A golf club grip system is presented comprised of golf club grips of identical weights regardless of their grip thickness. The identical weight may be maintained by altering the grip material compound, grip construction method, or by varying the length of the grip along the golf club shaft as the grip width is varied.A set of standardized grip widths is also presented that varies in increments of the thickness of duct tape, thus providing a standard method of adjusting the thickness of a golf club grip on a shaft.The system is designed to permit pre-manufactured golf club grips to be selected by grip thickness and feel, while remaining identically weighted to all other possible thicknesses. This uniform weighting removes the need to adjust club head weight or perform dynamic or static swing weighting after grip thickness is selected.
