How fast do wave packets typically spread out?

  1. Feb 25, 2012 #1
    Do the wave functions for smaller objects disperse faster?

    How long does a macroscopic wave function (for example that corresponding to a measurement device) keep its broadness (roughly speaking)?

    Context: I'm reading a paper where they rely on the claim
    and I would have no clue about this, hence this post.
