Mobile Display Resolution

Because each manufacturer creates its own displays, there are no clear standard screen resolutions for mobile devices the way there are for computer monitors. But to get you in the ballpark, take a look at some current specifications. On the low end are standard mobile phones with screen dimensions of 128 × 128 pixels. Fuller-featured phones typically have resolutions of 176 × 208, 176 × 220, 208 × 208, or as large as 240 × 320. Handheld devices, such as the ubiquitous BlackBerry, sport screen sizes of 240 × 160 or 240 × 240.
