The Maltby Playability Factor is a numerical rating system that tells how forgiving a club is.
The first time I encountered the term “Maltby Playability Factor” was when I was in the process of purchasing my first golf club. A friend of mine recommended looking into it, but I found myself perplexed by its meaning. Over the years, I’ve observed many golf enthusiasts grappling with the concept of the Maltby Playability Factor. In this article, I aim to provide you with a comprehensive understanding of what the Maltby Playability Factor is, its club classification system, and the significance it holds.
In this article, I’ll delve into what MTB is, its constituent factors and components, and the advantages it offers to golfers.

What Is the Playability Factor?
The Maltby Playability Factor (MPF) is a numerical rating system that is used to evaluate and differentiate the playability of iron designs. It was introduced in 2002 by renowned club designer and engineer Ralph Maltby. The Maltby playability factor gives golfers a more objective view of how forgiving and user-friendly a golf club is.
Every golfer wants a club they can easily use and manipulate; that is what playability is all about. All irons are not the same; some are easy to hit, and some are not. So, MPF lets you know how easy it is to use a particular club.
Different characteristics of the club are considered to calculate the playability of a club. These factors greatly influence the interaction between your club and the golf ball. Some of the factors include the size, shape, weight, center of gravity, club face, etc.
Component of the Maltby playability factor
| Component | Description | Effect |
| Vertical Center of Gravity (VCOG) | This is the measure of how high or low the center of gravity is placed in a club. | Low VCOG equals more forgiveness. |
| Horizontal Center of Gravity (HCOG): | This is a measure of the distance between the position of the center of gravity and the center of the club face. | Low HCOG equals more forgiveness. |
| Moment of Inertia (MOI) | This is a measure of a clubhead’s resistance to twisting at impact. | A higher MOI means the club is more forgiving, as it helps keep the ball from going too far offline. |
| Offset | This is the distance between the hosel and the face of the club head. | The greater the offset, the more forgiving it is. |
| Face Size. | The face is the part of the clubhead that strikes the golf ball. | A large club face offers more forgiveness. |
| Hosel Length | The hosel is the part of the club that connects the shaft to the club head. | The hosel length does not have a direct effect on the MPF of a golf club. But it affects the spin rate and launching angle, which in turn affect the MPF. A longer hosel will produce a higher launch angle, which will make the club more forgiving and also produce more distance. |
Calculating and Interpreting the Maltby Playability Factor
Calculating the Maltby playability factor is not a straightforward thing because several measurements and calculations are needed to get the final MPF. The process of determining the MPF of a club can be done in four steps:
- Subtract the vertical COG from the C dimension.
N.B.: The C dimension is the horizontal distance between the CG and the hosel.
- Subtract any COG correction factor points.
- Add the playability correction factor points to the Moment of Inertia.
- Add 30 points to the Maltby playability factor for every iron.
Based on the MPF rating, clubs are classified into different categories, with each category representing a range of 150 MPF points. The higher the Maltby playability factor, the more forgiving the club is. Below is the classification of each club and what they represent.
Player Classic: 0–250 MPF
These clubs are considered blades and are the hardest type of club to use. Only a few tournament pros still play clubs in this category. The center of gravity for these clubs is usually higher and toward the heel. When using clubs in this range, you must strike the ball very close to the club’s center of gravity. They are less forgiving; however, these clubs give you maximum control. Examples of clubs in this category include the Nike Vapor Pro Combo and the Mizuno MP-18 SC Irons.
Classic 251-400 MPF
Good for players with very low handicaps (0–5). Used by some tournament pros. There are no game-improvement features for these clubs. Examples of clubs in this category include Mizuno JPX 921 Forged Irons, Srixon Z-Forged Irons, and Honma T//World 757 Forged Irons.
Conventional 401- 550 MPF
Good for players within the 0–14 handicap range. Golfers with These clubs are typically used by golfers who have a moderate swing speed and want to improve their ball striking. Anyone with a handicap above 14 will have to go for the game improvement categories. Examples of clubs in this category include the Callaway Rogue ST Max Irons, TaylorMade SIM2 Max OS Irons, and Mizuno JPX 921 Forged Irons.
Game Improvement: 551–700 MPF
These clubs are considered to be better players’ irons. They are easy to hit and give a good combination of forgiveness and feel, although they may not be as forgiving as game improvement clubs. Examples of clubs in this category include the Callaway Apex MB Irons and the TaylorMade P7MB Irons.
Super game improvement 701–850 MPF
They are designed to be forgiving on mishits and provide good distance. These clubs are typically used by golfers with moderate swing speed, achieve consistency, and want to improve their ball striking. Becoming more popular with tournament pros. Examples of clubs in this category include the Callaway Apex 21 Irons, TaylorMade P7MC Irons, and Ping i525 Irons.
Ultra Game Improvement (851 MPF and Above)
The most easy-to-use of all club designs They are the most forgiving clubs on the market, and you almost cannot tell a loss of distance. These clubs mostly have a low center of gravity and are a good fit for golfers who struggle to hit the ball consistently well. The downside is that you cannot achieve much precision and control with these clubs. Also, you may not get the type of feel and feedback you will get from other clubs. Examples of clubs in this category include the Mizuno JPX921 Hot Metal Pro Irons, the Ping G425 Max Irons, and the Titleist TSi2 Irons.
Benefits of the Maltby Playability Factor
The Maltby playability factor has helped improve golfers experiences in different ways. Here are some of the benefits:
- Helping in the classification of clubs
- The knowledge of MPF helps you make an informed decision when choosing a club.
- It boosts your confidence since you know that you are using clubs that are designed to help you hit the ball well.
- Enhances your golfing experience, as you will be less frustrated by mishits.
Conclusion
The MPF is an important factor you should check before buying any club. Although other factors such as the feel, sound, look, and swing speed are also important, Checking out the MPF will help you choose the club that has the level of forgiveness that fits your level of handicap.
