Dimples do make a golf ball fly farther. Without dimples, golf balls do not spin well and have too much drag while in flight to travel a long distance. Golf balls with dimples have been proven to travel at least 160 yards farther than smooth golf balls.
How do they put the dimples on a golf ball?
Golf manufacturers don’t put dimples on golf balls because it looks good. There is real science behind their use. A flat or irregular object moves through the air in an inconsistent, fluctuating manner because of how air flows over it. So golf balls without dimples would travel unpredictably through the air.

Why does golf ball have dimples on its surface?
How Do Golf Ball Dimples Affect Lift and Drag?
- As the air hits the dimples on a golf ball, small pockets of turbulence are created. ...
- The air flowing over the ball thus sticks closer to the ball’s surface and flows off the ball further back.
- This creates a smaller wake, which means less drag and a ball that flies farther and smoother.
How do dimples affect a golf ball?
Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball's surface. This allows the smoothly flowing air to follow the ball's surface a little farther around the back side of the ball, thereby decreasing the size of the wake.
Is it better to have more or less dimples on a golf ball?
The number of golf ball dimples is less important than the shape and depth of the dimples. The number of dimples can affect drag, so it is important to not have too many dimples. Between 330 and 400 dimples is the optimum number. More dimples mean more focussed control over the ball trajectory.
What would happen if a golf ball did not have dimples?
It's easy to assume a ball would go farther if it didn't have indentations all over the cover, but in actuality, a ball without dimples would be nearly impossible to keep in play. "Dimples are what make the golf ball fly," said Nardacci.
Do dimples increase aerodynamics?
First, dimples allow air to flow more smoothly around a ball's surface, which decreases the wake and low-pressure area behind the ball, resulting in less drag. Second, the dimples increase lift by causing the air to move faster at the top of the ball, creating lower pressure there.
How many dimples are on a Titleist Pro V1 golf ball?
388 dimpleNew Spherically-tiled Tetrahedral Dimple Designs– featuring a 388 dimple layout for Pro V1, and 348 for Pro V1x – are optimized to each model to maximize distance and flight consistency. Pro V1 maintains its penetrating trajectory while Pro V1x will fly higher than the prior generation.
Do golf ball dimples reduce drag?
Golf ball dimples reduce drag by creating a turbulent boundary layer flow around the ball. The boundary layer is defined as a thin layer of fluid dragged by the ball. By creating this turbulent boundary layer, the separation point decreases.
Why do golf balls have 336 dimples?
When dimples are added to a golf ball, it creates a tiny layer of air around the golf ball that significantly cuts down drag. This forces the air to flow over a larger portion of the ball, which results in a much smoother ball flight.
How far would a golf ball go without dimples?
If you swing like a PGA Tour player, about 160 yards. According to Frank Thomas, Golf Digest's chief technical advisor and former technical director of the USGA, a smooth golf ball with no dimples would travel about 130 yards when hit with a modern driver by a tour-caliber player.
Why is a golf hole 4.25 inches?
Four-and-a-quarter inches in diameter. R&A ADOPTS 4.25-INCH HOLE SIZE That first hole-cutting implement utilized a cutting tool that was, you guessed it, 4.25 inches in diameter. The folks running the R&A apparently liked that size and so adopted it in their rules for 1891.
Why don't we put dimples on cars?
For a car or train, which are quite fast and very large compared to a golf ball, the boundary layer is turbulent anyway so dimples have no effect.

