What Flex Should My Driver Be?

One of the best ways to improve your score at golf is to get clubs that are well suited to how you swing. Not every club is excellent for every golfer. Some golfers need a club with more or less flexibility than others.

Whether or not a lot of flexibility is suitable depends on how fast your golf swings are. If you can swing your club very fast, a stiff or extra stiff club with very little flex is best. If your golf swing is slower, use a club with more flex to get the best results.

What Flex Should My Driver Be?

While a club-fitter can help you find clubs that are well suited to you, you should also learn a little about the subject yourself. The more you know, the easier it is to make good purchases.

Shaft flex is how much the golf club bends when you swing it. If there is little shaft flex, even a swift swing won’t make the shaft bend all that much. With more shaft flex, a slower swing will be enough to make the shaft bend.

Shaft flex matters a lot because how much the shaft bends determines how far you can drive the ball and what direction it goes in.

You will get quite noticeably worse results if your club has too much flex or too little. On the other hand, if your club is too flexible for your swing speed, the club will bend too much, and you will not have much control over where the ball goes.

What flex should my driver be?

If you know your swing speed, you can determine how much flex you need in a club. All golf clubs bend to some extent – a golf club is never completely rigid. Clubs are given the following ratings, from most rigid to most flexible:

  • XS – Extra stiff
  • S – Stiff
  • F – Firm
  • R – Regular
  • A – Amateur / Senior
  • L – Ladies

Unfortunately, different companies have different standards. A club that one company rates as a firm are not always more rigid than another company rates regularly. Swing speeds are also not always categorized in the same way.

To know what club you need, you should measure your golf swing speed. If you plan to buy a driver, measure your speed with a driver, not with another type of club.

Your speed with one type of club is not the same as your speed with another. One can swing a driver significantly faster than one can turn a six iron. A driver will give you the quickest swing, followed by a 3-wood, 3-iron, and 6-iron.

Golf swings range from under 65 miles per hour for new golfers to more than 110 miles an hour for powerful swingers. With a driver, a speed over 105 miles per hour is considered very fast. However, your swing speed can also be short (97-104 miles per hour), average (84-96 MPH), slow (72-83MPH), or ladies (Under 72 MPH).

Based on your swing speed, you can choose a driver with the proper shaft flex. The rates line up with the ratings for stiffness:

  • Very fast – Extra stiff
  • Fast – Stiff
  • Average – Regular
  • Slow – Amateur/Senior
  • Ladies – Ladies

Not everyone agrees on how to categorize swing speeds. According to some, you should have a swing speed of 110 miles per hour before switching to a different stiff club. You can use numbers to narrow your search down, but you might still have to try a few other clubs.

There is no guarantee that you will like any club that lines up with your measured swing speed. In addition, not every company has the same standards when categorizing its clubs.

You may also find that you do better with a somewhat more rigid or flexible club than what your swing speed implies you need.

However, choosing golf clubs based on swing speed works, though it is not an exact science. At the same time, you might like a club that is theoretically a bit too rigid or too flexible. You are not going to want a club that is for someone with a vastly different swing speed.

With this information, you can significantly narrow down your search for a perfect club.

What flex should I use on my driver?

Going with a club that is a bit stiff, even if you do not have a very high swing speed, can be a good idea. Going with a more flexible club also has its advantages. The best shaft flex for your irons might be different from the shaft flex for your driver.

Many golfers choose between stiff and regular flex. These two options are suitable for people with typical or somewhat above-average swing speeds.

Should I use stiff or regular flex?

It may depend on whether you need more distance or more accuracy. Try switching to a stiffer club if you are hitting the ball a long way but not managing to control where the ball goes.

A stiffer club won’t bend too much when you swing it, which will make you much more accurate. If you want to hit the ball as far as possible, go with a regular rather than a stiff club.

Graphite, Titanium, and Steel

Not all golf clubs are steel. You can find Titanium clubs and Graphite clubs as well, and these clubs are lighter, so you can swing them faster.

It doesn’t make a huge difference – for example, someone might hit the ball 210 yards with a titanium club instead of 200 yards with a steel one. Also, the material might not have very much of an effect on your swing speed, so it might not affect what shaft flex you need.

How far can you hit the ball?

You can determine what flex you need based on how far you can hit the ball and not only how fast you can swing.

Go with a regular flex if you can hit the ball anywhere from 200 to 240 yards at the driving range. If you can plug it 240 to 275 yards, you can swing hard enough that a stiff flex is probably better.

You can estimate what type of driver you need from your carry distance:

  • Under 180 Yards – Ladies
  • 180 to 200 Yards – Senior
  • 200 to 240 Yards – Regular
  • 240 to 275 Yards – Stiff
  • Over 275 Yards – Extra stiff

Other considerations

There are many other things you need in a club besides shaft flex. Of course, shaft flex is one of the most important things, but there are other reasons why a club might not be very well suited to your swing.

