The relaxation time derived with use of the thickness-dependent thin-film Thomas-Fermi impurity potential in the collision term of the Boltzmann transport equation is used to study the classical size effects in the Hall coefficient $R_f$ and magnetoresistance $M_f$ in metallic thin films. The theoretical prediction of $R_f$ agrees well with experimental results. The dependence of $M_f$ on thickness and magnetic field is also discussed.
