An apparatus for determining the length and swing weight of a golf club having a shaft and a head, the head having a sole, there being a top at the end of the shaft remote from the head comprising a longitudinally lengthwise elongated frame; first structure on the frame for supporting the club shaft to extend generally longitudinally; second structure on the frame to contact the shaft top at a first locus and to contact the head sole at a second locus, whereby the club length "1" can be measured between the first and second loci; and third structure adjustably movable relative to the frame to support the shaft at a third locus proximate the determinate center of gravity of the golf club.
