This paper reports that unitary bounds for the differential cross-section of high-energy elastic hadron-hadron scattering are obtained under the constraints of fixed total cross-section {sigma}{sub t}, elasticity x, real part to imaginary part ratio {rho} of the forward scattering amplitude, and forward slope b by assuming a finite interaction range. The obtained upper bound has an observed curvature structure at small momentum transfers and is nearly saturated by the experimental data of pp and {bar p}p scattering at {minus} t = 0-0.3 (GeV/c){sup 2} in the energy region sq. root s = 10-1800 GeV, if we take the interaction radius scaled as R{sub 0} {approximately} 0.43 {radical} (1 + {rho}{sup 2}){sigma}{sub t/x}.
