While typewriter typists in the United States were traditionally taught to use two spaces between sentences, this is becoming less common and many sources now recommend having only one space, although this topic is still controversial.
This obviates the problem, as a period will always appear at the end of a line and the spacing after it becomes moot.
This is particularly useful when plain text files based on a markup language (such as HTML, TeX, or Wiki markup) are edited by multiple people using a version control system where it helps to facilitate comparison of changes and avoid merge conflicts.
In most markup languages, a single line feed in the source is rendered as a simple space, while two linefeeds generate a paragraph break.
This approach allows the source to be easily manipulated and versioned, while the rendered output still keeps the regular flow and justification abilities of running text.
The title text uses single spaces between the back-and-forth quotations; but within each quotation, the quoted speaker's preferred spacing is used.
In particular, when the single-spacing advocate claims to be using double spacing, this is indeed a lie.
Randall's mocking characterization in the title text of overzealous advocates using the phrase "WAKE UP, SHEEPLE" has appeared in previous comics 496: Secretary: Part 3 and 1013: Wake Up Sheeple.
I'm wondering if the title text refers to the habbit many people have of slamming on their space key creating a very load sound- hence you can hear the difference between one space and two. But I'm not confident enough to edit the page 18.104.22.168 19:12, 1 December 2020 (UTC)
One line per sentence is reminiscent of a diagrammed/formal logic argument in philosophy. It would be a much more effective convention to help people parse and interpret content and validity of e.g. political claims. 22.214.171.124 17:21, 2 November 2013 (UTC)

Writing plaintext, I always do two spaces after a sentence ending period.
This is probably because I did in fact start typing on a real typewriter.
In an environment where automatic formatting will take place, like a web page or wiki text, I use the newline.
I have had people in this wiki collapse my multiple line forms to one of the others.
(I was disappointed.)

The 'third way' is a little underappreciated here: it divides the text into self contained logical units, and makes text processing tools (grep, diff etc.) much more usable.
Proper text rendering engines (TeX, HTML, etc.) already make this assumption and group sentences accordingly.
If only I realized this earlier, it would have made my thesis revisions much more easier.
In fact, up to this moment, I thought I was that lone guy in the comic.

- As a programmer, I find nothing weird in adapting your style to language. Writing two spaces in HTML or TeX is useless, as they won't render as two spaces anyway. (While using for this purpose nonbreakable spaces, which would render, is a crime.) -- Hkmaly (talk) 10:48, 1 November 2013 (UTC)
- It would also render incorrectly if the period was close to the end of a line. If the markup is [last word of sentence][period][nbsp][space][next sentence], the last word of the first sentence could end up on the next line unnecessarily. But if it's [last word of sentence][period][space][nbsp][next sentence], the next line of text would start with a space, which is much worse.--Rael (talk) 15:16, 1 November 2013 (UTC)
- I end my sentences with a line break, a % and another linebreak. Only after commata etc i use a single line break. Oh, and don't forget to protect the space after points used in abbreviations, not as full stops, by a backslash. Most TeX increase the length of the space after a full stop a bit. Bit question: Why don't double space people, when using Word not just use a longer space instead of a double space. Noone would have the idea to indent a paragraph or substitute a tab with a series of spaces.184.108.40.206 03:11, 2 November 2013 (UTC)