Which golf ball has the most dimples?
As for the highest number of dimples, that would be Ultra 500 Series Golf Balls (500 dimples). Then you also have Nike and Maxfli golf balls with +400 dimples.
How many dimples are on a professional golf ball?
On American golf balls, there are usually 336 dimples, while there are 330 on a British ball. However these numbers can vary widely. Golf balls have anywhere from 300-500 dimples. Golf ball manufacturers will manipulate the number, shape, size, and even edge angles to optimize ball flight and trajectory.
How many dimples does a Callaway golf ball have?
Hence, you need to understand everything about dimples if you want a set of golf balls that suit YOUR game. Typically though, there are 300-500 dimples on any branded golf ball. For example, TaylorMade has 322 while Callaway has 332 dimples.
How many dimples are allowed on a golf ball?
Most modern golf balls have about 300–500 dimples, though there have been balls with more than 1000 dimples. The record holder was a ball with 1,070 dimples—414 larger ones (in four different sizes) and 656 pinhead-sized ones.
Which golf ball has 500 dimples?
GOLF AERODYNAMICS. The Ultra (Registered TradeMark) 500 Series golf ball (above), introduced in 1995 by Wilson Sporting Goods Company, Humboldt, Tennessee, has 500 dimples arranged in a pattern of 60 spherical triangles.
How many dimples are in a golf ball?
Most golf balls have between 300 and 500 dimples, which have an average depth of about 0.010 inch. The lift and drag forces on a golf ball are very sensitive to dimple depth: a depth change of 0.001 inch can produce a radical change to the ball's trajectory and the overall distance it can fly.
What is the effect of the spin on a golf ball?
The spinning action makes the air pressure on the bottom of the ball higher than the air pressure on the top; this imbalance creates an upward force on the ball. Ball spin contributes about one half of a golf ball's lift. The other half is provided by the dimples, which allow for optimization of the lift force.
How does the size of a golf ball affect the amount of drag on the object?
This allows the smoothly flowing air to follow the ball's surface a little farther around the back side of the ball, thereby decreasing the size of the wake .
How long does a golf ball impact last?
The impact typically lasts only 1/2000 of a second, but it establishes the ball's velocity, launch angle and spin rate.
What happens when you rotate your hand in the air stream?
As you rotate your hand in the air stream, you vary the amount and direction of the lift and drag forces acting on your hand. A moving object has a high-pressure area on its front side. Air flows smoothly over the contours of the front side and eventually separates from the object toward the back side.
Is a dimple a shape?
Dimples have traditionally been spherical in shape, but it is possible to optimize the aerodynamic performance of other shapes. The HX golf ball by Callaway, for example, uses hexagons ( see image ). Air exerts a force on any object moving through it.
How Do Golf Ball Dimples Work?
Any object moving through the air faces the force which the air exerts on it. There are two components to the force an object flying through the air undergoes:
How Do Golf Ball Dimples Improve the Game?
Now that you understand at least a bit of the aerodynamics involved with golf ball dimples, you can look at how exactly this appears in an average round of golf. For the player, golf ball dimples serve two purposes:
Have Golf Balls Always Had Dimples?
Golf has been around for a long time, and for a lot of that time, people played with smooth balls. However, at some point in the 1800s, players noticed that their dented golf balls actually performed better than the perfectly smooth ones.
Are All Golf Ball Dimples the Same?
After learning how vital dimples are to a golf ball’s success, you may be surprised to learn that golf ball dimples are not regulated. They can have different shapes, different depths and appear in varying amounts on balls.
Golf Ball Dimples Are Not Everything
There are other things that go into how smoothly and how far a golf ball flies beside the dimples.
Conclusion
Two key forces affect your golf ball’s flight: drag and lift. Golf ball dimples have a massive impact on both, which is why they are so crucial for effective golf balls. Dimples reduce drag and increase lift.

What Happens If You Take The Dimples Away?
While they might look like simple pieces of equipment to the untrained eye, golf balls are manufactured in such a way that they are perfect for their use.
Conclusion
Golf balls need to have dimples in order to improve their flight, so they do not slice or hook.
From Observation to Mathematical Model
As a child, I occasionally would walk around a nearby golf course with my family on rainy days; the only times when no golfers would dare to play. Our own game was to find lost balls from previous, unfortunate players. The person who found the most balls would win.
The Drag Crisis Observation
Throughout history, the flows around many different shapes have been studied by scientists. For example, vortex streets are generated by the flow around cylinders. Although a sphere does not generate this type of large alternating flow structure, the flow characteristics can also be linked to the Reynolds number.
The Reason for the Drag Crisis
First of all, let’s recall that the drag of an object is caused by two sources:
Modeling the Aerodynamic Forces of Golf Balls
Now we understand why golf balls have dimples in the first place. Let’s remember that the drag is lower and therefore the ball can go further. To find out how much further the ball can go, we first need to compute its trajectory.
Finding the Optimal Launch Angle
The effect of the dimples on a golf ball should now be clear: They make the ball go further. However, in practical terms, this does not say much about how I should hit the ball.
Conclusion
In today’s blog post, we answered a seemingly simple question about golf ball dimples, which has to do with the behavior of the turbulent boundary layer over a sphere at a specific range of Reynolds numbers. This also outlines a classical process in engineering.

Difference Of A Smooth Ball And A Dimpled Ball
Dimples ensure two things about the ball. Its lift and the distance it travels. As a result, when a ball is hit, it is exposed in the open air. Allowing the air to have complete turbulence and force on the ball. So that the ball can travel smoothly for longer distances, alter the depth of a dimple, and you can see the difference.
FAQs Regarding Dimples And Golf Balls
There is no specific standard regarding the number of dimples on a golf ball. But still, the answer to how many dimples on a golf ball will be, An average golf ball has 300 to 500 dimples.
Conclusion
A golf ball has dimples not to make it look cute. But for the sake of its better performance. So when this difference was seen between a smooth and dimpled ball, it was made sure to change the ball’s structure entirely.
