Particles have measurable sizes. Now you can argue this is a collapsing wavefunction, which I guess it is, but what size does a wavefunction have? I think the general interpretation is that the wavefunction is probability distribution and in that case the electron "cloud" is really the uncertainty about where the electron is not a larger object.
