How many dimples are on a standard golf ball?
There are more than 300 dimples on a standard golf ball, and they are therefore more than just aesthetics. Dimpled golf-ball can fly almost twice as far as they would if they were smooth. In the mid-19 th century, players noticed that old-scratched-up golf balls flew farther than newly polished spheres.
What is the importance of dimples on a golf ball?
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.
Is less dimples on a golf ball better or worse?
The number of dimples that are on a golf ball may seem random, and it may even seem inconsequential, but the truth is that the dimples on a golf ball are very intentionally designed and placed, and the number of dimples on a golf ball is carefully determined. More dimples being on a golf ball are not necessarily better.
How do dimples on a golf ball increase the distance it will travel?
Dimpled golf balls travel further than smooth golf balls is because the dimples on a golf ball create turbulence in the boundary layer. This actually helps reduce drag and increase lift. The dimples actually scoop up air and move it back towards the rear of the ball as the ball spins.
Do dimples on a golf ball make it go further?

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.
Why do dimples reduce drag?
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.
Why do golf balls have 336 dimples?
Essentially, golfers would have little hope controlling a smooth golf ball. 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.
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.
Which brand of golf ball goes the farthest?
Titleist Velocity Golf BallsWe discovered that the Titleist Velocity Golf Balls are the undisputed champs as far as distance golf balls go. Golf balls should prioritize essential factors such as spin, control, and feel.
How many dimples does a Callaway SuperSoft golf ball have?
Both the Callaway SuperSoft and Pinnacle Soft have 332 dimples. The SuperSoft's have a hexagonal dimple design. The Pinnacle soft's have an icosahedral shape. Both balls amplify your distance.
Why don't we put dimples on cars?
The dimples in a golf ball promote an earlier transition to turbulent flow and thus reduce the pressure drag of the golf ball, so it can fly further. In a car, the size is large enough to develop a turbulent boundary layer early on. Dimples would not help, but increase drag slightly.
Do dimples make a car faster?
Adam Savage and Jamie Hyneman at Mythbusters tested 3 Ford Taurus cars: one normal car, one car covered in smooth clay, and one covered in clay with 1,082 dimples scooped out. Sure enough, while the smooth cars could drive 26 miles on a gallon of gas, the dimpled car drove almost 30 miles!
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 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.
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 .
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 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.
The Story of How Golf Balls Got Their Dimples
In the mid-1800s golf balls were made of a leather cover stuffed with chicken or goose feathers and coated with paint. Known as a ‘featherie’, they were difficult to make consistently round, which made their flight irregular. They also became heavier when wet, which reduced distance. To top it all off, they were very time consuming to make.
The Combination of Lift and Aerodynamic Drag in a Golf Ball
The dimple pattern on golf balls today is there because of the two major influences the dimples have on a ball’s flight.
Why does a dimpled golf ball travel further than a smooth golf ball?
Dimpled golf balls travel further than smooth golf balls is because the dimples on a golf ball create turbulence in the boundary layer. This actually helps reduce drag and increase lift.
Do non dimpled golf balls go farther?
After watching Brian hit a series of 8-iron shots with both types of ball, our students easily concluded that a golf ball without dimples did not go nearly as far as a ball with dimples, and flew with a different trajectory.
How the dimpled design of golf ball surfaces allows greater distance to be achieved than by striking a smooth ball?
In a dimpled ball, however, the airflow changes drastically. Therefore, a much smaller wake is created behind the ball, which reduces drag, i.e. the backward pull on the ball. That’s why a dimpled ball is able to travel much faster and cover a greater distance than a smooth golf ball.
What makes a golf ball travel farther?
As a golf ball travels through the air, wind resistance creates drag, which slows the ball down. The dimples on a golf ball reduce the drag of the air making it possible for the ball to go faster and farther.
Why are there 336 dimples on a golf ball?
So, any ball with number of dimples less than 300 or more than 500 is not optimised for performance. So, most manufacturers have around 350-450 dimples on their golf balls. 336 dimples is believed to be a totally optimised number.
Why are golf ball dimples different sizes?
The dimples work to break the air around the ball in flight, and have two key characteristics that are measured: Lift and Drag. The ideal dimple design is a combination balancing the lift and drag of the ball. We vary the diameters, shapes, total coverage, edge angles to control these two key variables.
How many dimples does a Pro V1 have?
The new Pro V1 has 388 dimples, and the new Pro V1x has 348 (both in a tetrahedral pattern), marking the first time the dimple counts have changed since 2011. Dimple patterns, however, are far more than simply the number of them.
Why do golf balls have dimples?
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.
Why do dimples affect the distance the ball can go?
The reason why dimples affect the distance the ball can go is because the dimples on the surface of the ball cause the ball to spin in the air. This backspin motion creates a low-pressure zone behind and underneath the ball while in flight, effectively pushing the ball upwards, which translates to longer air-time.
How many dimples does a 1070 have?
The Dimple 1070 has 414 large dimples and 656 small dimples, making it a non-regulation golf ball. The Mizuno RB 566 is a regulation ball that has 566 micro-dimples, which are more dimples than any other regulation golf ball.
What affects the spin of a golf ball?
The spin of the ball is affected by the depth of the dimples. Shallower dimples mean more spin. The way the dimples on a golf ball are shaped and laid out is more important than the actual number of dimples on the ball.
Why are dimples important in golf?
The dimples on a golf ball are crucial. They determine all of the major aerodynamic properties of a golf ball, which ultimately determines how well the ball performs during a game. More dimples on a golf ball do not necessarily make the ball better, but rather the way the balls are laid out and how they are designed.
How does the number of dimples affect the drag of the golf ball?
This means that if you prefer a golf ball to move a little more slowly through the air to compensate for a specific swing or hit style , then the highest number of dimples you can find will be the way to go.
Why is a lower number of dimples better?
Having a lower number of dimples will result in less drag, and so the ball with move more quickly through the air, being slowed down less by the air around it. If you prefer a fastball, then choosing one with a lower number of dimples is a better option for you.
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 is the sheath of air traveling viscously with the moving ball called?
To return to the dimpled golf ball: the sheath of air traveling viscously with the moving ball is called the boundary layer.
Do golf balls cause turbulence?
Answer. Clearly, dimples on golf balls are going to create additional turbulence. And generally turbulence is a bad thing for a body moving in a resisting medium. A swimmer, for example, wants as little turbulence as possible, to give as little resistance as possible. But never say never.
