Ooohhhh, no you don't.
A hyphen is a hyphen. Find it between the 0 and the = on your keyboard. It's used to hyphenate. Hyphenated words, like jack-ass. Or to create compound adjectives, like that hyphen-obsessed Campbell guy.
Don't use a hyphen when you mean a dash. Your text will look empty at best, and vague at worst - like this. A double-hyphen--that's just double-wrong.
Instead, put both your hands to work and type a real dash. Choose from two:
- The M-dash looks like this —. It's so named because it's usually about the width of a capital M. Or imagine a square that's as wide as your font is tall. ☐
- The N-dash – guess why it's called that – is a little narrower, about half the width of an M.
Choose your weaponWhen you want a dash, here's a rare gift from the snobby typographical world: either choice is acceptable. [Gasp!] But before you go dancing naked in the streets, let me add one sniff of snobbery: the N-dash always has a space before and after it – like this. The M-dash never has spaces—use it like this. An M-dash with spaces around it creates way too much division — see what I mean?
Beyond that, you can choose which you like better.
No wait—not quite. Be consistent. Pick a team. Be an Emmie or an Ennie.
In the US, the M-dash is far more common. Europe is more likely to use the N-dash.
How to make a mad dashOn a Mac: create an M-dash using shift +option + - . For the N-dash, select option + - .
On a PC: the M-dash is found at control + alt + - . If that doesn't work, try alt + 0151. For the N-dash use alt + - . If that doesn't work, try alt + 0150. If you want to make it easy on yourself, you can type the lazy way with a space-dash-space, then do a search-and-replace through your final draft to get the proper dash you want. Software often includes these in a "Special Characters" choice under the <Edit> menu.
Just like that, you're legit!
Another use for the N-dash: it's the proper choice for a range of numbers, like from 100–200.
More digression: M and N are typographical measurements that are relative to the font being used. That is, each gets bigger or smaller as the type does. So there's also an M-space, which is really fat, and an N-space, which is half as wide, but noticeably bigger than a standard space.
For the type geek, there's also a minus sign in your arsenal. It sits a little higher than a dash, so it aligns better with digits. Here are dashes: 1–2–3–4–5 vs minus signs: 1−2−3−4−5.
Now you can dash off, knowing you're doing it right. And it's suddenly going to bug you when other people don't.
Welcome to being a type snob.
