{ Summary} The all-new design of the Golfsmith Grip Sizer is easier to use & makes more accurate measurements. Two measurements ? the palm from the crease of the wrist to the tip of the middle finger & the length of just the middle finger ? added together equal the size of the grip most appropriate for the player's h&. Convenient ruler markings, grip size cutouts & stamped instructions on the sturdy metal tool make the process fast & simple.
