Android: Screen Densities, Sizes, Configurations, and Icon Sizes

1. Definitions

  • resolution = number of pixels available in the display, scale-independent pixel = sp
  • density = how many pixels appear within a constant area of the display, dots per inch = dpi
  • size = amount of physical space available for displaying an interface, screen's diagonal, inch
  • density-independent pixel = virtual pixel that is independent of the screen density, dp

2. Density Classes

Class Name Density Factor Drawable Folder Comment
ldpi low density 120 dpi sp = 3/4 * dp drawable-ldpi  
mdpi medium density 160 dpi sp = dp drawable-mdpi OR drawable baseline size, example: 320x480 (sp or dp)
hdpi high density 240 dpi sp = 1.5 x dp drawable-hdpi example: 480x800 sp = 320x533 dp
xhdpi extra high density 320 dpi sp = 2 x dp drawable-xhdpi  
xxhdpi extra extra high density 480 dpi sp = 3 x dp drawable-xxhdpi

  • (1) Google documentation says: "Applications should not generally worry about this density; relying on XHIGH graphics being scaled up to it should be sufficient for almost all cases."
  • Launcher icons for Android Market: 512x512 px.
