What are the differences between the Em Dash, En Dash and Hyphen, and when should we use them.
The first thing you’ll notice about the Em and En Dash and the Hyphen is they are different sizes with the Hyphen being the shortest followed by En, then Em. Beyond this simple aesthetic, what are the differences and when do we use them?
The Hyphen is the shortest of the dashes and the easiest to find as it is present on the main keyboards. It is used when two words are related and work together to function like one adjective — known as a compound adjective — and generally comes before a noun.
There is no need to hyphenate when the noun comes before the compound adjective ie The drug is fast acting.
Hyphens are also used with the prefixes Ex, Self and All.
And written fractions are always hyphenated.
Words ending in ‘ly’, or the word ‘very’, are rarely hyphenated.
Hyphens are also used in all written compound numbers twenty-one through ninety-nine.
En Dash –
The middle sized dash— En— is the length of an ‘N’ and is probably the easier one to navigate in your writing given it’s very specific use in showing ranges—typically dates, times and numbers.
