var height = $('#myElement').innerHeight(); Edit: Use jQuery's outerHeight function to get the calculated height of an element, including padding, border and optionally the margin.
//without margin var height = $('#myElement').outerHeight(); //with margin var height = $('#myElement').outerHeight(true); Edit 2: You may also compare these results with native Javascript.
var el = document.getElementById('myElement'); var height = el.offsetHeight;
