Types and sizes
BlackBerry smartphones use different sizes for in-app icons and indicators.
Keep the main graphical elements within the inner area of the icon or indicator to allow for a UI buffer zone. The focal area refers to the size of the symbol within the icon itself.
Action bar and menu icons
8 x 8 du (focal area 5.5 x 5.5 du)
Large icons are the most common. Apps use them most often in these UI contexts:
Action bar with tab icons
Action menu icons
Tab menu icons
Content area icons
Application menu icons
Context menu icons
Components and small buttons
Use the medium icon size for components.
7 x 7 du (focal area 4.5 x 4.5 du).
Use the small icon size for small buttons.
6 x 6 du (focal area 4.5 x 4.5 du)
Indicators are small icons used in the content area to show extra information (for example, status). If you create an indicator, follow the design guidelines for icons listed above. Reduce the amount of detail, and reduce the number of pixels by one for the largest lines. Follow the size and alignment guidelines below:
5 x 4 du
3 x 3 du
Recommended: Make indicators smaller than the adjacent text. Bottom-align indicators to the baseline.
Not recommended: The first indicator is not bottom-aligned. The second indicator is larger than the text.
