What is MOI in a golf club?
Generally known as MOI in the golf world, moment of inertia is basically the measure of a clubhead's resistance to twisting when a ball is struck away from the sweet spot. This means the higher the clubhead's MOI, the less it will twist and the straighter the ball will fly on a mishit.
Why are golf drivers Hollow?
The first, and most important, was the weight savings that were achieved. Swinging a hollow metal-headed driver meant the overall weight of the club could be lower, which would instantly increase swing speed. At the same time, the heads could be made bigger thanks to the weight savings.

What irons do PGA pros use?
Many PGA Tour pros and better players use blade irons or sleek cavity-back designs that are made for workability. Essentially, to work the ball left or right, skilled players hit controlled mishits to manipulate spin and launch. High MOI simply hinders that ability.
Why do golfers use irons?
That’s because less twisting of the face actually reduces the ability to hit draws and fades on purpose.
Is high MOI good for golf?
For most golfers, high MOI is a good thing. Typically, when a golf ball is hit on the toe of a club, the face gets twisted open; when it hits the heel, the face gets twisted closed. The result is a golf ball that flies offline and with less speed.

How to find the right MOI for a golf club?
The “favorite club†is measured for its MOI using the TWGT MOI Matching System, after which the other clubs are then built to match the MOI of that “favorite club (s)â€.
What is MOI in golf?
The MOI of any object is a measurement of its resistance to being put in motion around a defined axis of rotation. Related to golf clubs, if each club in a set requires a different amount of force to swing the club (swinging the club to rotate around our body), the golfer cannot be as consistent swinging each different club in the set. In most simple form, MOI matching scientifically makes each club require the same amount of effort to swing. This is what makes MOI matched clubs offer better shotmaking consistency than swingweight matched clubs. Swingweight matching does not make each club the same in terms of the amount of force required by the golfer to swing each club and hit the shot. MOI matching does. However, because golfers can be quite different in their strength, tempo and swing mechanics, the right MOI must be identified and custom fit for each golfer to allow the concept to properly work.
How much does the swingweight increase with a MOI matched club?
Most typical is to see the swingweight increase by 0.5 swingweight points per club down through the set. This is very definitely one of the main reasons golfers like the swing feel of their MOI Matched clubs and do experience an improvement in shot consistency.
Why did swingweight match fail?
They failed because the principle of the swingweight scale they developed could not truly accomplish the task of measuring the MOI of a golf club. Over the decades since the development of swingweight, engineers familiar with the principles of MOI have been in agreement that MOI matching would truly make all clubs within a set swing with exactly the same feel, while swingweight matching could not.
What is MOI match?
In 2006, TWGT introduced an upgrade to the original MOI Matching system with the MOI Speed Match System. This system consists of an electronic device that directly measures the MOI of any golf club in one operation. The older MOI Matching system required clubmakers to manually measure 4 different specifications of each club and then use the accompanying software to calculate the MOI of each club. Thus, the MOI Speed Match hardware is much faster to use to quickly measure the MOI of any club.
What is a favorite club?
A “favorite club†may be defined as a club with which the golfer is most consistent over all others, and which the golfer has the utmost confidence in their ability to hit the ball solid and on-center more often than the other clubs in the set. After research and testing, TWGT believes that a one reason golfers have “favorite clubs†is that the MOI of those clubs happens to match the strength, tempo and swing mechanics of the golfer noticeably better than the MOI of other clubs.
Can you match all woods to one MOI?
No. TWGT testing and feedback from many of the clubmakers using MOI matching in their work has proven that because woods and irons are so different in their length ranges, better results are obtained by matching all the woods to one MOI, and then matching all of the irons to another MOI, with both chosen specifically for each golfer either on the basis of the “favorite club†or the “test club†approach. The difference in MOI measurement between the woods and irons typically is for the woods to be 50 g/cm2 higher in MOI than the irons.
What Is Moment of Inertia?
Why Is It Important For The Performance of Golf Clubs?
- MOI is important in golf club design because most golfers do not hit the ball in the centre of the clubface all the time. On off-centre hits the club head is forced to rotate away from the target resulting in a loss of directional control and ball speed. A high MOI means that the club is more stable and therefore more resistant to twisting, which translates to more ball speed and a straig…
