Indenting paragraphs versus space between paragraphs A lot of people doing their own typesetting fall into the trap of putting space between paragraphs rather than indenting paragraphs. This seems to have come about through the influence of typewriting, where it is easier (i.e., quicker) to type the <return> key twice rather than a <return> and a <tab> key. TeX and LaTeX, by default, indent paragraphs rather than insert space between paragraphs, but many users go to a lot of trouble to reverse this. (It is actually very easy to do, and involves setting 2 commands: \parindent and \parskip.) Jan Tschichold, one of the most influential typographic designers of this century, has this to say on the subject: Indentation is technically and aesthetically the best and simplest way to distinguish paragraphs and it would be foolish to regard it as out of date. ... It is better to distinguish paragraphs certainly by means of indentation than uncertainly by line endings. ... Extra space between paragraphs should never be used instead of indentation in books and magazine work; it is excusable only in newspapers and cheap pamphlets. \cite[page~48]{Tschichold} The advantage of indention is that it is immediately obvious that a new paragraph has started. Vertical spacing, on the other hand, needs the previous paragraph before it can be decided that a new paragraph has started. Furthermore, if a paragraph starts at the top of a page, it is impossible for the reader to know whether it is a new paragraph or the continuation of the previous paragraph. The same problem occurs when starting a new paragraph after a list or other displayed text: it is very difficult to know whether it is a new paragraph or a continuation of the same paragraph. Vertical space is better employed to emphasize headings, quotes, lists, etc. Here, it clearly displays the text. Indentation after a heading? The Chicago Manual of Style (page 575) suggests not indenting the first paragraph after a heading. Why? The absence of indentation draws attention to both the paragraph and the heading. Summary Modern typography is all about `form following function', i.e., each part of the design has to justify its existence in terms of enhancing readability. Indenting paragraphs is an economical way of signalling the start of a new paragraph (and hence new idea). It then leaves vertical space to be employed to display text such as extracts, lists, etc. Under NO circumstances should paragraphs be both spaced and indented.

You may have a point with the typewriter. However, I think that the reason (if you are correct) is that typewritten text is mostly ragged-right, and then indentation looks ugly. > TeX and LaTeX, by default, indent paragraphs rather (plain TeX and LaTeX, but I'll let that go.) >than insert space between paragraphs, but many users >go to a lot of trouble to reverse this.

Try setting \parskip, and then forcing only half of that amount around an environment.

Vertical spacing, >on the other hand, needs the previous paragraph before it >can be decided that a new paragraph has started. Non-argument. You can only see that something is indented by comparing it to the previous line (and you didn't want this for vspacing), or to the next, which is even worse because now your looking up and down the page. >Furthermore, if a paragraph starts at the top of a page, it >is impossible for the reader to know whether it is a new >paragraph or the continuation of the previous paragraph. So how about indenting pars that are top of page, and using parskip for the rest? I can do that in TeX. >The same problem occurs when starting a new paragraph after >a list or other displayed text: it is very difficult to >know whether it is a new paragraph or a continuation of the >same paragraph. I always found this a bogus problem. Indenting after a list is ugly. Unless the part after the list continues mid-sentence, this is a natural place to take a breadth and start a new division of the text. No indentation necessary. > Vertical space is better employed to emphasize headings, >quotes, lists, etc. Here, it clearly displays the text. ^^^^^ But above you mentioned the possibility that a list can be part of a paragraph. You still want vspace in that case? Or maybe sometimes you want it, sometimes you don't. The result is called 'a mess'. >\bibitem{Tschichold} >Tschichold, J. >\newblock {\em Assymetric Typography}.

