It sounds like this (the iframe should have a 4:3 ratio) is the thing
you're actually trying to achieve.  This can be done much more easily
than parent-lengths, and without the horrible side-effects.

I have a proposal for an aspect-ratio property on my blog
<http://www.xanthir.com/blog/b4810> that I'm going to try and get into
the Sizing module (most likely, the next level of it), which will
solve your problem.
