As the air hits the dimples on a golf ball, small pockets of turbulence are created. This creates a small layer of air close to the surface of the ball. The air flowing over the ball thus sticks closer to the ball’s surface and flows off the ball further back.

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.
What if golf balls didn't 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.
Why are there 336 dimples on a golf ball?
“A golf ball has dimples to reduce wind resistance or aerodynamic drag, Quintavalla said in a USGA profile on golf ball dimples. “When you reduce it, you can make golf balls go a lot farther.”
Do golf ball dimples affect putting?
With no significant associations identified with human participants, dimple error is unlikely to have any implications on putting performance. This is also apparent with side spin where only 20% of variance was accountable for one putter-ball combination.
Do dimples on a golf ball increase 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.
How many dimples does a Titleist Pro V1 have?
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.

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.
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.
Are golf balls perfectly balanced?
You might not know this, but all golf balls are not balanced properly on the inside. Many balls have a COG that is imperfect, and ANY imperfection of the COG can cause your ball to go off line. These imperfections can cause not only your putts to go off line but your drives as well.
How many dimples does a Callaway golf ball have?
Typically though, there are 300-500 dimples on any branded golf ball. For example, TaylorMade has 322 while Callaway has 332 dimples. Then there's Titleist Pro V1, one of the best beginner golf balls, with 352 dimples.
What is the depth of a golf ball dimple?
roughly 0.010 inchThe size of golf ball dimples are most frequently measured by their depth. The average depth of a golf ball dimple is roughly 0.010 inch.
Which golf balls have the most dimples?
On the new Vice Pro Plus, you will see 336 dimples, while on Tiger Woods' Bridgestone Tour B XS ball there are 330 dimples. The Titleist Pro V1 ball consists of 352 dimples. You can therefore see that most of the biggest balls in golf today feature around the 320 to 350 dimple mark.
How many dimples are in a golf ball?
Most balls on the market today have thus converged to the middle ground with between 350 and 450 dimples (although one company produced a ball with 812, which didn’t set the world on fire). So next time there’s a wait on the tee, check out the dimples (the ones on the golf ball.)
How far does a golf ball travel with no dimples?
The fact is that a perfectly smooth golf ball with no dimples would travel about 130 yards when hit with a driver by a good player. On the other hand, a ball with well-designed dimples, struck the same way, will travel about 290 yards. Why the difference?
Why do smooth balls have more drag than nonspinning balls?
The ball must, however, spin for the lift force to be created , and unfortunately a spinning ball has more drag than a nonspinning ball. But this is the trade off.
What happens to the dimples as the number of dimples increases?
Eventually, as the number increases, the dimples get smaller and the ball becomes almost smooth--and will perform likewise. So a compromise is the answer.
What determines the distance a ball will go?
It is the combination of the lift and drag properties of the ball, as well as its speed, launch angle and spin rate, which will dictate the flight path or trajectory of the ball, and thus the distance it will go.
Do golf balls have dimples?
Yes there are. The size, shape, depth, number, distribution pattern and overall surface coverage of the dimples all influence the ball’s aerodynamic lift and drag properties. Unfortunately, analysis of air flow over a golf ball’s dimples is not a huge priority for NASA, and dimples are not a threat to national security, ...
What are dimples on golf balls?
The dimples that are made on the surface of a golf ball during manufacture are purposefully designed to affect the ball in flight, including how far or how short the ball will travel after being hit.
How Do Dimple Patterns Affect A Golf Ball?
The number of dimples that are on a golf ball is a factor, but what about the pattern of the dimples and how they are shaped? How do dimples patterns affect a golf ball?
Do Dimples Make A Golf Ball Fly Farther?
Dimples that are on a golf ball are specifically and intentionally designed to alter the aerodynamic properties of the ball while in the air. Part of this is the distance that the ball travels.
What Is The Optimal Number Of Dimples On A Golf Ball?
There is such a wide range of dimples used for golf balls. Some have many, and others have few, but what is the optimal number of dimples on a golf ball?
How do dimples affect golf ball spin?
The number of dimples on a ball affects the drag of the ball, not necessarily the spin. 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.
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 does a golf ball spin less?
If the golf ball has deep dimples, it spins less while in the air than if it were to have shallow dimples. This also means that the size of the dimples is important for how the ball spins.
