Grip Size
Grip size is the thickness, or diameter, of the rubber grip on a golf club. It determines how the club feels in the hands and runs from slim undersize grips through standard and midsize up to thick oversize (jumbo) grips.
What is grip size?
The grip is the only part of a golf club a player actually touches, so its thickness has a direct say in how the club behaves. Grip size describes that thickness. It is usually measured as the diameter of the grip two inches down from the butt end, the top of the club where the hands sit.
Hands vary enormously. A grip that suits a small-handed junior feels cramped to a player with large palms, so manufacturers make grips in a range of thicknesses and let the club be matched to the hand holding it. When the fit is right, the hands sit naturally and work through the swing without fighting the club.
Size is a separate quality from the grip’s material or texture. Two grips with the same diameter can still feel different in the hand because of the rubber compound or surface pattern, but grip size refers only to the diameter.
The four grip sizes
Golf grips are grouped into four categories, each defined by how its diameter compares to standard. Standard is the baseline that most clubs ship with, and it fits the widest range of adult hands.
| Size | Diameter vs standard | Approx. diameter* | Typical fit |
|---|---|---|---|
| Undersize | about 1/64″ smaller | ~0.885″ | smaller hands, many women and junior golfers |
| Standard | baseline | ~0.900″ | average adult hands (most common) |
| Midsize | about 1/16″ larger | ~0.960″ | larger hands, or players who grip too tightly |
| Oversize / jumbo | about 1/8″ larger | ~1.02″ | large hands, arthritis relief, quieter hand action |
*Diameters are measured 2 inches down from the butt cap using Golf Pride specifications and vary slightly by brand.
These increments are a guide rather than a rulebook. No industry body forces every “midsize” grip to measure the same, so sizing drifts between brands. Karma’s midsize grips run around +1/32″, closer to standard, while Golf Pride’s midsize grips sit at a fuller +1/16″, according to Value Golf. At the far end, JumboMax builds grips up to +3/8″ larger than standard, the widest on the market and the type Bryson DeChambeau plays.
Grip size vs core size
Two different measurements both get called “size,” and mixing them up is the most common source of confusion. The categories above describe the outer diameter, the thickness a golfer feels in the hands. Core size is something else entirely. It is the inner diameter of the grip, the hollow channel that slides onto the shaft.
Core size exists so the grip matches the shaft it is installed on. Most grips come with a 0.580″ or 0.600″ core to fit the butt diameters of common golf shafts, and the two get used interchangeably on standard shafts because the gap between them is small. A few grips also come in narrower or wider cores for junior or oversized shafts.
| Grip (outer) size | Core (inner) size | |
|---|---|---|
| What it measures | Outer diameter, the feel in the hands | Inner diameter, the hole for the shaft |
| Why it matters | Matches the grip to the golfer’s hand | Matches the grip to the shaft |
| Common values | Undersize, standard, midsize, jumbo | 0.580″, 0.600″ (occasionally .500″ to .620″) |
A player choosing a grip cares mostly about the outer size. Core size comes into play at installation, and a club-fitter or the shaft’s own specifications will point to the right one.
How grip size affects the swing
Because the hands are the swing’s only contact with the club, grip thickness changes how freely they can rotate through impact. A thinner grip lets the hands turn over more actively. A thicker grip quiets that rotation and asks the hands to do less.
That difference shows up in ball flight. A grip that sits too small for the hands tends to encourage overactive hands and shots that pull or hook to the left for a right-handed golfer, while a grip that runs too large can make it harder to square the face, leaking shots out to the right as a push or slice, as Worldwide Golf Shops explains. The effect is real, though grip size is one variable among many, and a stubborn miss usually traces back to swing mechanics rather than the grip.
Comfort counts as much as ball flight. A grip that fits reduces the pressure a golfer needs to hold the club, which eases strain on the fingers and wrists over a full round. This is why larger grips are a common recommendation for players managing arthritis or sore hands.
How the right grip size is determined
Grip size is chosen by matching the grip to the hand, and the starting point is a hand measurement. Fitters measure the lead hand, which is the left hand for a right-handed golfer, from the crease of the wrist to the tip of the middle finger, then read that length against a sizing chart.
| Hand length (wrist to middle fingertip) | Suggested size |
|---|---|
| Under 7″ | Undersize |
| 7″ to 8.25″ | Standard |
| 8.25″ to 9.25″ | Midsize |
| Over 9.25″ | Oversize / jumbo |
Glove size is a rough cross-check, though it reflects palm width more than finger length and is less reliable than measuring, as Worldwide Golf Shops notes. When a hand falls between two categories, golfers can fine-tune without buying a different grip. Adding layers of build-up tape under the grip raises the diameter in small steps, and club-fitters reckon about three wraps of standard tape adds roughly 1/16″, enough to move a standard grip toward midsize feel, per GolferHive.

Frequently Asked Questions
Does grip size matter?
Yes. Grip size affects how freely the hands release through impact, which influences both ball flight and comfort. A well-fitted grip also lowers the pressure needed to hold the club, which reduces strain over a round.
What is the most common golf grip size?
Standard is the most common. It ships on most stock clubs and fits the majority of adult hands, which is why fitters treat it as the default before adjusting up or down.
Is a bigger grip better?
Not by default. A larger grip quiets the hands and can help players who grip too tightly or fight a hook, but it can dull the feel for others. The right size depends on hand size and personal preference.
What grip size do most tour pros use?
Most PGA Tour players use standard grips, with some running midsize on their irons or building up a standard grip with tape. Oversized putter grips, by contrast, are now common across the tour, per Grips4Less.
Can grip size be changed without a new grip?
Yes. Adding build-up tape under an existing grip raises its diameter in small increments, which lets a golfer fine-tune the feel between standard sizes without regripping.
Should every club have the same grip size?
Most golfers keep one size across the set for a consistent feel, though the putter is usually treated on its own. Putter grips follow their own sizing conventions, and oversized options are popular for steadying the stroke.
