Notes & Best Practices for Stream Banner Images

Stream banners dynamically resize to adjust to different screen sizes and devices, using the background-size: cover CSS property. This means that they will be stretched or trimmed to fit the width of the screen (if needed). Regardless of whether they are stretched or trimmed, they will always be centered:


As a result, the recommended size above is a general starting point, and not all of the image will be visible on all devices. For best appearance across devices, follow these guidelines:

  • Keep your stream banner images at a ratio of ca. 3:1.
  • If you incorporate logos or key graphics in your banner image, make sure they are centered and no more than 50% of the image's height and 30% of the image's width.
  • If you intend to use a logo in your banner, we suggest leveraging the Banner+Logo logo image option, and applying a more abstract background image (such as a pattern).
