What is moi on a golf ball?
The acronym "MOI" stands for "moment of inertia," and in golf MOI is a measurement of a club's resistance to twisting. The term is usually applied to clubheads, but can also be applied to golf balls and even shafts.
What is Momoi in golf clubs?
MOI is an acronym that stands for “moment of inertia.” This measurement (grams per centimeter squared) shows how much resistance a clubhead has to twisting.
What is moment of inertia (Moi) in golf clubs?
For golf clubs, it's typically vertical and horizontal MOI, determining how much the club twists left and right, as well up and down. In layman's terms, moment of inertia is a measure of how forgiving a golf club is. The higher the MOI, the more stable the golf club at impact.
What is a high moi Golf Club?
A high MOI golf club, however, resists that twist and reduces the effect of a mishit. In driver design, most club manufacturers try to get CG low and rearward. By placing weight far away from the face, the design will reduce twisting at impact. The result is a more forgiving club head that produces more spin and higher launch.
What does high MOI mean in golf?
MOI is an acronym that stands for “moment of inertia.” This measurement (grams per centimeter squared) shows how much resistance a clubhead has to twisting. The higher the MOI reading, the more resistance it has and the more forgiving the club will play.
How is Moi measured in golf?
The bigger MOI causes the more torque it will take to produce a certain amount of rotational acceleration. Moment of Inertia is defined by the mass and the axis the mass is rotating around. Quantitatively, the moment of inertia of each grain of mass is its mass times the square of the distance to the axis.
What is Moi and CG in golf?
Moment of Inertia (MOI) and Center of Gravity (CG) In golf, "forgiveness" refers to the engineering and/or the design elements in golf clubs that lessen the effects of bad swings and poor contact with the ball.
How do I increase driver Moi?
Adding weight, or locating weight more to the perimeter and/or rearward can raise the MOI, but by an amount that most players may or may not be able to notice.
Why is Moi important in golf?
An acronym, MOI stands for “moment of inertia.” MOI is measured in grams per centimeter squared and shows how much resistance a clubhead has to twisting. The more resistance it has, the higher the MOI reading and, importantly for golfers, the more forgiving the club will play.
What loft should my driver be?
The ideal driver loft depends on your swing speed and the attack angle. Average players that swing the club less than 95 MPH will likely find that a 10.5-degree driver performs the best. Better players who can control their drives and want the most distance will lean more towards a 9-degree driver.
What does MOI putter mean?
Moment of InertiaJonathan Wall, Managing Equipment Editor: Simply put, MOI, also known as “Moment of Inertia,” is a way to measure a putter head's resistance to twisting on putts that don't catch the center of the face. The higher the number, the more stable the putter will be.

How much does a single golf club weigh?
Individual golf clubs weigh less than 1 pound. According to golf digest, the average weight of a professional golf club is 0.73 pounds (0.33 kilos). A set of 14 clubs gives us a total dry weight of 10.22 lbs (4.64 kilos).
What does MOI mean in golf?
The acronym "MOI" stands for "moment of inertia," and in golf MOI is a measurement of a club's resistance to twisting.
What is the MOI of a golf club?
MOI of the whole club around the golfer: As stated earlier, the whole golf club also has an MOI. The longer the club, the heavier the head, the heavier the total weight of the head, shaft and grip added together, the higher the MOI will be for the whole club.
Why is a higher MOI clubhead more resistant to twisting?
But if the moment of inertia can be increased, the club becomes more resistant to twisting. Therefore, a higher-MOI clubhead will twist less on off-center strikes than a lower-MOI one, meaning less loss of distance.
How to determine MOI?
Remember, MOI has to first be defined by identifying what axis the object is rotating around. There is an MOI for the whole golf club which, when swung, is "rotated" around the golfer during the swing. There are also three different MOIs that can be measured for the clubhead itself.
Why is MOI important in golf?
The MOI of the club is important to matching the swing feel of all the clubs in the bag. Clubfitting theory states that if all clubs in a set are made to have the same, identical MOI, the golfer will be more consistent because each club will require the same effort to swing.
What is swingweight in golf?
Swingweight is an expression of the ratio of the weight in the grip end of the club to the weight in the rest of the club on down to the clubhead. Swingweight-matched golf clubs are not matched for MOI, but come relatively close to MOI matching.
What does higher MOI mean?
Higher MOI equals more resistance to the object being rotated around an axis; lower MOI equals less resistance to the object rotating around an axis. Or, in plainer English: Higher MOI equals more forgiveness on off-center strikes with your golf club; lower MOI equals less forgiveness on off-center strikes.
Why do golfers have high MOI?
This is because they want to retain the ability to work the ball left and right. A higher handicap golfer will be more likely to be trying to hit the ball straight and is more likely to miss the centre of the club face – so they will benefit from high MOI in an iron.
What does high MOI mean?
They are effectively the same thing. High MOI means high forgiveness and stability. Many club designers have told me that it’s mainly about protection of ball speed on off-centre hits. Again, we can see why this is a good thing on drivers and putters.
Why do putts go short?
It is also not going to set off straight. So when golfers leave putts short it can often be because they haven’t struck it out of the middle of the face.
High and Low MOI – What Is Better for You?
When one thing works for someone doesn’t mean everyone’s going to benefit from it. High MOI may be one of the prerequisites for the golf club to be highly forgiving but then NOT ALL players want their clubs to be that forgiving.
MOI In Putter

How Do Manufacturers of Golf Clubs Boost MOI?
The most common and effective approach to increase MOI – placing weight around the perimeter (edges) of the clubhead. With super game improvement irons, this is exactly what makes them magnanimously forgiving.
Should MOI Affect How You Choose Your Golf Clubs? (if yes, then how much?)
Ask yourself one very simple question at this point… what’s your biggest concern with your game currently? Is it not being able to hit accurate, consistent shots? In that case, high MOI plays a crucial role when it comes to what golf clubs to purchase.
Commonly Asked Questions – Moment of Inertia (MOI)
CG or COG means Center of Gravity. MOI means Moment of Inertia. The former controls launch and spin conditions. When CG is placed farther back and lower, it increases MOI and leads to a higher launch. In simpler words, more forgiveness on off-center shots.

Is a putter's MOI plastered on the head?
A putter’s MOI isn’t plastered on the head when you buy one, but you can generally assume a mallet is going to be more resistant to twisting due to its size and overall weight. Mallets are a strong option for beginner golfers because you can still miss the middle and not have to worry about the ball going too far offline.
Does a putter with more MOI fix your stroke?
A putter with more MOI won’t magically fix your stroke for you. You still need to practice your technique. If your stroke improves, your score probably will too — and on those putts that you do happen to hit off center, that’s when MOI is there to help. 1.
