always kern your titles.

I suggest reading Peter Wilson's Notes on book design.

I do not know of such a list.

Regarding orphans and widows, though: According to some distinguished contemporary typographers (Friedrich Forssman, for example), orphans should not be considered typographic flaws anymore. Widows are also acceptable in many cases, for example if the line in question fills at least half the maximum line width or if there is a decorative line in the header.
