<DIV dir=ltr align=left><SPAN class=293072619-06012007><FONT face=Arial
color=#0000ff size=2>It's just IE being IE. Other browsers have getComputedStyle
which tells you the dimensions in pixels. IE has currentStyle; although that
does tell you the current style (taking the CSS cascade into effect) it returns
whatever dimensions were given in the style rule. jQuery's .css() method uses
whatever it's dealt by the browser.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=293072619-06012007><FONT face=Arial
color=#0000ff size=2>I think I've seen IE hacks where you can put a box
around a character and then measure the box in pixels to get the font size, but
my Google-fu is weak at the moment.</FONT></SPAN></DIV></BODY></HTML>
