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.

Keyline Shapes




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
A system icon, or UI icon, symbolizes a command, file, device, or directory. System icons are also used to represent common actions like trash, print, and save.
Within the 24dp bounding box, square icons are 18x18dp, circles are 20dp, and rectangles are 20dp on their longest side.
