Here a little code snippet from my own usage of fancybox. I adjusted width and height by percentage.

$(".imagebox").fancybox({
    maxWidth    : 600,
    maxHeight   : 600,
    wrapCSS     : 'fancy-imagebox', // add a class selector to the fancybox wrap
    margin      : [0, 0, 0, 0],
    width       : '70%',
    height      : '90%',
    autoSize    : true
});
