A scripting approach

        if( typeof( window.innerWidth ) == 'number' ) {
          //Non-IE
          myWidth = window.innerWidth;
          myHeight = window.innerHeight;
        } else if( document.documentElement &&
          ( document.documentElement.clientWidth ||
          document.documentElement.clientHeight ) ) {
          //IE 6+ in 'standards compliant mode'
          myWidth = document.documentElement.clientWidth;
          myHeight = document.documentElement.clientHeight;
        }

The jQuery approach
       // returns width of browser viewport
       $(window).width();
       // returns height of browser viewport
       $(window).height();

       // returns width of HTML document
       $(document).width();
       // returns height of HTML document
       $(document).height();
