The Spec That Controls How You Control the Club
When you grip a club with your lead hand correctly, the fingertips of your fingers should barely touch your palm. If the fingertips dig deeply into your palm, the grip is too thin (get midsize or larger). If there's a gap between fingertips and palm, the grip is too thick (get undersize or standard).
A reasonable starting reference: Medium or Small glove → Standard grip. Medium-Large → Standard or Midsize. Large → Midsize. XL → Midsize or Jumbo. These are starting points — hand feel and the fingertip test above are more reliable than glove size alone.
Undersized grip (too thin): encourages more wrist action → more hook/draw tendency, lower ball flight. Oversized grip (too thick): reduces wrist action → more fade tendency, higher ball flight. This effect is why many golfers with chronic hooks benefit from larger grips without changing their swing.
Putter grips are subject to different rules — you can install any size grip on a putter. Many golfers use oversize putter grips (SuperStroke, etc.) to reduce wrist action even if their full-swing grips are standard. Experimenting with putter grip size is low-cost and high-impact for many golfers.
Rubber grips: most common, good feel, moderate durability, various firmness options. Cord grips: woven cord in the rubber for maximum tackiness in wet conditions, firmer feel preferred by many tour pros. Rubber-cord hybrid: best of both. Grips also vary in softness — softer grips provide more feel but wear faster.
Grips should be replaced every 40 rounds or once per year (whichever comes first). Worn grips are slippery, requiring more grip pressure — which creates tension in hands, arms, and shoulders that hurts swing mechanics. New grips are one of the cheapest upgrades in golf ($8-15 per grip, often free with purchase at local shop).
Proper grip size allows your hands to work correctly through the swing — which GOATY's mechanics training optimizes. The correct grip size removes unnecessary tension from your hands and arms, allowing the efficient swing patterns GOATY teaches to express themselves fully.
