Application Icons

To ensure that your app icon looks great in all the places that users see it, you need to provide resources in the sizes listed below:

  • 1024x1024
  • 512x512
  • 256x256
  • 128x128
  • 64x64
  • 32x32
  • 16x16


Create icons for standard- and high-resolution displays. You need to supply two resources:

  • 32x32
  • 32x32@2x (64x64)

Use the PNG format.


Create your icons in three sizes:

  • 16x16
  • 18x18
  • 32x32 pixels (if using PDF)
If you create your sidebar icons in PDF format (recommended), OS X will automatically scale your icon for high-resolution display. You do not need to provide high-resolution versions. However, if you use PNG format for your icons, you will need to supply the following resources:
  • 16x16
  • 16x16@2x
  • 18x18
  • 18x18@2x
  • 32x32
  • 32x32@2x

Product Icons

Product icons are the visual expression of a brand’s products, services, and tools. Simple, bold, and friendly, they communicate the core idea and intent of a product. While each product icon is visually distinct, all product icons for a given brand should be unified through concept and execution.

Product icons are an essential vehicle for communicating your brand. Using these guidelines as a starting point, make sure your product icon colors and other key elements reflect your brand identity.

Product Icon Grid

The product icon grid has been developed to facilitate consistency and establish a clear set of rules for the positioning of graphic elements. This standardization results in a flexible but coherent system.

DP Unit Grid

Device launchers display product icons at 48dp. When you create the icon, maintain the 48-unit measure, but scale it to 400% at 192 x 192 px.

By maintaining the unit ratio, you preserve sharp edges and correct alignment when the scale is reduced.

System Icons
