Typography
Material Design's text sizes and styles were developed to balance content density and reading comfort under typical usage conditions.
MDC Typography is a foundational module that applies these styles to MDC Web components. The typographic styles in this module are derived from thirteen styles:
- Headline 1
- Headline 2
- Headline 3
- Headline 4
- Headline 5
- Headline 6
- Subtitle 1
- Subtitle 2
- Body 1
- Body 2
- Caption
- Button
- Overline
Design & API Documentation
Installation

xxxxxxxxxx
<head>
<link href="https://fonts.googleapis.com/css?family=Roboto:300,400,500" rel="stylesheet">
</head>
<body class="mdc-typography">
<h1 class="mdc-typography--headline1">Big header</h1>
</body>

Style Customization
Typography styles
The typography styles (referred to as <STYLE> below) used in the type system:
Scale | Description |
---|---|
headline1 | The largest text on the screen, reserved for short, important text or numerals |
headline2 | Headline variant 2 |
headline3 | Headline variant 3 |
headline4 | Headline variant 4 |
headline5 | Headline variant 5 |
headline6 | Headline variant 6 |
subtitle1 | Smaller than headline, reserved for medium-emphasis text that is shorter in length |
subtitle2 | Subtitle variant 2 |
body1 | Used for long-form writing |
body2 | Body variant 2 |
caption | Used sparingly to annotate imagery |
button | A call to action used by different types of buttons |
overline | Used sparingly to introduce a headline |
CSS Classes
Some components have a set typographic style. For example, a raised MDC Card uses Body 1, Body 2, and Headline styles.
If you want to set the typographic style of an element, which is not a Material Design component, you can apply the following CSS classes.
CSS Class | Description |
---|---|
mdc-typography | Sets the font to Roboto |
mdc-typography--<STYLE> | Sets font properties as STYLE. Please see |
For example, the headline1 style as a CSS class would be mdc-typography--headline1.
CSS Custom Properties
CSS Custom property | Description |
---|---|
--mdc-typography-font-family | The base font-family |
--mdc-typography-<STYLE>-font-family | The font-family for STYLE. Please see |
--mdc-typography-<STYLE>-font-size | The font-size for STYLE. Please see |
--mdc-typography-<STYLE>-line-height | The line-height for STYLE. Please see |
--mdc-typography-<STYLE>-font-weight | The font-weight for STYLE. Please see |
--mdc-typography-<STYLE>-letter-spacing | The letter-spacing for STYLE. Please see |
--mdc-typography-<STYLE>-text-decoration | The text-decoration for STYLE. Please see |
--mdc-typography-<STYLE>-text-transform | The text-transform for STYLE. Please see |
Sass Variables and Mixins
Mixin | Description |
---|---|
base | Sets the font to Roboto |
typography($style) | Applies one of the typography styles, including setting the font to Roboto |
smooth-font | Adds antialiasing for typography |
overflow-ellipsis | Truncates overflow text to one line with an ellipsis |
baseline($top, $bottom, $display) | Sets a container's baseline that text content will align to. |
zero-width-prefix | Adds an invisible, zero-width prefix to a container's text. This ensures that the baseline is always where the text would be, instead of defaulting to the container bottom when text is empty. Do not use this mixin if the baseline mixin is already applied. |
text-baseline($top, $bottom, $display) | Sets the baseline of flow text content. |
A note about overflow-ellipsis, overflow-ellipsis should only be used if the element is display: block or display: inline-block.
$style Values
These styles can be used as the $style argument for the mdc-typography mixin.
- headline1
- headline2
- headline3
- headline4
- headline5
- headline6
- subtitle1
- subtitle2
- body1

Overriding Styles
All styles can be overridden using CSS custom properties or Sass module/global variables.
When using Sass module variables, the module must be configured before any other @use statements with a variable named $styles-{style}. The variable should be assigned to a map that contains all the properties you want to override for a particular style.
When using Sass global variables, they must be defined before the component is imported by setting a global variable named $mdc-typography-styles-{style}.
Example: Overriding the button font-size and text-transform properties.
CSS custom properties:
xxxxxxxxxx
html {
--mdc-typography-button-font-size: 16px;
--mdc-typography-button-text-transform: none;
}
Sass module variables:
@use "@material/typography" with (
$styles-button: (
font-size: 16px,
text-transform: none,
)
);
@use "@material/button";
@include button.core-styles;
Sass global variables:
xxxxxxxxxx
$mdc-typography-styles-button: (
font-size: 16px,
text-transform: none,
);
@import "@material/button/mdc-button";
Example: Overriding the global font-family property.
CSS custom properties:
xxxxxxxxxx
html {
--mdc-typography-font-family: Arial, Helvetica, sans-serif;
}
Sass module variables:
xxxxxxxxxx
@use "@material/typography" with (
$font-family: unquote("Arial, Helvetica, sans-serif")
);
@use "@material/button";
@include button.core-styles;
Sass global variables:
xxxxxxxxxx
$mdc-typography-font-family: unquote("Arial, Helvetica, sans-serif");
@import "@material/button/mdc-button";
Example: Overriding the font-family property for headline1 and font-family and font-size for headline2.
CSS custom properties:
xxxxxxxxxx
html {
--mdc-typography-headline1-font-family: Arial, Helvetica, sans-serif;
--mdc-typography-headline2-font-family: Arial, Helvetica, sans-serif;
--mdc-typography-headline2-font-size: 3.25rem;
}
Sass module variables:
xxxxxxxxxx
@use "@material/typography" with (
$styles-headline1: (
font-family: unquote("Arial, Helvetica, sans-serif")
),
$styles-headline2: (
font-family: unquote("Arial, Helvetica, sans-serif"),
font-size: 3.25rem
)
);
@use ...
Sass global variables:
xxxxxxxxxx
$mdc-typography-styles-headline1: (
font-family: unquote("Arial, Helvetica, sans-serif")
);
$mdc-typography-styles-headline2: (
font-family: unquote("Arial, Helvetica, sans-serif"),
font-size: 3.25rem
);
@import ...
