To calculate height of any element or window or document we can make use of the "height()" method of jQuery.

$(document).ready(function(){  
$("p").append($("p").height()+" px");
$("div.divContainer").append($("div.divContainer").height()+" px");
$("div.document").append($(document).height()+" px");
$("div.window").append($(window).height()+" px");         
});

<div class="document">Height of this document is: </div>
<div class="window">Height of this window is: </div>
<div class="divContainer">Height of this div container is: </div> 
<p>Height of this paragraph is: </p>
