What is Smash Factor in Golf?

Smash factor is a term widely used in golf to measure the efficiency of a golfer’s swing. It is calculated by dividing the ball speed by the clubhead speed. 

A higher smash factor indicates that a golfer transferred more energy to the ball, resulting in higher speed and distance.

Smash factor is an important metric, but don’t get too obsessed with this number (more on that later).

In this article, we’ll walk you through everything you need to know about smash factor. We’ll discuss how it affects your game and give you a few tips for improving this semi-important number.

Smash Factor Defined

Why Does Smash Factor Matter?

If you’re a person who values efficiency, smash factor is your kind of metric.

Here’s why smash factor matters:

The smash factor indicates how well you hit a golf ball, and it does this by measuring how you use the golf club’s potential energy. 

In other words, a golfer with a higher smash factor will be able to hit the ball farther with the same amount of effort than a golfer with a lower smash factor. 

Why, you ask?

A higher smash factor means that more energy is being transferred from the clubhead to the golf ball at impact, resulting in a faster ball speed and greater distance.

Even though a high smash factor may result in better drives on the golf course, it’s not the only factor that determines distance.

As a golfer, you should pay close attention to:

  • Launch angle
  • Spin rate
  • Ball speed

These details play a significant role in total distance.

Marty Jefferson, the Vice President of Fitting & Performance at PING, had this to say about smash factor and club fitting:

Tell your fitter that you don’t want to look at Smash Factor. Remember, ball speed is king.  For drivers, focus on increasing ball speed, optimizing launch conditions (launch efficiency) – then try to minimize your shot bend and dispersion within reason for your swing.  For irons, look at the peak height, landing angle, carry distance and dispersion, while being mindful of turf interaction and gapping.

I highlight this quote to make two points:

  1. Smash factor ISN’T the most important factor to pay attention to, especially when choosing a new club.
  2. That being said, it’s fun to optimize your smash factor and compete with the top golfers. 

As I mentioned earlier, don’t obsess over your smash factor, but also give this metric the respect it deserves.

So what is a good smash factor number?

A good smash factor number will vary by club. For example, a good smash factor for a driver would be 1.49 or higher, whereas a good smash factor for a PW would be lower (around 1.25).

The higher the loft of a club, the lower the smash factor number should be.

Trackman Golf has a blog post with some older data that’s worth considering.

Smash Factor Data (from TrackmanGolf.com)

PGA Tour Smash Factors

  • Driver – 1.49
  • 6 iron – 1.38

LPGA Tour Smash Factors

  • Driver – 1.49
  • 6 iron – 1.39

Amateur Smash Factors (with a Driver)

  • Scratch – 1.49
  • 5 handicap – 1.45
  • 10 handicap – 1.45
  • Average Golfer (14.5 handicap) – 1.44
  • Bogey Golfer – 1.43

A professional golfer may be able to achieve a smash factor of 1.52 with their driver shot, but remember, they’ve been working on their golf swing for a long time.

Factors Affecting Smash Factor

To maximize your swing efficiency and achieve an ideal smash factor, you should know the issues that can influence your smash factor. 

Attack Angle

The way your club face contacts the ball (attack angle) can make a huge difference in distance.

Whether you’re a newbie or a seasoned golfer, you probably understand that you should hit the ball on the upswing. This determines your launch angle.

A positive attack angle with a driver can help increase the launch angle and reduce the spin rate, resulting in longer drives. A negative attack angle with an iron can help increase the spin rate and control the trajectory of the ball, resulting in more accuracy and stopping power on the green.

If your attack angle isn’t good, you can try to improve this by:

  • Positioning the ball in a different part of your stance
  • Adjusting the angle of your spine
  • Modifying the length of your backswing

Centeredness of Contact

I know it sounds technical, but centeredness of contact is a “law” that focuses on where the club face contacts the ball. Similar to baseball and tennis, finding the sweet spot is crucial in golf to maximize ball speed and direction.

If you don’t hit the center of the clubface, the energy transfer will be less-than-ideal, and the ball won’t go as far. 

If you’ve been golfing for any period of time, you know the difference between hitting the sweet spot of your clubface and mishitting that club. You can feel it in the actual hit.

