What factor most influences putter loft fitting?

The factor that most influences putter loft fitting is the hands/shaft angle at impact. This angle can significantly affect how the ball is struck at the moment of contact. When a golfer addresses the ball, the position of their hands in relation to the putter shaft determines the effective loft that the putter presents to the ball at impact. If a player's hands are forward or backward at impact, it can change the launch conditions of the ball, influencing how it rolls and its initial trajectory.

Understanding this relationship is crucial because the right loft can help achieve the desired roll and distance control. Proper fitting ensures that the putter’s loft aligns with the golfer's unique stroke mechanics and impact position, ultimately enhancing performance on the greens. Therefore, attention to the hands/shaft angle is key in determining the ideal loft for a putter fit.
