A tool designed to determine the correct diameter for hand placement on a golf club. These aids typically utilize measurements, such as hand size (length and width), to recommend a grip size, often expressed as standard, midsize, or jumbo. The objective is to facilitate a comfortable and controlled hold on the club.
Proper grip dimension is fundamental to consistent and effective swing mechanics. A grip that is too small can lead to excessive hand action and a tendency to hook the ball, while an oversized grip may inhibit wrist hinge and rotation, potentially causing a slice. Historically, golfers relied on trial and error to find the appropriate fit; these tools offer a more precise and personalized starting point, which can improve performance and reduce the risk of injury.
