font-width

[!NOTE] The font-width property is the modern replacement for {{cssxref("font-stretch")}}, which is a legacy alias. While font-width is the specification's preferred name, font-stretch currently has broader browser support. Check the fallback example and browser compatibility table for details.

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

css

font-width: condensed;

css

font-width: expanded;

css

font-width: ultra-expanded;

css

font-width: 50%;

css

font-width: 100%;

css

font-width: 150%;

html

<section class="default-example" id="default-example">
  <p class="transition-all" id="example-element">
    London. Michaelmas term lately over, and the Lord Chancellor sitting in
    Lincoln's Inn Hall. Implacable November weather. As much mud in the streets
    as if the waters had but newly retired from the face of the earth, and it
    would not be wonderful to meet a Megalosaurus, forty feet long or so,
    waddling like an elephantine lizard up Holborn Hill.
  </p>
</section>

css

@font-face {
  src: url("/shared-assets/fonts/LeagueMono-VF.ttf") format("truetype");
  font-family: "League";
  font-style: normal;
  font-weight: normal;
}

section {
  font-size: 1.2em;
  font-family: "League", sans-serif;
}

Syntax

css

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

/* Percentage values */
font-width: 50%;
font-width: 100%;
font-width: 200%;

/* Global values */
font-width: inherit;
font-width: initial;
font-width: revert;
font-width: revert-layer;
font-width: unset;

This property may be specified as a single keyword or {{cssxref("<percentage>")}} value.

Values

normal
- : Specifies a normally condensed font face.
semi-condensed, condensed, extra-condensed, ultra-condensed
- : Specifies a more condensed font face than normal, with ultra-condensed being the most condensed.
semi-expanded, expanded, extra-expanded, ultra-expanded
- : Specifies a more expanded font face than normal, with ultra-expanded being the most expanded.
<percentage>
- : A {{cssxref("<percentage>")}} value between 50% and 200% (inclusive). Negative values are not allowed for this property.

Keyword to numeric mapping

The table below shows the mapping between the 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-width 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-width 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 condensed face, and values greater than or equal to 100% map to an expanded face.

The table below demonstrates the effect of setting different percentage values of font-width on two different fonts:

css

@font-face {
  font-family: "Inconsolata";
  src: url("https://fonts.gstatic.com/s/inconsolata/v31/QlddNThLqRwH-OJ1UHjlKENVzlm-WkL3GZQmAwPyya15.woff2")
    format("woff2");
}

@font-face {
  font-family: "Anek Malayalam";
  src: url("https://fonts.gstatic.com/s/anekmalayalam/v4/6qLUKZActRTs_mZAJUZWWkhke0nYa-f6__Azq3-gP1W7db9_.woff2")
    format("woff2");
}

The following screenshot shows how the above table is rendered, in case your browser doesn't support the font-width property:

Inconsolata is a variable font that offers a continuous range of widths from 50% to 200%.
Anek Malayalam is a variable google font that supports widths from 75% to 125%. Values below and above this range select the closest matching font.

Providing a font-stretch fallback

Because font-width does not yet have broad browser support, you may want to include the legacy {{cssxref("font-stretch")}} property as a fallback. Place font-stretch before font-width so that supporting browsers use the modern property:

css

p {
  font-stretch: condensed; /* for browsers that don't support font-width */
  font-width: condensed;
}

[!NOTE] You can automate this fallback pattern using the postcss-preset-env plugin for PostCSS, which includes the postcss-font-width-property transform to convert font-width properties to font-stretch automatically.
