Your connection to the golf club begins and ends with the grip, and its size can have a surprisingly large impact on how you swing a club. While most golfers play with the standard-size grips that come with their clubs, many could find more consistency, power, and comfort by simply making a change. This guide will break down the tangible benefits of using thicker, midsize, or jumbo grips, helping you understand how they work and figure out if they’re the right choice for your game.
How Grip Size Influences Your Swing
Think of your grip as the steering wheel of your golf club. As the provided philosophy states, the hold is "unbelievably important. It is the steering wheel of your golf shots." The way your hands connect to that steering wheel dictates how efficiently you can control the clubface. A standard or undersized grip allows for, and often encourages, a great deal of hand and wrist action. For some highly skilled players, this is desirable, but for most amateurs, it’s a direct line to inconsistency.
When we talk about grip size, we’re generally referring to four main categories:
- Undersize/Ladies: Thinner than the standard measurement.
- Standard: The default on most men’s clubs.
- Midsize: The first step up in thickness.
- Jumbo (or Oversize): The thickest grips available off the shelf.
While the technical measurement differences are in fractions of an inch, the change in how a grip feels and performs can be dramatic. The main purpose of a thicker grip is to alter the relationship between your hands and the club, often in a way that simplifies the swing.
Benefit #1: Reduces Grip Pressure and Tension
The ‘Death Grip’ Problem
One of the most common issues I see as a coach is golfers strangling the club. When you stand over a difficult shot or feel the pressure of a match, the instinct is to tense up and hold on for dear life. This "death grip" does more than just make your knuckles white. It sends tension shooting up through your forearms, into your biceps, up to your shoulders, and across your back.
When those muscles are tight, your ability to make a fluid, powerful, rotational swing is severely limited. Remember, the golf swing is a "rotational action… mainly powered from your body." If your arms and shoulders are locked up with tension, your body can’t turn freely. You lose a feeling of fluidity and end up making a short, jerky, and weak swing that relies solely on your arms.
How Thicker Grips Foster a Softer Hold
A thicker golf grip helps solve this problem by its very nature. It has a larger diameter, which means it fills your hands more completely without you needing to clench down. Think about the difference between holding a skinny pencil versus holding a thick magic marker. You can control the marker with far less finger pressure because its size provides stability.
The same principle applies to your golf grip. By filling the palm and fingers more naturally, a midsize or jumbo grip encourages a lighter, more relaxed hold. This softness in the hands creates a chain reaction in reverse: relaxed hands lead to relaxed forearms and freer shoulders, allowing your torso to rotate properly. This enables the correct sequence of movement and lets you generate speed from your body’s rotation, not from a tense, forceful arm swing.
Benefit #2: Quiets Overactive Hands and Wrists
The Source of Slices and Hooks
For a huge number of amateur golfers, the root cause of an ugly slice or a crippling hook isn't a major swing plane issue - it's overactive hands. Many players instinctively try to steer or "save" the shot at the moment of impact by flicking their wrists or aggressively rolling their hands over. A standard-sized grip provides the perfect platform for this kind of manipulation.
For example, a hook often occurs when the hands roll over too quickly through impact, shutting the clubface down. A slice can be the result of the opposite, where the hands fail to release and the clubface remains wide open. Trying to consciously time this fraction-of-a-second wrist movement under pressure is an incredibly difficult task.
Promoting a More 'Body-Driven' Swing
Thicker grips are a fantastic tool for taking the hands out of the equation. By restricting the small, twitchy muscles in your hands and wrists from dominating the action, a larger grip forces the big muscles to take over. It encourages a swing where your arms, chest, and hips turn through the ball together as a single, connected unit.
Instead of "flipping" at the ball, you learn to rotate your body to deliver the club. This is the very essence of a reliable, repeatable swing.
- For the hooker: A thicker grip physically slows down the rate at which you can close the clubface. This gives the body time to get through the shot, preventing the club from snapping shut too early.
- For the slicer: While it might seem counterintuitive to slow the hands down, a slice is often a reaction to a path that comes over the top. By quieting the hands and promoting a better body turn, a thicker grip can help get the club on a more neutral path, reducing the destructive sidespin.
Benefit #3: Increased Comfort for Certain Players
Golfers with Larger Hands
This is the most straightforward reason to try thicker grips. If you wear M/L, Large, or XL golf gloves, a standard grip is almost certainly too small for you. When you hold a grip that's too thin, your fingers wrap too far around and can end up digging into the fleshy part of your thumb pad. This is uncomfortable and forces you into an unnatural-feeling and inefficient position.
A grip that is sized correctly allows your fingers to close comfortably without overlapping or digging in, giving you much better control without the discomfort.
Players with Arthritis or Joint Pain
Golf should be a game you can play for life, but for many senior players or those suffering from arthritis, the simple act of holding a club can be painful. The constant pressure on finger and hand joints can become a real deterrent.
Jumbo grips, especially those made from softer, more vibration-dampening materials, can make a world of difference. The larger diameter means you don’t have to close your hands as much, reducing strain on the joints. The softer material also absorbs more of the shock from impact, minimizing the jarring vibrations that travel up the shaft and into your hands and elbows.
How to Know if Thicker Grips Are Right for You
Convinced that there might be something to this? Here’s a simple process to figure out if you should make the switch without committing your entire set of clubs.
Step 1: The Simple Finger Test
Take your normal grip on one of your clubs (with your golf glove on). Now look at the middle and ring fingers of your top hand (the left hand for a right-handed golfer). Do these fingers dig deeply into your thumb pad? If so, your grip is very likely too small for your hands. Ideally, those two fingers should just be lightly touching or resting gently against the thumb pad.
Step 2: Start with One Club
Never regrip your entire set at once. The feel will be very different, and it's best to ease into it. Go to a club repair shop and have them put a midsize or jumbo grip on just one of your irons - your 7-iron is usually a great choice since you hit it frequently.
If you want an even lower-cost experiment, ask the shop to add three or four extra layers of grip tape under your existing grip. This will build up the size and simulate the feel of a midsize grip.
Step 3: Test and Observe
Take your newly gripped club to the driving range. Don't judge it after just three swings. Hit at least 20-30 balls and pay close attention to:
- Ball Flight: Is your common miss (hook or slice) disappearing or getting less severe?
- Tension: Do your hands and arms feel more relaxed at setup and throughout the swing?
- Comfort: How does it feel in your hands? Does it feel more stable and secure?
Remember that it might feel weird at first - as stated in the philosophy guide, the hold "is unlike anything else... and it does feel bizarre." Give it a fair chance. You might find that a simple, inexpensive grip change is the straightforward fix you've been looking for.
Final Thoughts
To sum it up, moving to a thicker grip can deliver real benefits by reducing tension, promoting a more powerful body-driven swing, and providing greater comfort. For golfers who struggle with overactive hands, hooks or slices, or hand pain, it’s a simple change that can produce significant improvements in consistency and overall enjoyment.
