Lattice measurements of spatial distributions of the light quark bilinear densities in static mesons allow to test in detail the wave functions of quark models. These distributions are gauge invariant quantities directly related to the spatial distribution of wave functions. We make a detailed comparison of recent lattice QCD results with relativistic quark models, previously formulated for different purposes. This provides a transparent physical interpretation of the lattice data.
