Typography

Use typography to present your design and content as clearly and efficiently as possible.

Too many type sizes and styles at once can spoil any layout. A typographic scale has a limited set of type sizes that work well together along with the layout grid.

General

The Roboto font will not be automatically loaded by Material-UI. The developer is responsible for loading all fonts used in their application. Roboto Font has a few easy ways to get started. For more advanced configuration, check out the theme customization section.

Roboto Font CDN

Shown below is a sample link markup used to load the Roboto font from a CDN:

<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap" />

Install with npm

You can install it by typing the below command in your terminal:

npm install @fontsource/roboto

Then, you can import it in your entry-point.

import '@fontsource/roboto';

For more info check out Fontsource.

⚠️ Be careful when using this approach. Make sure your bundler doesn't eager load all the font variations (100/300/400/500/700/900, italic/regular, SVG/woff). Fontsource can be configured to load specific subsets, weights and styles. Inlining all the font files can significantly increase the size of your bundle. Material-UI default typography configuration only relies on 300, 400, 500, and 700 font weights.

Theme

In some situations you might not be able to use the Typography component. Hopefully, you might be able to take advantage of the typography keys of the theme.

This div's text looks like that of a button.

<div className={classes.root}>{"This div's text looks like that of a button."}</div>

Changing the semantic element

The Typography component uses the variantMapping property to associate a UI variant with a semantic element. It’s important to realize that the style of a typography is independent from the semantic underlying element.

You can change the underlying element for a one time occasion with the component property:

{/* There is already an h1 in the page, let's not duplicate it. */}
<Typography variant="h1" component="h2">
  h1. Heading
</Typography>

You can change the mapping globally using the theme:

const theme = createTheme({
  props: {
    MuiTypography: {
      variantMapping: {
        h1: 'h2',
        h2: 'h2',
        h3: 'h2',
        h4: 'h2',
        h5: 'h2',
        h6: 'h2',
        subtitle1: 'h2',
        subtitle2: 'h2',
        body1: 'span',
        body2: 'span',
      },
    },
  },
});

Accessibility

A few key factors to follow for an accessible typography:

Color. Provide enough contrast between text and its background, check out the minimum recommended WCAG 2.0 color contrast ratio (4.5:1).
Font size. Use relative units (rem) to accommodate the user's settings.
Heading hierarchy. Don't skip heading levels. In order to solve this problem, you need to separate the semantics from the style.
