En dash vs. em dash is one of the trickiest punctuation issues there is. 

They look very similar and are sometimes used for the same purpose (depending on what style guide you use). 

Below I explain what each dash is used for, provide examples, and show you how to create these marks in different word processors. 

(Please note that I used The Chicago Manual of Style (CMOS) as my reference guide unless otherwise noted.)

What is an en dash used for?

The main purpose of an en dash (–) is to connect inclusive dates and numbers. It essentially means “to” or “through.”

Although it means through or to, if the word from precedes the number range, the word through or to should be used instead of an en dash. And if the word between precedes the number range, the word and should be used instead of the en dash.  

Examples:

She works from 9 to 5; what a way to make a living.  

Between 1:00 p.m. and 2:00 p.m. each day is blocked out for Murder She Wrote.

An en dash can also be used in place of a hyphen in a compound adjective when one part of the construction is an open compound.

En dash examples

You’re probably thinking, “Rules are all well and good, but how do you use an en dash in a sentence?”

Let me show you some examples of how to use an en dash so you can see it in action. 

Read chapters 513 of The Chicago Manual of Style if you want to become a grammar guru. 

September 4–11 is reserved for the annual Word Nerds Unite festival. (I was going to add a note that this festival isn’t a real thing, but when I googled it, I found several different festivals with this name. How cool is that!)

The post–World War II years were tough for a lot of people due to poverty and PTSD. 

When should I use an em dash?

Now that we know what an en dash is used for, let’s move on to the em dash. 

The em dash (—) is much more versatile than the en dash. 

Em dashes can be used at the end of a sentence or in pairs to draw attention to parenthetical information or additional “that is” thoughts within a sentence.

Em dashes can replace a comma where a comma doesn’t provide a strong enough break.

They can also be used in place of parentheses. Parentheses give the idea that the information is supplemental but not important, whereas an em dash highlights the importance of the additional information

Warning: Beware of using hyphens in place of em dashes. Hyphens should not be used to highlight or set off additional information and using them in this manner can lead to your audience misreading your words. 

An em dash may be used to signify a sudden break or interruption in dialogue.

Em dashes are also sometimes used as bullet points in a vertical list in informal writing. 

There are some other less well-known uses for the em dash; for example, the 2-em dash and the 3-em dash. 

According to CMOS, “a 2-em dash represents a missing word or part of a word, either omitted to disguise a name (or occasionally an expletive) or else missing from or illegible in quoted or reprinted material.”

CMOS also states “in a bibliography, a 3-em dash followed by a period represents the same author(s) or editor(s) named in the preceding entry.”

Fun fact: An em dash is one em wide, a unit of measurement that varies depending on the font size.

Em dash examples

Miss America is hoping for world peace—or so she says!

As long as I have three things in my pantry—bread, chocolate, and ice cream—all is right in the world.

Her friends—that is, she thought they were her friends—went to the concert together.

British usage vs. American usage

Usage of dashes can vary between British English and American English. 

Fun fact: The en dash is called the en rule in British English, and the em dash is called the em rule. 

According to CMOS, “in British usage, an en dash (with space before and after) is usually preferred to the em dash as punctuation in running text.”

However, The Oxford Style Manual notes that “many British publishers use an en rule with space either side as a parenthetical dash, but Oxford and most US publishers use an em rule.”

So both CMOS and The Oxford Style Manual advocate using a closed-up em dash to set off parenthetical information, but some British publishers may use spaced en dashes instead.

Consistency is key when deciding which style you’re going to follow! 

Spacing of en dashes and em dashes

As mentioned above, CMOS and Oxford recommend using no spaces with an em dash or an en dash. 

AP Style recommends putting a space before and after the em dash.
