The slower the swing, the more loft the driver needs. Under 85 mph the right answer is 11°–13°; between 85 and 95 mph — where most male amateurs sit — it is 10.5°–12°; from 95 to 105 mph it is 9°–10.5°; and only above about 105 mph does a driver lofted under 9° start paying for itself.

Recommended driver loft by swing speed

Speeds are driver clubhead speed, not ball speed. Carry figures assume a reasonable strike; thin and heel strikes shed distance at every speed.

Why slower swings need more loft

Carry distance is launch angle, backspin and ball speed working together. The distance-maximising window for an amateur is roughly a 12°–16° launch with 2,000–3,000 rpm of spin. A fast swing reaches that window with a low-lofted face because sheer ball speed does the climbing; a slower swing launched at 9° comes out low and under-spun, runs out of hang time, and lands 15–20 yards short of the same swing with a 12° face. Loft is how a moderate swing buys the airtime a fast swing gets free.

Adjust for attack angle

The table assumes a roughly level strike. If you hit up on the ball — teeing high, ball forward, driver sweeping upward 3°–4° — you add that much launch and can sit at the low end of your band, or a band lower. If you hit down on it, as most slicers and former iron-first golfers do, move up within the band. A launch monitor reads attack angle directly; ball flight hints at it too, with a low-spinning knuckling drive suggesting up, and a high-spinning ballooning one suggesting down.

Use the hosel to fine-tune, not to span bands

An adjustable hosel moves most current drivers ±1°–2°, which comfortably covers fine-tuning within a band — a 10.5° head plays anywhere from about 9.5° to 12°. What it does not do is turn a tour head into a beginner’s driver: the head’s centre of gravity and face design are built around its stated loft. Buy the loft in the middle of your band and adjust from there; the driver loft chart lists what each brand sells.
