In a nonperturbative approach we have made extensive and comprehensive calculations of the processes of vector meson electroproduction. We here confront our results with recent data on the elastic processes of {rho} and {phi} electroproduction. The description is unified for all vector mesons, without free parameters, covering 5 scales of magnitude in cross sections, exhibiting a universality that is determined by properties of the overlap of photon and vector meson wave functions.
