You are trying to do wrong thing. You need to develop the design not bound to any screen size from the very beginning, one for wide range of sizes. Perhaps you need to embrace
liquid,
fluid or
elastic design. Please see my past answers:
Webpage screen resolution (Cross Browser\Cross Platform) problem[

To Get Screen resolution[

By the way, if you simply use very basic HTML elements, such as
p
,
h1
,
em
, etc., you will immediately get fluid design. So think about it: do some more complicated trick worth effort, if you loose this valuable and basic quality?
