  This paper scrutinizes the dynamical QCD effects influence on mesons, namely,
the mean-square root radius of a pion in the holographic light-front wave
function setup, in the context of the AdS/QCD. The nuclear configurational
entropy, associated to mesonic holographic light-front wave functions, is shown
to have a critical point that optimizes the two parameters of the spin-improved
light-front wave function. The mean-square root pion radius and its
cross-section, computed upon these derived values, match the exact existing
experimental data to the precision of 0.14\%, below the experimental error at
the PDG.
