I am not sure under which rubric questions about string theory or M-theory should go. Anyway, since this question concerns sizes down to the Planck distance, I suppose it should go here.
The question is two fold: in such a case as the 6 extra spatial dimensions of string theory, how does one precisely define the size of a spatial dimension? Secondly, how does one measure it?
