Probbaly not what you want but you can set it.

<input type="textbox" style="width:100px" >

right, and i'm aware of that... how would you then--ever--be able to
determine the height of an object on a page?? not even when a stylesheet
style is set does it seem to work?!

ANY ideas???

This works in my IE 6, Netscape 7.2, Firefox 1.0

function showwidth(){
t=document.getElementById('txt1');
alert(t.offsetWidth);
}

<input type="textbox" id="txt1" value="what's my width?">

Did you try this approach:

d=document.getElementById(objectID);
alert(d.offsetHeight);

The first 2 links show browser support:

<form action="">
<input type="textbox" id="myTxt" value="what's my width?"
onClick="
var msg;
var elem = this;

// IE method
if (elem.currentStyle) {
msg = elem.currentStyle['width'];

// W3C method
} else if (window.getComputedStyle) {
var compStyle = window.getComputedStyle(elem, '');
msg = compStyle.getPropertyValue('width');
} else {
msg = 'The methods I tried ain\'t '
+ 'supported by your browser.';
}

alert(msg)">
</form>

However, you will notice that IE very helpfully returns "auto" if
you haven't specified a width. Firefox gives a response in px.

Google for "JavaScript 1.5 reference" and you'll find lots of them.

http://www.programmershelp.co.uk/javascriptref.php
http://www.byteshift.de/javascript-1415/CoreGuideJS15/
http://synchro.net/docs/js/ref/ix.html
http://www.croczilla.com/~alex/refer...avascript_ref/

I learned a LOT (including offsetWidth) from this newsgroup. When I run
into problems I use Google, and search this newsgroup to see if similar
problems have been solved here.

Also, please don't top post, it throws off the Q&A flow.
Good Luck,
Mike
