Summary

The font-stretch property selects a normal, condensed, or expanded face from a font.

The two 'e' belong to the same fonts. One is condensed, the other normal and can be selected by 'font-stretch'.

This property does not change the geometry of an arbitrary font by stretching or shrinking it. Like font-feature-settings or font-variant, it is merely a mean to choose the most appropriate face of the font, if this one offers several of them.

Note: If the font provides several faces, the one fitting the best with the value of the font-stretch property is chosen. E.g. On OS X, in addition to the more common Bold, Regular, Italic, and BoldItalic faces, the "Helvetica Neue" font proposes a second set of faces with condensed, that is shrunk, characters: Condensed. Browsers supporting font-stretch will use the condensed faces for the value ultra-condensed to semi-condensed and the normal faces for the other (normal and all expanded values).

Font-stretch results with a font having 2 faces, one condensed and one normal.

If the font has no condensed or expanded faces, like the default "Times New Roman" on Mac OS, font-stretch will not have any visible effect as the only suitable face will be used in all cases.:
Font-stretch results with a font having 1 single face.

Syntax

/* Keyword values */
font-stretch: ultra-condensed;
font-stretch: extra-condensed;
font-stretch: condensed;
font-stretch: semi-condensed;
font-stretch: normal;
font-stretch: semi-expanded;
font-stretch: expanded;
font-stretch: extra-expanded;
font-stretch: ultra-expanded;

/* Global values */

font-stretch: initial;
font-stretch: unset;

Values

normal
Specifies a normal font face.
semi-condensed, condensed, extra-condensed, ultra-condensed
Specifies a font face more condensed than normal, with ultra-condensed as the most condensed.
semi-expanded, expanded, extra-expanded, ultra-expanded
Specifies a font face more expanded than normal, with ultra-expanded as the most expanded.

Interpolation

Font stretch values are interpolated in discrete steps. The interpolation happens as though the ordered values are equally spaced real numbers; the result is rounded to the nearest value, with values exactly halfway between two values rounded towards the later value, that is the most expanded one.

Formal syntax

normal | ultra-condensed | extra-condensed | condensed | semi-condensed | semi-expanded | expanded | extra-expanded | ultra-expanded

Example

HTML

<div class="ultra stretch"> This is text with the font extremely expanded</div>
<div class="stretch"> This is text with the font stretched</div>
<div class="normal"> This is text without font stretching</div>
<div class="condensed"> This is text with the font condensed</div>
<div class="ultra condensed"> This is text with the font extremely condensed</div>

CSS

.ultra.stretch{font-stretch: ultra-expanded;}
.stretch {font-stretch: expanded;} 
.normal {font-stretch: normal;}
.condensed {font-stretch: condensed;}
.ultra.condensed {font-stretch: ultra-condensed;}
