What Driver Loft Should You Use? A Loft Grid Indexed to Swing Speed and Attack Angle
Clubhead speed sets the range and attack angle picks the number inside it. Two golfers at 95 mph need roughly 13° of static loft if they hit 5° down and about 10.5° if they hit 5° up, which is a three-degree spread no speed-only chart can see. The grid below gives both, plus the hosel setting that reaches your number from a stock head and the conformance limits the head has to stay inside afterwards.

Find your driver clubhead speed down the left of the grid, find your attack angle across the top, read the loft. If you already know both numbers, skip everything else on this page.
Almost nobody knows the second one. Clubhead speed gets measured at every demo day going. Attack angle gets measured in fitting bays and essentially nowhere else, and it is the variable that decides whether two golfers swinging at the same 95 mph need a 13° head or a 10.5°. Same speed. Three degrees apart. No chart built on speed alone can see that.
What follows is the grid, the sleeve setting that gets you to your number from a stock head, and the limits the head has to stay inside to remain on the conforming register once you have finished adjusting it.
Attack angle, and why the shop never asks
Attack angle is the vertical direction the clubhead is travelling at the moment of impact. Negative is descending. Positive is ascending. On a teed driver you want ascending, and most club golfers do the opposite.
Tour numbers give you the scale. The men's tour average sits around one degree down with a driver. The women's tour average is roughly three degrees up, which is a large part of why LPGA players carry the ball further than their clubhead speed says they should. Recreational men commonly measure two to four degrees down, and a steep minority are worse than that.
Hitting down on a driver costs you twice. Launch angle falls, because launch follows dynamic loft and attack angle together. Spin rises, because spin loft is dynamic loft minus attack angle, so every degree you subtract from attack angle adds a degree of spin loft. Low launch with high spin is the worst pairing in golf: the ball climbs, stalls, and drops out of the air short.
Static loft buys back some of the launch. It does not buy back the spin. That is why the loft cell for a steep player is higher and the target spin number in the same row is still unattractive.

The launch and spin columns are the window a fitter will be steering you into on the monitor, not a pass mark. Cells marked † go back up rather than down — see below. The dagger cells are the ones that look like a typo. At 100 mph and above, a golfer hitting five degrees up with a low-lofted head can drop the spin rate under 2,000 rpm, and below that the ball stops holding its line in the air. The fix at that corner of the grid is more loft, not less. It reads backwards and it is right.
Treat these as starting points for a session, not final answers. Loft is one of three levers, and the other two are head model and shaft. A forward-CG, low-spin head at 10.5° can produce the same spin number as a rearward-CG head at 9°, and no chart can predict which one your delivery prefers.
Getting to your number from a stock head
Almost no driver plays at the loft printed on the crown. Adjustable hosels have been standard for well over a decade, and the sleeve is how you land on a number the grid gives you without hunting for a rare stock head.
Most sleeves cover roughly one and a half to two degrees either side of the stated loft, usually in three-quarter-degree steps. The catch is that a single-axis sleeve cannot separate loft from face angle. Add loft and the face closes. Take loft off and it opens.

