Powered by Google Fonts, the type scale generator is a tool for creating type scales and corresponding code. Any font you choose is automatically resized and optimized based on Material typography guidance for readability.

Select a category in the type scale to view the font’s details. Adjust your font choice through the menus on the right.

This example type scale uses the Roboto typeface for all headlines, subtitles, body, and captions, creating a cohesive typography experience. Hierarchy is communicated through differences in font weight (Light, Medium, Regular), size, letter spacing, and case.

The following units are used to express font size on Android, iOS, and the web.

Example conversions

Web browsers calculate the REM (the root em size) based on the root element size. The default for modern web browsers is 16px, so the conversion is SP_SIZE/16 = rem.

The following units are for spacing letters in a UI.

Letter spacing examples

In the type scale, headlines span from a range of 1 through 6. Headlines are the largest text on the screen, reserved for short, important text or numerals.

For headlines, you can choose an expressive font, such as a display, handwritten, or script style. These unconventional font designs have details and intricacy that help attract the eye.

Serif or sans serif typefaces work well for headlines, especially at smaller sizes.

Subtitles are smaller than headlines. They are typically reserved for medium-emphasis text that is shorter in length. Serif or sans serif typefaces work well for subtitles.

For subtitles, use caution when using expressive fonts, including display, handwritten, and script styles.

Body text comes in ranges 1-2, and it’s typically used for long-form writing as it works well for small text sizes. For longer sections of text, a serif or sans serif typeface is recommended.

Don’t use expressive fonts, including display, handwritten, and script styles for body copy.

Caption and overline text (text with a line above it) are the smallest font sizes. They are used sparingly to annotate imagery or to introduce a headline.

Don’t use expressive fonts, including display, handwritten, and script styles for caption or overline.

Button text is a call to action used by different types of buttons (such as text, outlined and contained buttons) and in tabs, dialogs, and cards.

Button text is typically an all caps sans serif.

Button text can be sentence case, sans serif, or serif.

Don’t use expressive fonts as button text, including display, handwritten, and script styles.
