If you are following golf for a long period, then you must have noticed the dimples on the surface of a golf ball. Have you ever asked yourself about the necessity of those dimples on a golf ball? Dimples are the most important part of a golf ball. Without these dimples, the hitting style of players would not be the same.
USGA does not regulate the numbers of dimples that should be on a golf ball. But in general, there are 300-500 dimples on a golf ball.
The record of dimples on a golf ball is approximately 1077.
Curious about the science of golf balls and dimples?
Stay tuned for knowing the basics.

Why do golf balls have dimples?
The reason for all those dimples on a golf ball is pure science. A golf ball is small in size. A golf ball is around 1.68 inches and golf ball weighs around 45.93 grams (0.1012 pounds). In a golf ball, there are more than 300 dimples on the surface.
All these dimples is been implemented on the surface of the ball is to reduce the wind resistance or the aerodynamic drag.
When you can reduce the drag you will be able to let the ball go further.
When a ball is flowing in the air, the airflow interacts with the surface and can greatly affect the drag. If the ball is plain without any dimple then there will have a little pressure on the opposite side of the ball and that will create drag.drag will create disturbance for the ball to go further.
When there will have dimples on the surface of the ball, the air needs to pass through the dimples. A lot of dimples mean great turbulence or disturbance. This air turbulence or disturbance will reduce air drag and this will help the ball to move further.
When dimples are being used on the surface of the ball, the air is detached for one point, and at another point, it needs to reattach. This detachment and reattachment will create a disturbance of the air motion and this will provide enough chance for the ball to move further. More dimples mean low drag and more speed.
A ball with dimples will go almost twice as far as a plain ball. There is a principle about the air movement which is known as Bernoulli’s principles. The principle suggests that-if the speed of the airflow is increased then the pressure of the airflow in the ball is decreased. That is what creates more lift for the ball.
So it can be said that it is mandatory to have dimples on the surface of the ball. Otherwise, the players had to work more hard to take the ball into the hole. Without those dimples, they needed to be more precise and accurate.

Regulation of golf ball dimples
USGA does not regulate the numbers of dimples that should be on the surface of the ball. It is all about the quality of the ball. For ensuring the quality as much as dimples are necessary that should be provided.
The numbers of dimples that we found in any golf ball is from 300 to 500.but more than 500 dimples ball is also possible.
You should not worry if you ever found a ball with more than 500 dimples. Even the record for having most numbers of dimples in a ball is 1077. The common number of dimples possible in a ball is 336.
Dimples on a golf ball are the key feature of that ball. At the beginning of golf- players needed to be more accurate about their shot and it was tiresome putting the ball into the hole. But science has made everything easier and now by balancing with the air motion dimples have been produced on the ball and now it is quite easier to hit the ball perfectly with a perfect balance.
If you are not aware of the science behind all those dimples on a golf ball then you may wonder why there are too many dimples on a golf ball. Is it necessary or is it just for increasing the beauty of the ball?
But the knowledge that you can give you a more certainty is that it is totally science and physics which is responsible for all these dimples on the surface of the ball.
All these dimples reduce the air drag or pressure that creates more lift. These dimples produce air turbulence or air disturbance, which reduces air drag and gives the chance to stay the ball more into the air and to move further than a plain ball.
