// Artboard bounds helper (used above):
function getArtboardBounds(artboard) {

  var bounds = artboard.artboardRect,

      left   = bounds[0],
      top    = bounds[1],
      right  = bounds[2],
      bottom = bounds[3],

      width  = right - left,
      height = top - bottom,

      props  = {
        left   : left,
        top    : top,
        width  : width,
        height : height
      };

  return props;
}

function findRequiredScale(props) {
	var scale = Math.min(requiredABsize / props.height, requiredABsize / props.width);
	if (scale >1)
	return scale;
	else
	return 1;
}

change following variable to resize to other dimension!
var requiredABsize = 800; //px

is this script work for scale down?
