I'm interested in saving space by scaling all characters in a passage of text to, say 95% of their normal horizontal character widths. In Microsoft Word this is done with the Scale field under the Character Spacing tab in the Font formatting dialogue (see the figure).
Is it possible to accomplish the same thing in LaTeX?

microtypepackage (and maybe virtual fonts would be the way to go). But I'd strongly discourage this (on the grounds that this may strongly hinder legibility and aesthetics); there are other ways to save space, ranging from using thesavetreespackage to rewriting your text. Summing up: this may be a good idea only in case of texts noone will read anyway, so why bother;)? – mbork Mar 23 '12 at 6:35microtype. I agree that horizontal scaling should be used only under special circumstances, but the question has merit. – lockstep May 6 '12 at 8:40microtypewas only a guess, I don't know that package very well. – mbork May 6 '12 at 22:38
