Application covers

An application cover appears on the running apps panel on the home screen. Users tap a cover to re-open the application.

To help you decide whether to create a cover for your application, consider the following:

  • Is there a single item that users should know about when the application is minimized (for example, a calendar shows the next event and a weather application shows the current temperature)? If so, create an application cover.
  • Is it more important for users to see the state of the application when it was minimized? If so, you don't need to create an application cover. A scaled-down version of the current application screen displays as the cover.

This screen shows examples of application covers.

Best practices

  • Create an image that is 457 pixels high by 336 pixels wide. A footer appears automatically and includes your application icon and the title of your application. The application icon is scaled down to 40 x 40 pixels. The text appears in Slate Pro font at regular weight and is set to 40 pixels high.
  • If you add text to the main body of the cover, use the Slate Pro font at regular weight and set it to 30 pixels high. Set secondary text to 25 pixels high.
  • If you include a header, make it 63 pixels high. If you include an avatar, make it 50 x 50 pixels. If you include text, use Slate Pro font at regular weight and set it to 25 pixels high.
  • Place the most important information near the top of the cover. Only the top half of the cover appears on BlackBerry smartphones with a physical keyboard.
  • Avoid trying to put too much information on the cover.
