Jumbo Grip
A jumbo grip is a golf grip at least 1/8 inch larger in diameter than a standard grip. It is the thickest of the common grip sizes, and the terms “jumbo” and “oversize” are used to mean the same thing.
What is a jumbo grip?
Grip size in golf is a specific measurement rather than a loose label. Every size is described by how much bigger it is than a standard men’s grip, which measures 0.900 inches in diameter two inches down from the butt cap, according to Hireko Golf. A jumbo grip adds at least 1/8 inch to that, landing at roughly 1.02 inches or more.
The word “oversize” appears just as often as “jumbo” on packaging, and for most brands they point to the same thing: a grip noticeably fatter than standard. A player picks one up and feels the difference straight away, which is not true of the smaller step up to midsize.
Golfers reach for a jumbo grip for a handful of practical reasons. Some simply have large hands that a standard grip can’t fill. Others want to hold the club more softly, and a good number are managing hand or joint pain that a thicker, more cushioned surface helps ease. The grip does not change the clubhead or the shaft, only the size and feel of the one part the hands actually touch.
Jumbo grip sizes explained
Grip sizing runs on a simple scale, with each step measured against the 0.900-inch standard. Most jumbo grips sit at +1/8 inch, but the category stretches further for players who need it.
| Size | Diameter (approx.) | Difference from standard |
|---|---|---|
| Standard (men’s) | 0.900″ | baseline |
| Midsize | 0.960″ | +1/16″ |
| Jumbo / oversize | 1.02″+ | +1/8″ or more |
| Extra-large jumbo | ~1.15″ to 1.28″ | +1/4″ to +3/8″ |
One quirk trips people up: a “jumbo” from one brand can measure the same as a “midsize” from another. Hireko Golf points out that a grip labelled jumbo might be +1/16 inch in one product line and +1/8 inch in another, so the number on the spec sheet matters more than the name on the label. Brands such as JumboMax build their whole range around the larger end, offering several sizes that all count as oversize.
Why golfers use jumbo grips
The most common reason is grip pressure. Many players squeeze the club far harder than they need to, a habit coaches sometimes call the “death grip,” and that tension travels up through the forearms and shoulders. A fatter grip fills the hands more completely, so it takes less effort to hold on, which tends to relax the whole chain. Golf Pride notes that grip diameter can influence grip pressure and wrist action, though the effect varies from player to player.
Comfort is another big one. For golfers dealing with arthritis or general joint pain, a standard grip can be hard to hold for a full round. The wider surface of a jumbo grip means the hands don’t have to close as tightly, and softer models spread the shock of impact over a larger area. MyGolfSpy lists arthritis relief among the main reasons players move up in size.
Hand size matters too. Golf Pride recommends a jumbo grip for players whose hands measure between 9.1 and 10 inches from fingertip to the base of the palm, and generally suggests larger sizes for anyone in an XL or 2XL glove. When a grip is too small for the hands, the fingers can wrap too far around and dig into the palm, which lets the club move around during the swing.
There is also a shot-shape angle. A thicker grip physically slows how fast the hands and wrists can roll through impact, which can quiet a golfer who fights a hook. Golf Digest, citing club fitter Zimmerman of RedTail, reports that larger grips tend to help a player struggling with a hook, while smaller grips help the hands release to square the face for someone fighting a slice.
Jumbo vs. midsize vs. standard grips
Most confusion about jumbo grips comes from mixing them up with midsize. The gap is real: midsize is a gentle bump, while jumbo is a size a player feels the moment the club is in hand.
| Standard | Midsize | Jumbo / oversize | |
|---|---|---|---|
| Diameter | 0.900″ | ~0.960″ (+1/16″) | 1.02″+ (+1/8″ or more) |
| Best suited to | average hand size | slightly larger hands, mild tension | large hands, arthritis, heavy grip pressure |
| Feel change | baseline | subtle | immediate and obvious |
| Effect on hands | neutral | slightly quieter | noticeably quieter release |
A player unsure which way to go often starts with midsize, since it is the smaller change and easier to adjust to. Jumbo is the bigger commitment and, as Golf Pride advises, worth testing on a single club before regripping a full set. Build-up tape is another route: adding wraps under a grip during installation nudges the diameter up without switching to a different core size.
Downsides of jumbo grips
A jumbo grip is not right for everyone, and the same thickness that quiets the hands can work against certain players. The clearest trade-off is feel. Around the greens, where soft chips and long lag putts depend on feedback through the fingers, some golfers find a thick grip dulls the connection to the clubhead.
The other risk is direction. Because a jumbo grip slows the hands through impact, it can make a slice worse for a player who already needs the clubface to release and turn over. Superstroke and other fitters flag that golfers battling a slice or push, and those trying to build a draw, usually do better with a smaller grip. This is why fitting on one club first tends to beat regripping everything on a hunch.

Frequently Asked Questions
What size is a jumbo golf grip?
Most jumbo grips measure at least 1/8 inch larger than a standard 0.900-inch grip, so around 1.02 inches or more. Some brands go to +1/4 inch or +3/8 inch for the largest hands.
Is an oversize grip the same as a jumbo grip?
For most purposes, yes. The golf industry uses “oversize” and “jumbo” interchangeably to describe any grip meaningfully larger than standard, though exact diameters still vary by brand.
Do any tour players use jumbo grips?
Bryson DeChambeau is the best-known example. He plays JumboMax grips on every club as part of a swing built around quiet hands and consistent hand placement.
Do jumbo grips help with arthritis?
Many golfers with arthritis find them easier on the hands. The larger diameter reduces how tightly the fingers have to close, and softer models cushion the impact of each shot.
Can a jumbo grip cause a slice?
It can for some players. By slowing the release of the hands, a jumbo grip may leave the clubface open at impact for a golfer who already slices the ball.
