Android Resolution 별 Screen size

Android devices come with a wide range of screen sizes, from 2.8-inch tiny smartphones to 46-inch Google TVs. Android divides these into four categories, based on physical screen size and the distance at which they are usually viewed:


  • Small: Under 3 inches (7.5 cm), at least 426X320dp resolution
  • Normal: 3 inches (7.5 cm) to around 4.5 inches (11.5 cm), at least 470X320dp resolution
  • Large: 4.5 inches (11.5 cm) to around 10 inches (25 cm), at least 640X480dp resolution
  • Extra-large: Over 10 inches (25 cm), at least 960X720dp resolution

By default, your application will not support small screens, will support normal screens,
and may support large and extra-large screens via some code built into Android that
automates conversion, scaling, and resizing of an application onto larger screens.
