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

/* 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;  /* Percentage values */ font-stretch: 50%; font-stretch: 100%; font-stretch: 200%;  /* Global values */ font-stretch: inherit; font-stretch: initial; font-stretch: revert; font-stretch: unset; 

font-stretch

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

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;  /* Percentage values */ font-stretch: 50%; font-stretch: 100%; font-stretch: 200%;  /* Global values */ font-stretch: inherit; font-stretch: initial; font-stretch: revert; font-stretch: unset; 

This property may be specified as a single keyword value or a single <percentage> value.

Values

normal

Specifies a normal font face.

semi-condensed, condensed, extra-condensed, ultra-condensed

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

semi-expanded, expanded, extra-expanded, ultra-expanded

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

<percentage>

A <percentage> value between 50% and 200% (inclusive). Negative values are not allowed for this property.

Note: In earlier versions of the font-stretch specification, the property accepts only the nine keyword values.

The CSS Fonts Module Level 4 spec extends the syntax to accept a <percentage> value as well. This enables variable fonts to offer something more like a continuum of character widths. For TrueType or OpenType variable fonts, the "wdth" variation is used to implement varying widths.

However, note that the <percentage> syntax is not yet supported by all browsers: check the Browser compatibility table for details.

Keyword to numeric mapping

The table below shows the mapping between keyword values and numeric percentages:

Keyword	Percentage
ultra-condensed	50%
extra-condensed	62.5%
condensed	75%
semi-condensed	87.5%
normal	100%
semi-expanded	112.5%
expanded	125%
extra-expanded	150%
ultra-expanded	200%

Description

Some font families offer additional faces in which the characters are narrower than the normal face (condensed faces) or wider than the normal face (expanded faces).

You can use font-stretch to select a condensed or expanded face from such fonts. If the font you are using does not offer condensed or expanded faces, this property has no effect.

Font face selection

The face selected for a given value of font-stretch depends on the faces supported by the font in question. If the font does not provide a face that exactly matches the given value, then values less than 100% map to a narrower face, and values greater than or equal to 100% map to a wider face.

The table below demonstrates the effect of supplying various different percentage values of font-stretch on two different fonts:

	50%	62.5%	75%	87.5%	100%	112.5%	125%	150%	200%
Helvetica Neue
League Mono Variable

Helvetica Neue, which is installed by default on macOS, has a single condensed face in addition to the normal face. All values of font-stretch less than 100% select the condensed face, while all other values select the normal face. League Mono Variable is a variable font that offers something like a continuous range of widths for different percentage values of font-stretch.

Formal definition

Initial value	normal
Applies to	all elements. It also applies to ::first-letter and ::first-line.
Inherited	yes
Computed value	as specified
Animation type	a font stretch

Formal syntax

<font-stretch-absolute>
where <font-stretch-absolute> = normal | ultra-condensed | extra-condensed | condensed | semi-condensed | semi-expanded | expanded | extra-expanded | ultra-expanded | <percentage>

Examples

Specifications

CSS Fonts Module Level 4 # font-stretch-prop

Note: The font-stretch property was initially defined in CSS 2, but dropped in CSS 2.1 due to the lack of browser implementation. It was brought back in CSS 3.
