Em Dash vs. En Dash: A Quick and Simple Guide

Picture of the en dash and the em dash

In the battle of the em dash vs. the en dash it is critical that writers are aware of the major differences between the two punctuation marks and that they ensure they use them correctly and in the appropriate format in their written documents.

The first basic concept to get your head around concerns the length of the punctuation mark. The em dash is the length of a lower case letter “m” and the en dash is the length of the letter “n.” When using the em dash and the en dash you should not leave any spaces between the punctuation and the next word.

Not exactly rocket science is it? However, it’s really their basic usage that you really need to get to grips with when revising your writing.

 

Uses of the En Dash

One of the biggest uses of an en dash is between periods of time where otherwise you may use the word “to”:

The job is suitable for people who already have some experience in marketing and the ideal candidate will be aged 30–40.

The en dash is also often used in the place of a hyphen to combine open compounds:

I’m not really sure how old she is. I think she’s of college–university age.

 

Uses of the Em Dash

Em dashes can be used in the place of a number of punctuation marks including commas, parenthesis, semi-colons and colons and—although many people do use them in formal writing—they are mostly suited to informal documents. Their main use is to convey an abrupt change of topic or thought and they should be used sparingly.

It took a large number of people to push the car up the hill—Katy, James, Joe and Brenda, to name a few.
