Do You Know How Many Dimples On A Golf Ball Are Perfect?

When it comes to the golf ball, there are many questions that need to be answered. As passionate and professional golfers, we must know every little feature and function of every little part of the golfing equipment.

Because, in the game of golf, the smaller the feature, the more difference it makes in creating a positive impact on the golf course. And this also applies to golf ball dimples.

Why are there dimples on a golf ball? How many dimples on a golf ball? Why can’t you play with a golf ball without dimples? There are many questions regarding the golf ball dimples and the golf ball dimples purpose. And that is why I am here, right? To answer all your questions. So let’s begin.

What’s Inside: A Golf Ball – WIRED

Why are there dimples on a golf ball?

Before I give you a detailed explanation, let me answer this question in simple words. Golf balls are designed with dimples to create a lift that helps in keeping the ball in the air. They also help in reducing the drag by adjusting the golf ball’s wake.

Golf balls without dimples don’t have the capability to reduce the drag in the air as much as golf balls with dimples. And as far as the lift of the golf ball is concerned, the smooth ones cannot increase the lift as much the ones with dimples.

So when you combine the decrease in drag with the increase in lift, the golf ball tends to travel at least 3 times farther than any other golf ball without dimples. Pretty neat, isn’t it?

But how does this happen? I can explain. Dimples on a golf ball are created to produce turbulence around the ball while it is in the air. This is known as the boundary layer. What the dimples do is scoop the layer of air and set it towards the end of the golf ball.

Science of Golf: Why Golf Balls Have Dimples?

Once the direction of the air has been changed, it inevitably maximizes the total air pressure found on the backside of the golf ball.

And this, in turn, lowers the drag simply by lowering the pressure that pulls the ball back from behind. So what you finally get is at least a 50% reduction in drag. (How do dimples affect ball flight).

And what about the lift? I can explain that too. Dimples on a golf ball create lift only when there is maximum backspin. Backspin on a golf ball causes the layer of air on top of the ball to move backward faster.

And this happens only when there are dimples on the golf ball. As a result of the air on top of the ball moving backward faster, the air pressure on top of the ball is lower than the air pressure below the ball. And this is exactly what creates the lift.

Now we can move on to the next question with the dimples on a golf ball.

How many dimples on a golf ball?

When it comes to dimples on a golf ball, golf equipment manufacturing companies have experimented with all kinds of numbers. The more the number of dimples on a golf ball, the smaller they should be to be able to fit on the surface of the ball.

So it’s only logical, to sum up, that once the dimples on the golf ball get smaller, the ball becomes more and more smooth.

And we all know that it is extremely important to pick a golf ball that doesn’t have a very smooth surface, right? So how many dimples on a golf ball ensure that it is not too smooth? A golf ball with 500 dimples becomes too smooth.

On the other hand, 300 dimples are considered to be too less. So how many dimples on a golf ball are not too less or too many? A golf ball with anything between 350 and 450 dimples is regarded as the best golf ball for distance. (Scientists express their opinion about golf ball dimples)

You will find that most of the best golf balls on the market have not more 450 dimples and not less than 350 dimples. The depth, number, and pattern of these dimples might vary due to the different styles and methods of construction adopted by different manufacturers.

Why can’t you play with a golf ball without dimples?

I have already explained the ultimate golf ball dimples purpose above. Dimples in golf ball create lift that helps in keeping the ball in the air. They also help in lowering the drag by adjusting the golf ball’s wake. And when these two things happen, the distance of the golf ball increases by at least 50 percent.

So what happens when you play with a golf ball without dimples? The distance traveled by the golf ball gets cut by half. So do golf balls really matter when it comes to distance? The answer is an astounding yes, isn’t it?

You also need to know that the balls used in other sports like football and tennis are not built with dimples. But they still seem to work just fine. And why do you think that is?

As far as a football is concerned, it already has a pretty streamlined structure. The ball’s wake is already small and that is why it doesn’t need any dimples to reduce the drag.

And as for tennis balls, their surface is rough enough due to the balls’ fuzz and construction seams. And this roughness has the tendency to affect the wake behind the tennis ball.

Conclusion

So I hope now you know the correct answer to how many dimples on a golf ball are not too less or too many? There is no one right number. It can be anything between 350 and 450 dimples.

You should know that there aren’t any restrictions imposed on the number of dimples on a golf ball. But there are certain rules related to aerodynamics. Aerodynamics is the overall symmetry and distance that highly depends on the golf ball’s orientation.

I would like to end the article by once again stating the fact that most of the best golf balls on the market have not more than 450 dimples and not less than 350 dimples.

The reason why there isn’t any one definitive answer is because there are other factors, apart from dimples, that affect the flight of the golf ball. These factors are the surface roughness, depth, dimple edge shape, and profile shape of the golf ball.

And different manufacturing companies make use of different methods and shapes for constructing golf balls. Hence, the variation in the number of dimples built on the golf balls.
