Grip size is the cheapest specification in golf and one of the few that changes direction. The grip is the only part of the club you touch, and its diameter determines how freely your hands can rotate through impact. Too small tends to encourage an over-active release; too large tends to inhibit it. This guide covers how to measure, what the sizes mean, and why grip weight matters as much as diameter for how the club feels.
01
Grip sizing follows glove size and finger length rather than height. Measure from the wrist crease to the tip of the middle finger, and note whether your fingers are long or short relative to your palm. Long fingers with a small palm and short fingers with a large palm need different answers than glove size alone suggests.
02
Undersize, standard, midsize and jumbo each change diameter in steps, and build-up tape offers finer increments between them. Moving up one step reduces hand action; moving down increases it. A golfer fighting a hook is often over-active with grips a size too small, and a golfer blocking shots right is often over-gripping something too thick.
03
Grips vary meaningfully in weight, and weight added at the butt lowers swing weight — the head feels lighter. Swapping to a much heavier or lighter grip changes the feel of a club that was otherwise correct, so grip changes are best made with swing weight in mind.
04
A correctly-sized grip that has hardened is worse than a slightly wrong one that is fresh, because hardened rubber makes you hold on tighter, and grip pressure changes tempo and release. Regular players should re-grip roughly annually.
