We All Know the Script
<script language="javascript" type="text/javascript">
//<!--
function popup()
{ window.open ("YourURLgoesHere.html","popup","width=400,height=400,location=0,menubar=0,resizabl e=0,scrollbars=0,status=0,titlebar=1,toolbar=0") }
-->
</script>


but Is There Any Way Of Finding The Exact Width And Height Of A Page?

Not that i know of... Of course you could always resize the window.
