The Importance of Ball Fitting

Are the balls used by the pros,
‘fit’ for you?

Any golfer who enjoys golf wants to be accurate and to hit the ball far away. That’s why they practice every day and choose golf clubs carefully. However, golf balls are often purchased without careful consideration. This is because most amateur golfers prefer branded products used by famous domestic and international pros when choosing a golf ball. But are balls used by the pros really suitable for you?

The answer is ‘No’!

The balls that professional golfers use are golf balls that is tailored to professional abilities. They are clearly good golf balls but when used by amateur golfers who have a lot of differences in skills compared to the professionals, it does not necessarily mean a good choice. Rather, you can improve your performance by using a ball that is right for you. When choosing a club, regular amateur golfers do not use clubs with specifications used by professional golfers. The reason for this is that the swing conditions (head speed, used club, accuracy, spin amount, etc.) are very different when compared with the pros. As golf balls also have a variety of specifications, it is important to know exactly what your swing conditions are and to use the right golf ball.

Understanding Golf Ball Specifications


COMPRESSION (Compressive Strength)
  • The compression strength of the golf ball is similar to the shaft of a golf club. The golf ball is also classified according to the compressive strength, and it is preferable to select the strength depending on the swing speed.
  • Compressive strength values range from 0 to 200, usually between 50 and 120 for golf balls.
  • compression(Compressive Strength)
    Head Speed(mph) Golf Ball Compression
    High Head Speed (95mphOver) 100Over
    Mid Head Speed (80~95mphOver) 85-100
    Low Head Speed (80mphUnder) 85Under
  • Compression strength greatly affects distance according to the head speed. Since the impact amount applied to the ball differs according to the head speed, when a golfer having a low head speed hits a ball having a high compressive strength, force transmission to the center of the golf ball is not properly performed.
  • On the other hand, when a golfer with a high head speed hits a golf ball of a low compressive strength, the force applied at the time of hitting is dispersed more than necessary through the center of the golf ball, so that the accuracy of distance and direction may be lowered.


  • Shore-D marked on the golf ball refers to the hardness of the dimple cover layer. The hardness of a golf ball is usually manufactured at about 40~70. Hardness is a factor that greatly affects the hitting feel, spin and distance. The higher the hardness, the higher the repulsive force, which makes it an excellent golf ball for distance golfers but makes it a ball for control. For soft balls with low hardness, the control performance is better than distance. Because distance and spin are inversely proportional, it is also important to understand your play style and use a ball of the appropriate hardness.
  • HARDNESS (Hardness)
    Hardness (Shore-D) Spin Rate
    50 D Under High
    50 D ~ 60 D Mid
    60 D Over Low


  • The continuous design of large and small furrows on the surface of a golf ball is usually referred to as 'dimples', and this structure affects the flight of the ball depending on its size (depth) and number. The dimple of a golf ball is like a wing of an airplane. The principle of lift is also applied to a golf ball. When the ball is flying, the pressure of the air flowing on the upper surface of the ball becomes smaller than the pressure flowing on the lower surface, so that the golf ball has a floating force and remains in the air for a long time. The smaller the number of dimples, the higher the generation of lift and the higher the ball flight and the greater the number of dimples, the lower the generation of lift and the lower the flight of the ball.
    Trajectory Number of Dimples
    High 200 ~300Early Stage
    Mid 300Middle Stage ~ 400
    Low 400 Over

The secret of The Distance

Optimized ball flight is required for an outstanding distance.

For an outstanding distance, you should choose a ball with compression strength that is appropriate for your swing speed. Also, a ball flight with a moderate height trajectory is ideal. It is usually considered to be the most desirable flight to fly at a height of about 25 to 30 meters and for the flight time to take from between 5 seconds and a half to beginning of 6 seconds.

If you want to get the maximum distance from your swing, you first need to figure out your swing speed. If a golfer with a slow swing speed uses a ball of high compressive strength, the force being transmitted to the ball will be weak, making it difficult for the ball to stabilize, bringing loss to distance. Conversely, if a golfer with a high swing speed uses a ball with low compressive strength, the force being transmitted to the ball is scattered past the center of the golf ball, resulting in a distance loss. Therefore, it is important to select a ball that matches your head speed to maximize ball’s repulsive strength.

Ball flight time is also an important factor. To ensure a stable flight, you need to look at how ball dimples are designed. If your ball flight is too low, select high-trajectory dimple and if the ball flight is too high, select a low-trajectory dimple to form a stable flight trajectory that will contribute towards distance. Ball flight time is related to trajectory. If the ball's trajectory is formed at a level that is too low, the flight time will be shortened and the distance will be reduced. If the ball is flying higher than necessary, the direction of the force will be directed upward rather than forward, resulting in loss of distance.


The most important thing in golf (score, play) is accuracy. Accuracy can be roughly divided into fairway accuracy and green accuracy.

First, for fairway accuracy, it is important to know how exactly the golf ball has landed on the fairway. Beginner golfers usually try to hit the ball straight, but misses occur as they fail to get the exact impact. In such cases, choosing a golf ball that has a low spin helps in the game. This is because it minimizes the angle of deflection by generating fewer side spins during impact, thereby increasing the straightness of the ball relatively. Of course, a ball with a low spinning power is good in distance and straightness, but multiple runs may occur in the case of targeting the green.

Second, the green accuracy is related to accurate targeting towards the pin.
For intermediate and advanced golfers, if you can achieve a certain degree of swing and impact, you must target the green with precise control. Therefore, it is advantageous to select a golf ball that generates high spin and to minimize the occurrence of runs when targeting the green. However, in the case of a ball having a good spin force, the cover may have a reduced elasticity, which may result in a drop in distance compared to a ball having a low spin.

Therefore, it is necessary to find a suitable ball according to the individual’s skills and preference, as every golfer has different handicap and skills of swing speed, style, distance and spin and also their subjective preference for hitting feel, hitting sound and colors are different. Volvik Ball Fitting analyzes the ball flight through a test that takes place after the first-round consultation and recommends the most suitable ball for each golfer according to the objective analysis of the golfer’s swing and subjective preference. Selecting a ball of the right specification according to the player’s ability and preference allows the player can achieve a more stable and constant ball flight trajectory, and as a result, it will improve the distance and accuracy of the player’s performance.
