En/Em dash length for condensed style font

Should I still follow the by-definition-rule of their length? or some other way to follow in condensed/compressed style font?


  • Make the hyphen work first. Then narrow the other dashes so that they harmonize with letters but aren't mistaken for hyphens.
  • What is the traditional way of determining length of hyphen btw?

    On the side note, Any idea if this information is indeed recommended for determining vertical metrics? https://www.glyphsapp.com/tutorials/vertical-metrics
  • I thought the hyphen was supposed to be approximately the width of a lowercase i (including sidebearings). However, when I look at various typefaces, I see that this varies considerably (some hyphens are longer, and others are shorter).

    Perhaps the width can be adjusted "to taste"?
  • Bringhurst says the hyphen is now standardized to a quarter em, for what that's worth.

    It seems clear to me that with condensed or expanded designs, such an em-based standard isn't going to work. But Bringhurst is usually talking about text types. 
  • I tend to make it about the width of the /W, give or take a little. It has to work with the design so full width doesn't work for me.
  • I’ve read that hyphen is a quarter em, endash is half em, and emdash is equal to an em (which IMHO is often too much, as you can see in Adobe Caslon). I’d say it depends of other proportions, most importantly x-height and width of the letters.
  • George, are you talking about the em dash? That sounds awfully wide for a hyphen.
  • In former times, the drawing sizes of typefaces were much more standardized than today. Looking back at Monotype casters, each font had a "set width" that indicated the width of 18 spacing units (one horizontal em) at a certain font size. For normal proportions, the "set" equaled the font size. For a condensed font, the set could for example be 10, while the font height (apparent size) would be 14 pt. Basically this meant the machine operated like it would for a 10 point font, just the letters would be taller than normal.

    The definitions of the widths of hyphens, en- and em-dash would make much more sense in connection to those horizontal ems than to the vertical font size.

    Hmm. I’ve never made a hyphen as narrow as a quarter em. And I just checked a handful of Font Bureau fonts I’ve worked on production for and couldn’t find one either.
  • Thomas, yes. I see now the topic had veered off into hyphen territory.
  • For any style of font, I have understood that somekind of a rule is that en-dash width is width of /n and em-dash width of /m. I wonder where I got this "rule".
  • ...aaand I just noticed the en dash = width of n?-thread. Good insight.