Shaft kick point

While shaft flex is how much the club bends, the shaft kick point is the part of the club that turns the most. Where the club bends the most is also relevant. The club’s shaft point affects the ball’s trajectory.

Some clubs have a high shaft point, so they bend the most near the top where you grip it. The ball won’t fly nearly as high with a high shaft point. Use a high shaft point if you want a flatter trajectory.

If you want the ball to ark into the air as high as possible, on the other hand, then a lower kick point is the best idea. The lower the kick point, the higher the ball goes.

Usually, higher kick points and lower trajectories are better for more experienced players with faster swing speeds. An expert usually wants a flat course because they can be more accurate that way. On the other hand, if the ball goes too high, it is harder to control.

A beginner might be better off with a lower kick point because they can hit the ball farther that way. However, suppose they are not experienced enough to worry about excellent accuracy. In that case, a lower kick point will help them hit the ball higher and farther.

Somewhere in the middle is usually the best. It would help with a kick point that is only a little lower or higher than average. Not very many golfers want unusually high or unusually low kick points.

Club length

Even someone who has never gone golfing before could tell if a club is too short or too long for their height. Therefore, it is the most basic and obvious thing to consider when buying a new club.

Your posture won’t be any good with a club that is too long or too short. You will bend over too much if the club is too short and not bend forward enough if the club is too long. Poor posture will lead to a weaker and less accurate golf swing.

Golf clubs do not vary in length by nearly as much as people vary in height. A tall person who is more than six feet eight will need a club only two inches longer than average, and someone less than four feet ten a club only two inches shorter.

A golf club of standard length is good for people from five feet seven to six feet one. Everyone out of that range, especially more than a little out of that range, is best with a shorter or longer club:

  • Over 6’8″ – 2 inches longer than standard
  • Over 6’6″ – +1.5 inches
  • Over 6’4″ – +1 inches
  • Over 6’2″ – +0.5 inches
  • Over 6’1″ – +0.25 inches
  • Between 5’7 and 6’1 – Standard
  • Under 5’7″ – 0.25 inches shorter
  • Under 5’4″ – 0.5 inches shorter
  • Under 5’2″ – 1 inch shorter
  • Under 5′ – 1.5 inches shorter
  • Under 4’10” – 2 inches shorter

You can also use the distance from your wrist to the ground to determine the length of the club you need. Again, it works at least as well as height.

Someone with a wrist-to-floor measurement of 34 inches or 37 inches is best with a regular size club. A very tall person that needs a club 2 inches longer than usual might have a wrist-to-floor measurement of 42 inches.

Is stiff flex suitable for beginners?

Usually, a beginner has a slower swing speed than an experienced golfer. However, some new golfers are stronger and more athletic than others. If you can already swing a golf club very fast despite having little experience, you might go with a stiff shaft right from the start.

If you have played a lot of hockey or baseball before, you might be able to swing a golf club very fast right from the start. But, of course, experience in some other sports helps you, as does overall strength and fitness.

However, most beginner golfers are not going to benefit from a stiff shaft. A regular post will work better because you can hit the ball farther with a more flexible stick. However, once your swing speed builds up, you should switch to a stiffer shaft.

Are all of a golfer’s clubs always the same stiffness?

No, a golfer might carry some stiffer clubs as well as some more flexible clubs.

A golfer might use a stiffer shaft on their driver than on their other clubs. Golfers love their gear and may collect a lot of different clubs over the years.

What happens if the shaft is not stiff enough?

If the shaft is not stiff enough, your accuracy will suffer. If the shaft bends too much, the club’s head will contact the ball improperly, which hurts accuracy.

If your club bends too much, the golf ball may fly too high, much higher than the club’s loft would suggest. If the ball flies too high, it might not fly far enough. Using a shaft that is too flexible with a club with many lofts can hurt your distance.

Many golfers use clubs with too little loft instead of too much. A more flexible club can help your distance in that case, as the trajectory should be somewhere in the middle and not too high or too low if you want to hit the ball as far as possible.

However, the usual result of using a shaft that is not stiff enough reduces accuracy.

Many golfers use clubs that are too stiff rather than too flexible, which hurts their distance. Don’t insist on a rigid or extra stuffy club if your swing speed isn’t fast enough for that stiffness. Instead, use a regular club until your swing speed improves.

There are many other things to consider – the club’s loft angle and weight can also affect your swing. So it may seem not very easy at first.

The two most important things are the length of your club and the shaft flex. If you talk to a club-fitter, they can help you find a great club for you even if you do not yet know about golf clubs in detail.