Let's hear it. Indeed. BTW, most of the books (novels) I've seen that were printed in a certain country [famous for its books!] appear to favor a do-nothing paragraph separating style, i.e., neither indentation nor vertical space. Thus, the only aid to recognizing a new paragraph is that the trailing line of the previous paragraph doesn't quite make it to the right margin. (Ergo, this style will not work for raggedright text, hence I can't demonstrate it in this article.) Strangely enough, the result is very pleasing, and not misleading, as graeme@otago's reasoning might suggest, since care is taken to ensure that a sentence that finishes a paragraph doesn't ever end on the right margin. (In LaTeX, this can be accomplished by ending all paragraphs with a ~\mbox{ }.) (A further guideline seems to be never start a sentence on a page unless it starts a paragraph.) Incidentally, this style really saves space -- including the tiny par-indentaton space! --d

There are many technical publications in which various equations and examples appear on lines by themselves in the middle of paragraphs. These examples require space around them, and therefore imply that the style of the surrounding document include space between paragraphs. Unfortunately in such cases the space alone is insufficient for indicating the start of paragraphs, since it often happens that a paragraph continues after an example. Regrettably, such texts are clearer when paragraphs are indented and spaced. A. V. Le Blanc ZLSIIAL@uk.ac.mcc.cms

The "rules" for typewritten text are *different* because they use fixed-width fonts and a limited character set -- just like plain-ASCII articles. The blank line between paragraphs arguably helps open up the page. As you can see, I use blank lines as separators (if only to be consistent with all the computer program that rely on this heuristic). > TeX and LaTeX, by default, indent paragraphs rather > than insert space between paragraphs, but many users > go to a lot of trouble to reverse this. Actually \parskip for TeX is 0pt plus 1pt -- which stretches horribly on bad pages. (It ought either to be 0pt exactly or some positive amount.) If you want to argue style on the basis of legibility, you might like to cite some research one way or the other. My understanding is that there is almost no evidence one way or the other -- at least not enough to over-rule the aesthetic sense of the typographer. (The same applies to ragged-right vs. justified.) Beginners should think twice about altering style parameters though. > Modern typography is all about `form following function', > i.e., each part of the design has to justify its existence > in terms of enhancing readability. I beg to differ. There is still a role for people with an eye for beautiful typesetting as well as functional typesetting. Presumably the `form over function' people are still puzzled as to why there is more than one of each sort of font in existance -- if you already have Times, why bother making Bookman? > Indenting paragraphs is an economical way of signalling the > start of a new paragraph (and hence new idea). It then > leaves vertical space to be employed to display text such > as extracts, lists, etc. > Under NO circumstances should paragraphs be both spaced > and indented. I use no paragraph skip when setting "plain text". A friend of mine setting his thesis -- with many displayed formulae -- used a 1/2ex paragraph skip. He argued that the space on either side of all the displays and lists meant that the the division into paragraphs was obscured. Even though this is Against the Lore, I think it worked OK. I think that indentation should not be dropped if there are displays etc. because then it does become difficult to spot new paragraphs. This implies that sometimes it might seem appropriate to have both \parindent and \parskip nonzero. > \bibitem{Tschichold} > Tschichold, J. > \newblock {\em Assymetric Typography}. > \newblock Faber \& Faber Ltd in co-operation with Cooper \& Beatty, Ltd > (Toronto), London, 1967. > \newblock Translated by Ruari McLean.

The choice of font is as much one of function as of form.

Printing started in Germany, but the Italians were the first to have high quality, the Dutch and the Spanish have had their period, the French were influential in the 19th century, and England has had some good bookprinters too... >do-nothing paragraph separating style, i.e., neither indentation nor >vertical space.

>>>>> On 14 Mar 91 05:21:19 GMT, graeme@otago.ac.nz said: > Indenting paragraphs versus space between paragraphs > [And a lot of reasons why it's a good thing] Well yes. But it's more complex than that isn't it? In the case where some document consists just of lots of paragraphs of reasonable length (i.e. typical work of fiction) then this is a good way to do things, and certainly I think leaving whitespace between paras looks horrible for such documents. But there are documents where this style looks horrid. For instance, consider a document where there are many very short paragraphs -- less than one line. What you end up with in this case is whole regions of the page with indentation, or whole regions of the page which have every other line or so indented. This looks really nasty I think, and some other method of marking paragraphs is preferable there. Actually when I (hand) write letters I just run on paragraphs, marking them with a pilcrow. This has precedents in books I've seen. But TeX can't do this because of memory constraints. (Please don't post some obscure hack that gets around this, I'm sure it can be got around, but it shouldn't need to be obscure to do it!) --tim
