The success of Android as a mobile device Operating System (OS) has resulted in a large variety of screen sizes and resolutions. Here is provided a list of example devices to show that variation.
In the following table it is assumed that the device is held in portrait orientation. As such the width in pixels is the X-axis and the length or height in pixels is the Y-axis. Obviously that swaps when the device is held in landscape orientation. Android has support for both orientations so that a correctly programmed App will work no matter which way you hold the device. If you need to understand about pixels see the article How Computer Screens and Printers Show Images. The total number of pixels in a screen is the number in the x-axis multiplied by the number in the y-axis. The more pixels for each square inch (or centimetre) of display the sharper any images will be displayed (provided those images are at a high resolution).
For an explanation of the Acronym see the article Screen Resolution Names. The Size column next to each device is the diagonal measurement for the device screen in inches. This table illustrates that screens with the same resolution can be different sizes.

The iPhone 4S is shown in the table for comparision purposes, see the DVGA line, it is not an Android phone. Note a Full High Definition (FHD) or 1080i/1080p screen is 1080×1920 which is 2,073,600 pixels. Despite the wide variation in resolutions and screen sizes the Android OS and its Software Development Kit (SDK) caters for all of them.
