Thank you for your question. The Planck Length is a theoretical number at which scale quantum gravity should become apparent. To date, there is no good theory for quantum gravity. However more important, at the quantum physics level, the concept of "size" breaks down. Quantum mechanics, at it's heart, is a probablistic theory. A particle is defined by its wavefunction. The confines of that wavefunction can be expressed in terms of its Compton wavelength. So the answer is probably "no", but until a theory of quantum gravity emerges, we cannot say with certainty... if then. http://math.ucr.edu/home/baez/planck/node2.html http://math.ucr.edu/home/baez/lengths.html http://en.wikipedia.org/wiki/Particle_in_a_box
