The stringing system is for use with racquets, having parallel longitudinal strings, and parallel cross strings, which pass alternately over and under the longitudinal strings. Initially, the longitudinal strings are tensioned, and the cross strings are then inserted and tensioned. The longitudinal strings are tensioned, using a force, which depends upon the length of the longest string between racquet head and frame. The force increases with increased length. The cross strings are tensioned using a force, dependent upon the length of the longest cross strings, and length of the tension force of the longest longitudinal string, generating an even force, which increases with increasing length of the cross strings.
