App icons
While app icons follow the same usage conventions as IBM UI icons when used in product and web platforms, there are differences when they are used in native OS applications and app store environments. Check the gallery of existing app icons when designing a new one to avoid confusion from similarities with those icons already in use.
Sizing
For productive use in product, app icons work best in four sizes: 16px, 20px, 24px, and 32px. For expressive use, 48px and above may be used. Use icons at their original sizes or scale at accepted increments.
Icon size | Stroke width | Padding | Live area | Corner radius |
---|---|---|---|---|
16px | 1px | 1px | 14px | 1px |
20px | 1.25px | 1.25px | 17.5px | 1.25px |
24px | 1.5px | 1.5px | 21px | 1.5px |
32px | 2px | 2px | 28px | 2px |
48px | 3px | 3px | 42px | 3px |
64px | 4px | 4px | 56px | 4px |
80px | 5px | 5px | 70px | 5px |
96px | 6px | 6px | 84px | 6px |
Alignment
App icons are optically aligned to the center of the icon grid within the boundary box. Centering ensures all icons will be aligned correctly when exported and used side by side.
Containers
App icons can be represented in a circular or rectangular container calculated based on the padding size.
Containers for Native OS
Icons for native applications appear within a variety of contexts, such as task bars, user-customized wallpapers, notifications, system preferences, and more. In most systems, a background container shape is needed to provide proper contrast against the large variety of backgrounds. Check the requirements of the operating system on which your product will be published to determine whether your icon needs a container shape.
Android adaptive icons
Android app icons have user-customizable masks as container shapes and make use of foreground and background layers to achieve parallax effects. You can separate your icon’s elements into the two layers to make use of this feature.
Clearance
When designing with app icons, all artwork should include minimum padding based on 1/4 of the scaled icon grid size. The padding can be increased by increments of 1/4 grid units.
Color
App icons are created in four themes: dark theme, light theme, monochromatic dark theme, and monochromatic light theme. To ensure accessibility, use the color theme that corresponds with the icon’s background color.
Background color value | Icon theme |
---|---|
White, 10–20 | Light theme |
30–50 | Monochromatic light theme (black) |
50–80 | Monochromatic dark theme (white) |
90–100, black | Dark theme |
Monochromatic icons
In some limited use cases, you may need a single-color app icon. These icons are generally used when the icon needs to appear on a color background or in situations when the icon shouldn’t call attention to itself with color, such as disabled states.
Icon versus logo usage
App icons are not logos. It should be clear that any communication featuring an app icon is coming from one of our hero brands or the master IBM brand, never the product itself. Avoid using app icons in ways that convey the product as a brand.