If the grid sends you here, buy a dedicated high-launch head instead Use this before you buy, to pick the stock head, rather than afterwards to rescue the wrong one. The face-angle column is why a two-notch sleeve change often feels wrong even when the numbers on screen improve. Two-axis systems avoid the trade. Titleist's SureFit hosel splits loft and lie across two rings so you can add loft without closing the face, and Ping handles lie separately at the build stage. If you are sensitive to how the face looks behind the ball, that separation is worth paying for, and it is one of the few genuinely meaningful differences between adjustable systems.
Write the setting down. Sleeves get knocked out of position during a regrip or a shaft swap, and a driver that suddenly hooks in April is frequently a driver somebody reassembled in the wrong notch.
Below about 2,000 rpm the ball stops flying
There is a floor under this. Backspin is what generates lift on a golf ball, and once the rate drops under roughly 1,800 to 2,000 rpm the ball loses its ability to hold a flight. It knuckles. Carry falls off a cliff and dispersion widens, because a ball with almost no spin axis stability wanders on whatever the face gave it.
The golfers who find that floor are the ones the industry spent fifteen years telling to hit up on it. A 105 mph swing, a genuine +5° attack angle, a 9° head with a forward centre of gravity and a low-spin shaft profile is a combination that can produce 1,600 rpm. It looks superb on the first three shots and then one turns over and never comes back.
If your spin rate is under 2,000 with a driver, the answer is loft, and after that a heavier head weight or a softer-tipped shaft. Take the low-spin head out of the equation before you start adding degrees, because stacking loft onto a head designed to kill spin is an expensive way to end up back where you started.
Where the loft you set actually sits on the conforming register
Adjust a driver far enough and you are no longer holding the club that got tested. That matters less than golfers fear and more than they check.
The head model is what appears on the USGA and R&A Conforming Driver Head List, and adjustable heads are listed with their designed adjustment range. Using the manufacturer's own sleeve inside that range keeps you on the list. Bolting a generic aftermarket sleeve onto a head, or having the hosel bent at a bench, is where the paper trail breaks.

Conformance Grade for a driver build on this site: A means the head is on the register, the sleeve is the original, the finished length is inside 46 in and you can point at all three. B is the same build with a length you have never actually had measured. C is a used head with an unbranded sleeve. F is a 47 in build entered into a competition running G-10.
The penalty structure is worth knowing because it is blunt. Making a stroke with a non-conforming club is disqualification under Rule 4.1a. There is no two-shot version of it, no warning, and no partial credit for not knowing.
Reading your own attack angle without paying for it
Book the monitor session if you can. Twenty minutes in a fitting bay gives you a number you can use for the next five years, and attack angle is stable for most golfers unless they rebuild the swing.
Failing that, there are honest proxies. Tee height is the loudest one: golfers who consistently mark the crown of the driver low on the face are almost always descending on it, and those who catch the ball high on the face off a high tee are usually ascending. Divot behaviour with a driver off a mat tells you nothing useful, so ignore it.
Ball position moves the number more than anything else you can change. Shifting the ball from the middle of the stance to opposite the left instep can be worth two to three degrees of attack angle on its own, because you are meeting the ball later in the arc. Adding a little spine tilt away from the target does something similar. Both are free, and both are worth trying before you spend money on a head with a different number stamped on it.
Most owners who go through this process find their measured attack angle is a degree or two worse than they assumed. Fitters report the same thing. Build in that pessimism when you read the grid.
Five ways golfers end up in the wrong loft
- Buying to the number a friend plays. Loft is a delivery-condition answer, and two people with the same handicap can be six degrees apart on it.
- Fitting on a mat with a radar unit that has no room to see the ball. Spin numbers indoors on unmarked balls with a short flight window are frequently the least reliable figure on the screen, and spin is the number loft is being chosen to control.
- Taking loft off to stop a slice. It does the opposite: less loft means less gear effect correction and a more open face at the same sleeve position, so the ball curves harder.
- Chasing ball speed instead of carry. Ball speed is set by strike quality and smash factor, not loft. Loft decides what the ball does after it leaves.
- Setting the sleeve to plus two and never checking the finished length. That combination is how golfers arrive at a build that is closed, upright and over 46 inches, all at once.
Quick answers
- Slower swing, more loft — but only up to about 15°, past which the extra spin costs more carry than the launch gains.
- A 10.5° head is the right default for a golfer between 90 and 100 mph who has never measured attack angle. It is the loft with the most sleeve range in both directions.
- Adding loft with a single-axis sleeve closes the face. If the club starts going left after an adjustment, that is why, and the fix is a weaker sleeve position with a higher-lofted head rather than a lower setting.
- Loft on the crown is nominal. Measured loft on a bench routinely differs from the stamp by up to a degree, in both directions, and no rule requires it to match.
- Nothing in the loft decision affects conformance. Length, sleeve provenance and the pendulum test are the three things that do.
