This may seem inflammatory to some, and for some strange reason, this issue brings out the worst in people. Forget Liberal or Conservative, are you a Single-Spacer or a Double-Spacer?
Now, I happen to be an adamant Single-Spacer, and I’m always amazed at how many people continue to use the double-space (or em-space) after every period. It seems like an awfully inefficient use of time and energy in our “Time is Money” world, not to mention a waste of space! But I don’t dare mention it to my authors and contributors, because I might be setting myself up for a full-blown attack: “That’s what I was taught, so it must be right” or “It just looks better with two spaces.” And we all know that you can’t argue with belief.
So I just search-and-replace them quietly.
The Chicago Manual of Style, widely regarded as the standard for publishing and communications, gives this example in their Q&A section:2
Q. About two spaces after a period. As a US Marine, I know that what’s right is right and you are wrong. I declare it once and for all aesthetically more appealing to have two spaces after a period. If you refuse to alter your bullheadedness, I will petition the commandant to allow me to take one Marine detail to conquer your organization and impose my rule. Thou shalt place two spaces after a period. Period. Semper Fidelis.
A. As a US Marine, you’re probably an expert at something, but I’m afraid it’s not this. Status quo.
How can you argue with CMS? But if you need more convincing, let’s look at a couple of textbooks on typesetting and typography, the guidebooks for today’s professional designers. In The Elements of Typographic Style, Robert Bringhurst outlines the history of the double-space:
“In the nineteenth century, which was a dark and inflationary age in typography and type design, many compositors were encouraged to stuff extra space between sentences. Generations of twentieth-century typists were then taught to do the same, by hitting the spacebar twice after every period. Your typing as well as your typesetting will benefit from unlearning this quaint Victorian habit.”3
But even Mr. Bringhurst seems to be adding more emotion than argument, with his “dark and inflationary age”, “encouraged to stuff extra space” and “quaint Victorian habit.” Perhaps rather than shaming you out of your bad habits, I should try to convince you with reason. James Felici does a better job of this in The Complete Manual of Typography:
“The use of wide spaces after sentences (ems or even wider) goes back to at least the mid-eighteenth century, a hundred years before the typewriter was invented….As a style, this died out in the twentieth century, with its last vestiges appearing in the 1940s, decades before the rise of computerized typography. It remained a custom on the typewriter, though, because double spaces are proportionally more appropriate for the airy monospaced faces standard on those machines….Proportionally spaced fonts, though, contain word spaces specifically designed to play the sentence-separating role perfectly. Because of this, the double word space at the end of a sentence creates an obvious hole in the line….While this may once have been a prevalent style in publishing, it’s out of fashion today, so when it does appear, it looks like a mistake.”4
And this is my argument exactly. It looks like a mistake! What if you, the author, have failed to place two spaces after every period? Then some of your sentences have two spaces and some have one, and the whole piece of writing looks inconsistent. Or worse, the extra spaces add strange line breaks or rivers throughout a page. Talk about a typesetter’s recurring nightmare. The only way to ensure consistency is to take ALL double spaces out. And as a copyeditor, consistency will always be my number one concern.
If my arguments and reputable sources have not convinced you, perhaps you are at least coming to understand why this style is changing. Dave Bricker from the theworldsgreatestbook.com, whose article I enjoyed very much, was once on the Double-Spacer side of the argument but has recently changed sides. He has a soft spot for you die-hards, and had the following to say:
“Your typesetter will remove double-spaces from your manuscript; that’s a simple fact. Though writers are encouraged to unlearn the double-space typing habit, they may be heartened to learn that intellectual arguments against the old style are mostly contrived. At worst, the wide space after a period is a victim of fashion.”5
I encourage you to check out Mr. Bricker’s very interesting article, which has many examples of this and other typographical styles as they change through historical documents of the past three centuries. Fascinating!
