What is the MOI of a clubhead?
MOI of the clubhead around the shaft: The second example refers to the MOI of the clubhead about the shaft axis. Little is spoken about this MOI in equipment marketing, but it is an important head design factor that can affect the accuracy of the shot, not the distance. The bigger the head or the more weight that is placed far out on the toe of the clubhead, the higher the MOI of the head will be about the shaft's axis. The smaller the head or the more weight that is positioned in the heel area of the head, the lower the MOI of the head will be about the shaft's axis. The higher the clubhead MOI around the shaft, the more tendency there is for a golfer to leave the face open at impact. The lower the clubhead MOI around the shaft, the more tendency there is for a golfer to rotate the face more closed at impact.
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.
What is swingweight matching?
The current method for matching clubs in swing feel is called swingweight matching. 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. MOI matching of clubs is a swing matching system currently offered only by more advanced custom clubmakers.
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.

Why is MOI important in golf?
The real question any golfer should ever be asking is why is MOI important in golf?

What does MOI mean on a putter?
1. More MOI means more forgiveness on off-center hits. Jonathan 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.
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.
