Switching to thicker grips on your golf clubs can have a surprisingly powerful effect on your ball striking, but it's not a change you should make without understanding the consequences. This is a deliberate equipment adjustment that directly influences the mechanics of your golf swing, for better or for worse. In this guide, we'll walk through exactly what thicker grips do, who they can help, who they might hurt, and how you can test the theory for yourself without spending a dime on new grips.
To understand the high-level impact of thicker grips, think about holding a pencil versus holding a baseball bat. It’s far easier to manipulate and “flick” the pencil with your fingers and wrists. The baseball bat, however, forces you to use your larger muscles - your hands, arms, and shoulders - to move it. This is the exact principle at play with golf grips.
Your golf swing is ideally a rotational action powered by your bigger muscles (your torso and hips), with your arms and hands along for the ride. However, for many amateur golfers, overly active hands and wrists get involved at the wrong time, trying to "help" the club hit the ball. This is often where things go wrong, leading to inconsistency and common misses like hooks and pulls.
A standard or undersized grip allows for maximum dexterity and an easy, full release of the clubhead through impact. This is great if you have a well-timed swing, but it can also promote that "flippy" or "handsy" action if your timing is off.
A thicker grip (midsize or jumbo) fills more space in your hands, which naturally restricts the small muscles in your fingers and wrists from taking over. It effectively "quiets" your hands, forcing you to power the swing with the rotation of your body. It serves as a mechanical governor on your hands, encouraging a more connected, body-driven swing.
Knowing that thicker grips quiet the hands, we can see who stands to gain the most from making the switch. Golfers who try thicker grips are typically looking for solutions to one of the following issues.
This is the number one reason many golfers experiment with oversized grips. A hook (a shot that curves sharply from right-to-left for a right-handed player) is often caused by an overactive bottom hand (the right hand for righties) that causes the clubface to shut too quickly through impact. The hands get "flippy," closing the face and sending the ball left.
By fitting a thicker grip, you inhibit the ability of that lower hand to rotate over so aggressively. Because it's harder to twist the club, the clubface is more likely to stay square to the target through the hitting zone. This small change can immediately straighten out a persistent hook, turning it into a gentle draw or a straight shot.
The best golfers power their swing with their body, not their arms. I often tell my students that we want to create a swing that is a "rotational action of the golf club that moves around the body." When your hands are too active, they can become disconnected from this rotation, leading to a weak, "all-arms" swing with inconsistent results.
When you have thicker grips, your hands take more of a passive role. You almost have no choice but to engage your torso to get the club moving. This promotes that feeling of the hands, arms, chest, and hips all turning together through the impact zone - a mark of a powerful and repeatable golf swing. For players struggling to get away from lifting and swinging only with their arms, thicker grips can be a tremendous training aid for feeling what a connected, body-powered release feels like.
For some golfers, the benefit is purely about comfort. This is especially true for players with:
Less tension is always a good thing in the golf swing. A light, pressure-free grip allows for a smooth takeaway and effortless speed. If a thicker grip is what allows you to hold the club without a "death grip," it will positively impact every other part of your swing.
Of course, there is no single solution in golf that works for everyone. While thick grips can be great for some, they can be a serious detriment for others.
Remember how a thicker grip restricts the hands from closing the clubface? This is a great thing if you're closing it too much (hooking), but it's a disaster if you already struggle to close it enough. Players who slice the ball (a left-to-right curve for right-handers) often have the opposite problem - their clubface is open at impact. A thicker grip can exacerbate this issue, making it even harder to square the clubface. This can turn a manageable slice into an unplayable block that shoots dead right off the clubface.
While taking the hands out of the full swing is often beneficial, it can be a problem around the greens. Delicate chip and pitch shots rely heavily on the sensitive touch and feel in your fingertips. Some players find that jumbo grips deaden this sensation, making it difficult to judge distance and control the subtle nuances of short game shots. This doesn't happen to everyone, but if you value a high degree of touch and feel in your scoring clubs, you might find thick grips to be a bit clumsy.
So, should you make the change? Before you rush to the pro shop, here’s a simple checklist to run through.
This is the classic pro shop test. No tape measure needed. Hold a club with your normal grip (with your glove on if you wear one).
If you have arthritis, large hands, or hand fatigue, you might benefit from thicker grips for comfort reasons alone, even if the hand measurement test doesn't strongly indicate you need them.
Instead of immediately paying to regrip all 13 of your clubs, you can simulate the feel of a larger grip cheaply. Grab your 7-iron and some athletic tape or electrical tape.
Start wrapping the tape around your existing grip, building it up layer by layer. There is a general rule of thumb for this:
Take it to the range and hit 15-20 balls. How does it feel? Pay close attention to your ball flight. Are your hooks starting to straighten out? Does your miss to the right get worse? Does the decreased tension lead to a feeling of more freedom in your swing? This simple, five-minute experiment will tell you almost everything you need to know about whether thicker grips will work for you.
Thicker golf grips are not a magic bullet, but they are a powerful tool for change if your swing has specific tendencies. For golfers who fight a hook, suffer from hand tension, or have larger hands or arthritis, moving to a midsize or jumbo grip can offer immediate relief and lead to a more consistent, body-driven golf swing.
Trying to navigate equipment choices like this on your own can be confusing, but you don't have to guess.
