Rich cards combine elements into a single message – they must include an image or a video and can also include a title text, description and up to 2 suggested replies and/or actions. Up to 10 Rich Cards can be sent together to create a carousel of options, but cards can be sent standalone as well - you don’t need a carousel.

Aspect ratio/limitations when using media in rich cards

Rich cards can be driven by image size. Google provides the following recommendations for how to best use media in rich cards:

Cards expand vertically to fit their contents. Rich cards have a minimum height of 112 DP and a maximum height of 344 DP. If the contents of a card are not large enough to fill the minimum card height, the card expands and fills the extra height with white space.
Media in rich cards must fit one of three heights:
- Short: 112 DP
- Medium: 168 DP
- Tall: 264 DP.
Vertical rich cards - Vertical rich cards display horizontal media at the top of the card. Horizontal media should have an aspect ratio of 2:1, 16:9, or 7:3.
When you send media to a user, you should be respectful of the user's resources. When horizontal media has a 2:1 ratio, the optimal resolution for the media is 1440x720 px with a maximum recommended file size of 2 MB for images and 10 MB for video. The optimal resolution for the media's thumbnail is 770x335 px with a recommended file size of 40 kB and a recommended maximum size of 100 kB.
