Never Put Two Spaces After A Period
Illustration by Slate. Can I let you in on a secret? Typing two spaces after a period is totally, completely, utterly, and inarguably wrong. And yet people who use two spaces are everywhere, their ugly error crossing every social boundary of class, education, and taste.* You'd expect, for instance, that anyone savvy enough to read Slate would know the proper rules of typing, but you'd be wrong; every third email I get from readers includes the two-space error. A Slate Plus Special Feature: Never, ever use two spaces after a period: Listen to Mike Vuolo read Farhad Majoo’s classic takedown of an enduring typographic sin. What galls me about two-spacers isn't just their numbers. Typographers, that's who. Every modern typographer agrees on the one-space rule. Type professionals can get amusingly—if justifiably—overworked about spaces. This readability argument is debatable. But I actually think aesthetics are the best argument in favor of one space over two. Is this arbitrary?
