I stumbled upon this nice link showing the universe at different scales: http://htwins.net/scale2/
However, if you scroll down to the attometer scale you get to the elementary particles which have been given sizes. Does anyone know what these sizes mean? I thought elementary particles were dimensionless and so have no strict size.

I'd guess it either refers to something similar to a "classical electron radius" or it uses their wavefunction to determine the volume of space they are likely to occupy and base the size on that.
