This is how I would do it (tested in FF/Chrome):

<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript">
function autoResize(iframe) {
    $(iframe).height($(iframe).contents().find('html').height());
}
</script>

<iframe src="page.html" width="100%" height="100" marginheight="0" frameborder="0" onload="autoResize(this);"></iframe>

Javascript to be placed in header:

function resizeIframe(obj) {
        obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
      }

Here goes iframe html code:

<iframe class="spec_iframe" seamless="seamless" frameborder="0" scrolling="no" id="iframe" onload="javascript:resizeIframe(this);" src="somepage.php" style="height: 1726px;"></iframe>

Css stylesheet

.spec_iframe {
        width: 100%;
        overflow: hidden;
    }

I know the post is old, but I believe this is yet another way to do it. I just implemented on my code. Works perfectly both on page load and on page resize:

var videoHeight;
var videoWidth;
var iframeHeight;
var iframeWidth;

function resizeIframe(){
    videoHeight = $('.video-container').height();//iframe parent div's height
    videoWidth = $('.video-container').width();//iframe parent div's width

    iframeHeight = $('.youtubeFrames').height(videoHeight);//iframe's height
    iframeWidth = $('.youtubeFrames').width(videoWidth);//iframe's width
}
resizeIframe();


$(window).on('resize', function(){
    resizeIframe();
});

Here are several methods:

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="http://www.example.com" frameborder="0" style="overflow:hidden;height:100%;width:100%" height="100%" width="100%"></iframe>
</body>

AND ANOTHER ALTERNATIVE

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="http://www.example.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:100%;width:100%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" height="100%" width="100%"></iframe>
</body>

TO HIDE SCROLLING WITH 2 ALTERNATIVES AS SHOWN ABOVE

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="http://www.example.com" frameborder="0" style="overflow:hidden;height:150%;width:150%" height="150%" width="150%"></iframe>
</body>

HACK WITH SECOND CODE

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="http://www.example.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:150%;width:150%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" height="150%" width="150%"></iframe>
</body>

To hide the scroll-bars of the iFrame, the parent is made "overflow:hidden" to hide scrollbars and the iFrame is made to go upto 150% width and height which forces the scroll-bars outside the page and since the body doesn't have scroll-bars one may not expect the iframe to be exceeding the bounds of the page. This hides the scrollbars of the iFrame with full width!

source: set iframe auto height

Cross-browser jQuery plug-in.

Cross-bowser, cross domain library that uses mutationObserver to keep iFrame sized to the content and postMessage to communicate between iFrame and host page. Works with or without jQuery.
