Getting the Screen Size
screen.availHeight; // returns screen height in pixels screen.availWidth; // returns screen width in pixels

The screen sizes of browsers vary so much that you often need to use different sets of code for larger, medium, or smaller screens. To get the screen size, use the screen.availHeight and screen.availWidth attributes. These values are specified in the number of pixels.