Launch monitors can show where you’re hitting the ball with the club face. There are also paper decals that accomplish the same thing.

Knowing where you hit the ball can help you adjust your stance, posture, swing path, or attack angle so you can hit center strikes more often. 

Solid, centered contact will likely increase your smash factor.

Club Head Speed

Since the smash factor is the ball speed divided by the clubhead speed, it’s make sense that improving your club speed is one way to improve your smash factor. 

You don’t need a college degree to know that a 100 mph swing will create more ball speed than a 70 mph swing.

With that in mind, you don’t need to swing like Bryson DeChambeau to improve your smash factor, but improving your clubhead speed will make a difference.

How Do I Improve My Smash Factor? 3 Ways

If you’re an average golfer looking to improve you smash factor, there are a number of practical areas where you can improve. When you make better contact, hit the sweet spot of the club, and elevate your swing speed, your smash factor number will follow.

Let’s briefly discuss each of these areas.

1. Hit the Sweet Spot

The sweet spot on a driver’s face is usually a bit above the center and closer to the toe. That’s the ideal spot to convert your club speed into ball speed, and ultimately get a higher smash factor.

Depending on your skill level, you might need to slow down your swing a bit to hit the perfect spot more often. It seems counterintuitive, but you want to make sure you hit the sweet spot first BEFORE you start to focus on swing speed.

Some clubs have a larger sweet spot, so if you have trouble with precision, you may want to look into a more forgiving driver.

2. Make Adjustments to Increase your Swing Speed

Boosting your swing speed will definitely improve your smash factor, but this is easier said than done.

If you just try to swing faster, your hits may be less accurate.

And as I just mentioned, hitting the sweet spot is really important.

Here are some tips to increase your swing speed without sacrificing your accuracy:

  • Avoid using clubs that are too heavy for your game. Get a club fitting.
  • Work on your flexibility to create longer backswings, which can maximize your speed potential.
  • Try different grip adjustments to see if they make a difference.
  • Opt for modern speed-maximizing clubs, as they have improved head airflow and minimal resistance.
  • Widen your stance to maintain stability, achieve a wider arc and boost your angular velocity.
  • Hit the gym and focus on workouts that target the muscles you use while swinging (pecs, glutes, lats, and forearms).

3. Make Clean Contact with the Ball

Hitting the ball cleanly can improve your smash factor. One common mistake among golfers is that they hit the ground before hitting the ball. This slows down the club head and wastes all the energy and speed created before touching the ball.

There could be many reasons why you hit the ground before the ball, but you want to make sure that nothing slows down your swing before you hit the ball.

Smash Factor FAQs

What is a good smash factor for irons?

For a 6-iron, a good smash factor would be between 1.38 and 1.39. This range is similar to scratch golfers as well as LPGA and PGA Tour players.

Can smash factor be too high? 

Not really. In fact, the smash number limits may increase as golf club and golf ball technology continue to improve. 

What is the best smash factor in golf?

The best smash factor on the PGA Tour in 2022-2023 was 1.522. You can see current stats here.

What should my smash factor be?

Even though 1.5 is the gold standard for smash factor with a driver, the average golfer’s smash factor is much lower than that. If you can achieve a smash factor higher than 1.45 with your driver, you’re on the right track.

Is a smash factor of 1.45 good?

Yes, a smash factor of 1.45 is good if you’re an average golfer using a driver. Professionals and scratch golfers often have a smash factor between 1.49-1.51 with their driver.


  1. “Boosting your swing speed will definitely improve your smash factor”
    This statement in your article is incorrect. Boosting your swing speed, can possibly and will probably increase your ball speed, but is not a factor in improving your smash factor. Based on our data, the average amateur, when attempting to swing harder, will decrease their smash factor, due to less Centeredness of Contact.

    1. Hey John – thanks for weighing in! I suppose that sentence could be rephrased to say “boosting your swing speed may improve your smash factor” but as I referenced at several times throughout the article, centeredness of contact or hitting the sweet spot are actually more important than swing speed. As the next sentences in the article point out…

      “If you just try to swing faster, your hits may be less accurate. And as I just mentioned, hitting the sweet spot is really important.”
