In modern fonts, the length of the en dash is not standardized, and the en dash is often more than half the width of the em dash. The en dash, en rule, or nut dash – is traditionally half the width of an em dash. The Linux Libertine font also has the figure dash glyph. In TeX, the standard fonts have no figure dash however, the digits normally all have the same width as the en dash, so an en dash can be a substitution for the figure dash. In informal usage, the hyphen-minus - ( U+002D - HYPHEN-MINUS), provided as standard on most keyboards, is often used instead of the figure dash. The minus sign − ( U+2212 − MINUS SIGN) glyph is generally set a little higher, so as to be level with the horizontal bar of the plus sign. In contrast, the en dash – ( U+2013 – EN DASH) is generally used for a range of values.

(Most fonts have digits of equal width.) It is used within numbers such as the phone number 555‒0199, especially in columns so as to maintain alignment. The figure dash ‒ ( U+2012 ‒ FIGURE DASH) has the same width as a numerical digit.

An (unspaced) em dash or a spaced en dash can be used to mark a break in a sentence, and a pair can be used to set off a parenthetical statement.Usage varies both within English and within other languages, but the usual conventions for the most common dashes in printed English text are these: To scratch your Head, and bite your Nails.