So, why did double spacing after a period ever exist? It doesn't seem necessary. PheagleAdler (talk) 07:31, 1 November 2013 (UTC)
- Here's the standard explanation: on typewriters, each character takes up the same amount of space. So a lower-case "i" takes up the same amount of space as a capital "M". This is called a monospace font. When typing, if you just put a single space after the end of period ending a sentence, the reader doesn't necessarily get the sense that a new sentence has started. This is particularly true if you were typing in all caps, as might be common on some types of forms or documents. Two spaces, however, does the job nicely. In theory, with modern proportional-width fonts, this is unnecessary. Rylon (talk) 23:36, 1 November 2013 (UTC)
- Here's the researched explanation: http://www.heracliteanriver.com/?p=324 So technically, an em-space after a period, an en-space after a comma. Or you know, whatever you want. 126.96.36.199 06:22, 17 July 2015 (UTC)
even though i learned typing on a typewriter, to this day i had never heard of the double space thing. maybe it's a US only thing, like the stupid french with spaces BEFORE punctuation marks. Peter (talk) 07:54, 1 November 2013 (UTC)
- I've always taken the double-space thing as a US thing. Some editors like emacs default to it, which is really annoying. That said, as a frenchman, the "space before punctuation" is normal to me and it is part of the codified typography -- and I think this is actually an important distinction to make. Is this double-space vs single-space something codified somehow? As a last word, I need to be nitpicky: the exact French typography rule is "a space before punctuation made of two parts (namely colon, semi-colon, exclamation/question mark) and no space before punctuation made of a single part (dots, commas.)" It's a very deterministic rule that is easy to apply (whether one agrees to it or not.) Ralfoide (talk) 16:40, 1 November 2013 (UTC)
- This is a common question from the French and some other nationals. The answer is that English does not work that way. There is no official codified version. The most you have is small pockets of codification within an organization, such as The University of Boulder, or UPI or the US Army. If you're working in or with such an organization you should use their standard. If you try to extend any such standard to the rest of the world you are a nasty egomanical control freak who should be chopped into pieces and fed to the fishes.--188.8.131.52 18:25, 4 November 2013 (UTC)
As a german typographer I have to say I’m shocked! Two spaces per period? A space before punctuation?!

As a(n automatic) two-spacer person (just you watch, I'll use 'em here, despite it obviously not being rendered), it's just what I learnt, back in the '70s, here in the UK. I've no idea why I learnt it. However, it may stem from the same root as the 'rule' in handwriting (not biros, but nibbed pens dipped in ink... wow, I feel old, but it was at primary school) that we use a gap as big as our our (very little) little-fingers to separate sentences. I imagine differentiating full-stops (US: periods) from commas in the messy medium of ink might be a valuable visual indicator as to what a given smudge might actually be. So, anyway, double-spacing. On the other hand I should report that, "I've dropped the habit it of appropriate punctuation prior to quotes," I say, "despite being the way I learnt it." And instead I will drop "<- Commas from that sort of position," you see, "even through I'll keep the ones that are semantic pauses." You see how my standards are slipping? Anyway, good comic.

- I'm in the same boat this this bloke. I don't get the typewriter tie in. I seem to recall being taught to use a finger gage correct gap of whitespace to leave between the end of one sentence and the beginning of the next. This was in an American small town southern school in the early 1980s. I assume it was for readability. 18.104.22.168 16:16, 1 November 2013 (UTC)

There's a FOURTH way! I receive a "Weekly Update from Senator Tim Scott" HTML formatted email about once a week (unsurprisingly) which, in lieu of spaces between words, uses a carriage return and a linefeed. This alleviates the question of how many spaces between sentences completely! It also renders as oneverylongword in my email client. Ie:

I think the finger space was to help kids create clear separation while developing their proficiency at penmanship.
I think the 2x space is a fall out from the fixed width formatting of typewriters to help assist the reader (or proof reader) with the start and end of a sentence.
Double spacing has almost become OCD for me. I can't help it. Of course I also leave paragraph marks on while I type as well. I wonder if the French would require a space before a double quote, "The author ponders. "
I think we could improve old school cryptography if we just used carriage returns and ignored the 'new' line.
I might be able to accept and adopt the single space rule if I can make my spaces default to twice the point size of every other character in the style.

I'm not from the US so I never actually heard about a rule with two spaces. From my point of view the rule is stupid, really dumb. Just let go of it! There is no reason for it.

The 2 spaces used in (early) PCs and TypeWriters (and TTYs) could be caused by the too little difference between a «.» and a «,» with little fonts on CRTs (320*200px with 8*8px single letter with <16" monitors with a signal trought an RF cable, for a C64), dot-printers (like 60*75 dpi (h*v), 9*9 per character, for an Epson MX-80) and typewritten sheets (maybe with dirty sort/type)?

I have an easy solution to the debate.
Just press the TAB key after each sentence (doesn't work here, because of editing reasons).
google docs actually enforces the one space style for capitalization.
