Do Longer Shafts Increase Distance? What the Tests Show About Driver Length

Usually a little, but not as much as you'd think. A longer driver shaft tends to add some clubhead speed, because the head travels through a bigger arc. The problem is that a longer club is also harder to hit in the middle of the face, and off-center hits take back most of the speed you gained. In the tests we found, the gains were small and the results were mixed: some golfers gained a few yards, others lost distance and hit the ball more offline. Length can make a real difference to your game. It's a trade between speed and control, and where you land depends on how well you strike the ball.

Why a longer shaft should add speed

The idea is simple. If you swing a longer lever at the same pace, the end of it moves faster. Add a couple of inches to a driver and, in theory, the head arrives at the ball with more speed. More clubhead speed means more ball speed, and more ball speed means more distance. This is why long-drive competitors play drivers at or near the legal limit of 48 inches.

Where the idea runs into trouble is the word "theory". It assumes you swing the longer club at the same pace and hit the ball in the same spot on the face. Most golfers can't do both.

What the tests actually show

There isn't one perfect study, so here is what several tests found when they compared a standard-length driver with a longer or shorter one.

A few things stand out. Clubhead speed went up in almost every test, but usually by only one or two miles per hour. Distance moved a few yards either way, and the shorter club was often the more accurate one. The Miles of Golf testers also noted that they "did not see a consistent 1 mph increase in speed" for each inch of length. Estimates of how much speed an extra inch adds vary a lot. Club physics writer Dave Tutelman's own analysis gives anything from about half a mile per hour to nearly two.

Don't read too much into any one row. The tests are small, from 1 to 37 players, and several are more than ten years old. A 2008 lab study of seven near-scratch golfers (Kenny, Wallace and Otto, in Sports Biomechanics) found the same pattern for ball speed, which rose with length, but the extra carry wasn't statistically significant.

Why extra speed doesn't always turn into extra distance

A one or two mile per hour gain is worth only a few yards. As a rough guide, one mile per hour of swing speed is worth about two yards of carry. That small gain is easy to lose.

The reason is where the ball meets the face. A longer shaft makes the club harder to control, so you hit more shots toward the toe or heel. A Titleist research executive told Golf Digest back in 2010 that it becomes "exponentially more difficult" to find the center of the face with a longer shaft. Robot testing shows how fast a miss costs you. In Golf Digest's 2026 test at 95 mph, a hit 0.75 inch toward the toe lost about 5 yards, and a heel hit lost 12 to 15 yards. Those numbers change from driver to driver, but the point holds. One slightly off-center strike can cancel the yards a longer shaft just gave you.

That's also why the shorter club kept coming out tighter in the tests above. If your best drives are already hit on the center, extra length may help. If your misses come from the toe or heel, it will probably make them bigger.

What do tour players and the rules say?

The best players in the world aren't playing 48-inch drivers. Most major-brand drivers ship at 45.5 to 45.75 inches. Titleist's GTS drivers are 45.5, Callaway's Quantum Max and TaylorMade's Qi4D are 45.75, and PING's G440 is 45.5 or 46 depending on the shaft. Compare that with what the pros play:

• Scottie Scheffler: 45 inches, according to August 2026 reports from GolfWRX and Golf.com.

• Rory McIlroy: about 45⅝ to 45¾ inches in his April 2026 Masters bag, depending on the source.

• Xander Schauffele: 45.5 inches, according to a 2025 GolfWRX report.

• Bryson DeChambeau: said in 2020 that he'd use a 48-inch driver "if I could control it", then played 45.5 inches. Later reports put his driver between 45¾ and just under 46 inches.

One long-drive champion tells the same story. Kyle Berkshire plays a 48-inch driver in long-drive events and a 45-inch version on the course. Length helps when speed is the only goal. When you need to put the ball in play, even he goes shorter. Lengths in tour bag reports can differ slightly depending on how they're measured, and a 2019 Golf.com report put the Tour average at about 44.75 inches. That figure is old, so treat it as a rough guide.

As for the rules, a driver can't be longer than 48 inches under the Equipment Rules. Since January 2022, the USGA and R&A also offer an optional local rule that limits clubs to 46 inches for professional and elite events, and the PGA Tour adopted it. At your home course, 48 inches is still the limit.

Can driver shaft length make a difference to your golf game?

Yes, and it can go either way. Here's what the tests suggest.

A longer shaft can help a golfer who already finds the center of the face and has a tempo that handles the extra length. The speed gain is real, but small. It helped the slowest swinger in the Miles of Golf test the most (about 1.9 mph) and the fastest swinger the least. It's less likely to help a golfer who misses toward the toe or heel, or whose misses already spread wide. In the MyGolfSpy test, the senior tester lost about 5 yards of carry with the longer club.

A shorter shaft can give up a bit of speed in return for a tighter pattern. In several tests that trade paid off, with the same carry and fewer misses. The best result in the Miles of Golf test came from the 44.5-inch club for accuracy, and the extra yard of carry from the longer one wasn't worth the wider spread.

We looked for measured data linking driver length to a golfer's height and found none, so we're not going to give you a "taller means longer" rule. The honest answer is that it varies from golfer to golfer, and the fastest way to find yours is to test it.

How to test your own driver length

If you want to see what length does for you, test it the way the studies did, with a few changes. Use the same head and the same shaft model at two lengths, such as 45 and 45.5 inches, or 45.5 and 46. Hit at least 10 solid drives with each. Don't just compare clubhead speed. Compare carry distance, ball speed, how many of your shots finished in the fairway, and where the ball hit the face. Face spray or impact tape shows you in seconds if the longer club is pulling your strikes toward the toe.

Keep in mind that changing the length of a club also changes its swing weight, by a few points for every half inch. A good builder will adjust the head weight to keep the club feeling the same. If the swing weight is off, a club can feel different for reasons that have nothing to do with the length.

Where Steadfast shafts fit

The Jupiter One Driver Shaft is listed at 45.5 inches in every flex, a normal length that suits most golfers. If you think a different length would suit you, ask your fitter or builder before you order, because the length and the swing weight need to be set together. For a list of standard lengths by club, see our standard golf shaft length guide.

The bottom line

Do longer shafts increase distance? A little, for some golfers, and often not at all once you count the extra misses. The speed gain is usually one or two miles per hour, and off-center strikes can wipe it out. The best players in the world play drivers within about an inch of standard, and even a long-drive champion plays a shorter driver on the course. Test two lengths with the same shaft, judge them on carry and where the ball finishes rather than on speed, and keep the length you can hit in the middle.
