Guidelines Typography


Roboto is used throughout the system for consistency and to help with legibility.

To ensure readability across a wide variety of displays and vehicle layouts, the system UI provides 2 preset font sizes. Use the primary size for all text that is important for making a decision, such as a song name in a playlist. Use the secondary size for text that provides non-critical, supplemental information for decision making, such as the artist name in a playlist.

Text length

To help ensure short glance times, make all text strings concise and brief. Strings should not exceed 120 characters in any language, including spaces and punctuation. Strings that do not fit within their allotted space will be truncated with “...”.


Make all text strings concise and brief.


Displaying long strings of text requires too much attention from the driver.
