Spacing after the period at the end of a sentence is a typesetting problem, not a writing problem. That is, writers can do whatever they want; it’s not their job to make it right. It’s up to the typesetter (web browser, WYSIWYG program, printer, etc) to make it look right. ---

I have written myself various macros, but I haven’t stumbled across anything that will reduce 2-3 blank lines to one (it’s easy to add them with a macro, but remove them?), which would be pretty damn useful with some of the stories I get. The order of things is important! First, globally replace “^w^p” with “^p”. This will remove all whitespace (spaces & tabs) from the beginning of every paragraph. Then replace “^p^p” with “^p”. This removes single blank lines between paragraphs, but still leaves a blank line where there were two of them. Repeat the second step to remove those. ---

Two. Always and automatically. Could I enforce it on html I would. One space is vulgar, and it’s nice to drive people insane if they care so deeply. ---

No. Newspapers and magazines may strive for that (they typically use AP style), but books by and large do not (they typically use Chicago style, which doesn’t necessarily serve to conserve space). Chicago style, as cited above, uses one space. ---

I learned to use two in grade school, and like all the other outdated bits of idiocy from that time, I left it behind. One space for me, thanks. ---

I don’t care if word processing programs such as MS Word have made two spaces supposedly “obsolete”. Type or MS Word, a document still LOOKS better with two spaces. White space is a good thing. I don’t get the hatred for the two-space, other than the whole “you old geezers, that was then, this is now” mentality. One space is not more “modern” or whatever, and it certainly looks less aesthetically pleasing than two. ---

I’m a self-taught typist who started on an used Selectric. I used one space on it and continue to do so on computers now. ---

Damn, these one space two space threads are on what seems like every other message board lately. I use two, because in my eyes it better distinguishes individual paragraphs. I also use old-school plain text email, where it makes more sense. If you use one or two, though, I don’t care. A nerdy compromise would be to use the Unicode space-and-a-half character. Like what I did in this post. ---

> [@CanvasShoes](#): > > One space is not more “modern” or whatever, and it certainly looks less aesthetically pleasing than two. It looks like rivers of space to me. The terminal punctuation mark already breaks the space between sentences, and a single space is all that is necessary. Any more, and it causes me to visually “hiccup” between sentences. [Wikipedia on sentence spacing](http://en.wikipedia.org/wiki/Sentence_spacing): > [@](#): > > The Complete Manual on Typography (2003) states that “The typewriter tradition of separating sentences with two word spaces after a period has no place in typesetting” and the single space is “standard typographic practice”.[41] The Elements of Typographic Style (2004) advocates a single space between sentences, noting that “your typing as well as your typesetting will benefit from unlearning this quaint [double spacing] Victorian habit.”[9] > > David Jury’s book, About Face: Reviving the Rules of Typography (2004)—published in Switzerland—clarifies the contemporary typographic position on sentence spacing: > Word spaces, preceding or following punctuation, should be optically adjusted to appear to be of the same value as a standard word space. If a standard word space is inserted after a full point or a comma, then, optically, this produces a space of up to 50% wider than that of other word spaces within a line of type. This is because these punctuation marks carry space above them, which, when added to the adjacent standard word spaces, combines to create a visually larger space. Some argue that the “additional” space after a comma and full point serves as a “pause signal” for the reader. But this is unnecessary (and visually disruptive) since the pause signal is provided by the punctuation mark itself.[42] As for the legibility issue, there do not seem to be any conclusive studies. Wikipedia references this: > [@](#): > > Direct studies include those by Loh, Branch, Shewanown, and Ali (2002), Clinton, Branch, Holschuh, and Shewanown (2003) and Ni, Branch and Chen (2004) with inconclusive results favoring single or double spacing.[102] The 2002 study tested participants’ reading speed for single and double sentence spaced passages of on-screen text. The authors stated that “the ‘double space group’ consistently took longer time to finish than the ‘single space’ group”, but concluded that “there was not enough evidence to suggest that a significant difference exists”. However, there is also this: > [@](#): > > A widespread observation is that increased sentence spacing creates “rivers”[109] or “holes”[110] within text, making it visually unattractive, distracting, and difficult to locate the end of sentences.[111] Comprehensive works on typography describe the negative effect on readability caused by inconsistent spacing,[112] supported in a 1981 study which found that “comprehension was significantly less accurate with the river condition.”[113] Another 1981 study on cathode ray tube (CRT) displays concluded that “more densely packed text is read more efficiently … than is more loosely packed text.”[114] This conclusion is supported in other works as well.[112] ---

I guess it is a matter of personal choice whether your computer-generated text should look like a professional publication or a 70’s era typing class. It is up to the author and what message is sent by the look of the document. When I took typing several decades ago, 2 spaces were the rule.

Any more, and it causes me to visually “hiccup” between sentences. If you don’t pause between sentences, they shouldn’t really be separate sentences. I just now realized why I use so many paragraphs on message boards. It’s because it’s harder to separate sentences that don’t have two spaces between them, so ideas need to be that much more related to each other in order to justify grouping them together so closely. For instance, if I were typing this out in a medium which allowed for double spacing, this post would probably have been two, possibly only one, paragraphs long. Who’s saving space _now_?
