A parametrization based on geometric concepts is proposed for the spin-independent part of the amplitude {ital A}{sub 12}({ital s},{ital t}) for elastic scattering of hadrons 1 and 2 at center-of-mass energies {radical}{ital s} {approx gt}20 GeV. The dependence on the squared momentum transfer {ital t} is described by the form factors {ital F}{sub {ital i}}({ital t},{ital R}{sub {ital i}}{sup 2}({ital s})) for each hadron and contain energy-dependent complex radii {ital R}{sub {ital i}}({ital s}). Data on differential cross sections for {ital pp}, {ital p{bar p}}, and {pi}{ital p} as well as the energy dependence of the total cross section and the slope parameter are reproduced with few adjustable parameters. When our parametrization for {ital A}{sub 12}({ital s},{ital t}) is compared to the one from the Pomeron approach strong similarities emerge.
