This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The getContentDimensions() method of the HTMLIFrameElement interface retrieves the X and Y dimensions of the content window.

Note: The values returned are equivalent to document.body.scrollWidth and document.body.scrollHeight.


var instanceOfDOMRequest =


A DOMRequest for handling the dimensions request. Its request.onsuccess handler handles the success case, and its request.onerror handler handles the failure case.

The X and Y dimensions are available in the request.result.x and request.result.y properties, respectively.




var browser = document.querySelector('iframe');

var request = browser.getContentDimensions();

request.onsuccess = function() {
  console.log("page size:", request.result.width + "x"
              + request.result.height);

request.onerror = function() {
  console.log("Download error");
