[jQuery] Get dynamic width

[eewan]

Hello,
I want to find full width of all elements in one div. Here is example
code:
<div id="scroller">
<p>text</p>
<p>text</p>
<p>text</p>
<p>text</p>
</div>


$("#scroller p").each(
function(i){
var elSize = $(this).width();});

I need total width of all <p> :-)

Thanks in advance
