Image Sizing Guidance

To minimize scaling artifacts across a wide range of car screens, apps should provide images targeting a 480 x 480 dp bounding box. If the image exceeds this maximum size in either one of the dimensions, it will be scaled down to be centered inside the bounding box while preserving its aspect ratio.
