En-dash
The en-dash (–), also known as the en rule, is one en in width: half the width of an em-dash, but longer than a hyphen. The en-dash is commonly used to indicate a range of numbers, or to represent a mathematical minus sign.

Monospaced fonts such as Courier or DP Sans Mono that mimic the look of a typewriter have the same width for all characters. Thus, they have only a single hyphen glyph, so a hyphen (-) and an en-dash (-) are represented by exactly the same character. The use of the term en-dash at DP tends to refer to the use made of it. So the above examples would all be called en-dashes. The below examples would be called hyphens.
- New York–London flight
- Mother–daughter relationship
- The McCain–Feingold bill
The en-dash, like the em-dash, is not included in our character suites, and therefore cannot be used during proofreading. In the rounds, a single hyphen is substituted for an en-dash character.
More information on hyphens, en-dashes, and em-dashes is available in the Dashes, Hyphens, and Minus Signs section of the Guidelines.
