Angular Material and changing fonts

You can use the CSS universal selector (*) in your CSS or SCSS:

* {
  font-family: Raleway /* Replace with your custom font */, sans-serif !important; 
  /* Add !important to overwrite all elements */
}

Starting from Angular Material v2.0.0-beta.7, you can customise the typography by creating a typography configuration with the mat-typography-config function and including this config in the angular-material-typography mixin:

@import '~@angular/material/theming';
$custom-typography: mat-typography-config(
  $font-family: 'Raleway'
);

@include angular-material-typography($custom-typography);

Alternatively (v2.0.0-beta.10 and up):

// NOTE: From `2.0.0-beta.10`, you can now pass the typography via the mat-core() mixin:
@import '~@angular/material/theming';
$custom-typography: mat-typography-config(
  $font-family: 'Raleway'
);
@include mat-core($custom-typography);

Refer to Angular Material's typography documentation for more info.


Note: To apply the fonts, add the mat-typography class to the parent where your custom fonts should be applied:

<body class="mat-typography">
  <h1>Hello, world!</h1>
  <!-- ... -->
</body>

From this official guide:

Typography customization is an extension of Angular Material's Sass-based theming. Similar to creating a custom theme, you can create a custom typography configuration.

So, include this line in your index.html file, linking to some external font:

<link href="https://fonts.googleapis.com/css?family=Oswald" rel="stylesheet">

Then put in your styles.scss file the custom typography settings, adjusting the font-family string for the selected font:

@import '~@angular/material/theming';

$custom-typography: mat-typography-config($font-family: '"Oswald", sans-serif;');
@include mat.core($custom-typography);

A full custom theme, with colors and all, is something like:

@import '~@angular/material/theming';

$custom-typography: mat-typography-config($font-family: '"Oswald", sans-serif;');
@include mat.core($custom-typography);

$custom-primary: mat.define-palette($mat-blue);
$custom-accent: mat.define-palette($mat-amber);
$custom-theme: mat.define-light-theme($custom-primary, $custom-accent);
@include mat.all-component-themes($custom-theme);

That's it.

Update:

As commented by @Nate May, it changed with v12, so check the updated documentation about the current recommendation for custom typography.
