Which driver loft suits you: the numbers instead of the rule of thumb
Nine degrees is not a badge of honour. Tour data show that slower swings must launch higher, and the adjustable hosel does the rest.
Hardly any number in golf is read as wrongly as driver loft. Nine degrees counts as the loft of good players, twelve as the one for beginners. The data from both professional tours say the opposite, and they say it clearly.
The tour does not launch flat
TrackMan publishes the driver averages for both tours (launch angle, attack angle):
| Value | PGA Tour | LPGA Tour |
|---|---|---|
| Club head speed | 115 mph | 96 mph |
| Launch angle | 10.4 degrees | 12.6 degrees |
| Spin | 2'545 rpm | 2'506 rpm |
| Attack angle | minus 0.9 degrees | plus 2.8 degrees |
Two rows are the whole lesson. The women swing 19 mph slower and still launch more than two degrees higher. And they strike the ball upwards, at plus 2.8 degrees, while the men strike slightly down at minus 0.9.
Why slower needs more loft
A ball flies far when it launches high enough to stay in the air and spins little enough not to climb. At high speed the height arrives almost by itself, because ball speed and spin carry the ball. At low speed that lift is missing, and the angle has to replace it.
So the rule of thumb is simple and the opposite of intuition: the slower you swing, the more loft you need. Play a 9-degree driver at 85 mph and you lose carry without noticing, because the ball launches flat and drops early.
Attack angle is half the answer
Whether the club head is moving up or down at impact changes the launch as much as loft itself. Struck upwards the ball launches higher with less spin and flies further; struck downwards it launches flatter with more spin.
A player with plus 3 degrees of attack angle can do well with 9 degrees of loft. The same player at minus 3 needs 11 or 12. The number appears on every launch monitor, and it is the reason two players of the same speed play different drivers.
What is in the shop today
A current driver comes in three lofts, 9.0, 10.5 and 12.0 degrees, and each is adjustable by plus or minus 1.5 degrees (PING). That means the 10.5 covers 9.0 to 12.0 degrees, and the 12 reaches 13.5.
In practice most amateurs therefore need exactly one head, the middle one, and then adjust it. If you are unsure, buy 10.5 and you have room in both directions. Buy 9.0 and you can only go up to 10.5, which for many is not enough.
Loft, spin and the adjustable hosel
More loft brings more launch angle and more spin at the same time. With a driver too much spin is a problem, because the ball climbs and lands steeply; the tour sits around 2,500 rpm. Anyone already spinning a lot does not solve a flat flight with loft but with the strike.
On an adjustable hosel, changing loft often changes lie as well, and with it the start direction. That is not a side effect but a second tool: anyone missing right can improve both with more loft and a closed setting.
The test that takes an hour
Book a bay with a launch monitor and bring your own driver. Hit ten balls in the standard setting, then ten at plus 1.5 degrees, then ten at minus 1.5. Note launch angle, spin and carry per series, and drop the best and worst shot.
The right setting is the one with the greatest carry at equal or smaller dispersion. Not the one with the single longest shot, and not the one that feels best. What the numbers mean is in Understanding launch monitor numbers.
The most common mistake
A second-hand 9-degree driver, bought because it was cheap. It has the previous owner's loft and shaft, and both are unlikely to fit. Anyone buying used should take an adjustable head, because then at least the loft can be corrected.
The second most common mistake is changing loft to cure a slice. A slice comes from face angle relative to club path, not from loft. How to find it with numbers is in Correcting a slice with numbers.
What the shaft changes about loft
A softer or lighter shaft bends forward more before impact and effectively adds loft while doing so. Two drivers with the same printed loft therefore launch differently if their shafts differ, and that is one reason a loft without a shaft specification says little.
In practice: never change loft and shaft at the same time, or you will not know which one worked. What the shaft designations mean and why they are not a standard is in Regular, stiff or senior.
Loft and ball choice belong together
A firm ball that your speed does not compress enough launches flatter and takes less spin. Raising the loft to get height solves only half the problem; the other half is the ball.
So test both in the same hour: two loft settings with the same ball, then the winning setting with two balls. Which ball suits which speed is in Which golf ball suits you.
Ball position is free
Before buying loft, move the ball forward in your stance, towards your lead foot, and tee it a little higher. Both catch the ball later in the arc and therefore on the way up, which is exactly what the higher loft was meant to achieve.
The effect is visible on a launch monitor immediately: attack angle rises, launch angle rises, spin falls. Anyone who can change those three numbers in ten shots needs no second driver head, just a setting on the adjustable hosel (PING).
The same thought applies to fairway woods
What holds for the driver holds one step further along too: anyone struggling to get a 3 wood up off the ground takes a 5 wood or a long hybrid. Ping's hybrids start at 17.0 degrees and cover the range where only a wood used to sit (PING).
The reason is the same as with loft: at low speed the lift is missing, and more angle replaces it. Which club suits you in that range is settled in Iron or hybrid.

What to remember
Below 90 mph: 10.5 degrees or more. Above 100 mph with an upward strike: 9.0 to 10.5. In between: 10.5 and the adjustable hosel. Those three lines are as accurate as a rule without measurement can be.
It gets more accurate with an hour in a bay, and that costs between CHF 39 and 79. What a full fitting adds is in Golf fitting in Switzerland; a venue with a launch monitor is on the map.
Frequently asked questions
Nine or 10.5 degrees of driver loft?
For most amateurs 10.5. A current driver adjusts by plus or minus 1.5 degrees, so the 10.5 covers 9.0 to 12.0. The 9 only reaches 10.5 upwards, and for many that is not enough.
Do I need more loft if I swing slower?
Yes. At lower speed the lift from ball speed and spin is missing, and launch angle has to replace it. The LPGA Tour swings 19 mph slower than the PGA Tour and still launches more than two degrees higher.
What does attack angle have to do with loft?
It changes the launch as much as loft does. Struck up, the ball launches higher with less spin; struck down, flatter with more. The PGA Tour strikes the driver at minus 0.9 degrees, the LPGA Tour at plus 2.8.
Does more loft fix a slice?
No. A slice comes from the face angle relative to the club path. More loft raises the ball and can soften the curve slightly, but it does not address the cause. Changing the lie setting helps more than loft does.
How do I test the right loft?
In a bay with a launch monitor, three series of ten balls: standard setting, plus 1.5 degrees, minus 1.5 degrees. Note launch angle, spin and carry, drop the best and worst shot, and take the setting with the greatest carry.
