The structure of generalized parton distributions is determined from light-front holographic QCD up to a universal reparametrization function
w(x) which incorporates Regge behavior at small
x and inclusive counting rules at
. A simple ansatz for
w(x) which fulfills these physics constraints with a single-parameter results in precise descriptions of both the nucleon and the pion
