Loft
Driver loft by swing speed
ELDRICK starts driver loft at 12° under 80 mph, 10.5° from 80 to 99 mph and 9° from 100 mph, then moves it with your peak height, landing angle, launch angle and spin. Every speed band has limits: 9° to 12° under 90 mph, 9° to 10.5° from 90 to 104 mph, and 8° to 10.5° from 105 mph.
| Driver speed | Starting loft | Allowed head loft | Launch too high above | Launch too low below | Spin that drops loft one step |
|---|---|---|---|---|---|
| Under 70 mph | 12° | 9°-12° | 17° | 13° | 5,000 rpm |
| 70-79 mph | 12° | 9°-12° | 16° | 13° | 4,600 rpm |
| 80-89 mph | 10.5° | 9°-12° | 15.5° | 12° | 4,300 rpm |
| 90-99 mph | 10.5° | 9°-10.5° | 15° | 11° | 4,000 rpm |
| 100-104 mph | 9° | 9°-10.5° | 15° | 11° | 4,000 rpm |
| 105-109 mph | 9° | 8°-10.5° | 14.5° | 10° | 3,700 rpm |
| 110 mph and up | 9° | 8°-10.5° | 13.5° | 9° | 3,500 rpm |
Head lofts come from 8°, 9°, 10.5° and 12°. Spin 300 rpm above the step-down number (500 rpm under 80 mph, 400 rpm at 70-79 mph) drops loft two steps, never below the band's minimum.

Start with speed, finish with flight
The starting loft is only a default. When ELDRICK has your peak height and landing angle, it compares them to the targets for your speed. Flight too high steps loft down; too low steps it up, within the band's limits. If your flight is already on target and your current loft is legal for your speed, ELDRICK keeps your current loft.
Without peak height or landing angle, launch angle does the job. A launch above the band's high mark sets loft to the band minimum, and one below the low mark sets it to the band maximum. Under 70 mph with a launch in range, ELDRICK still fits the highest loft, because carry is the whole game at that speed.
Two guardrails worth knowing
A 90-99 mph golfer playing 9° gets moved to 10.5° unless measured flight shows 9° is working. It's the most common loft mistake ELDRICK sees in that band.
If your face is open to your path (a push), ELDRICK won't drop loft more than one step from your current driver, because less loft makes a push curve more. The launch monitor guide lists the peak height and landing targets for each speed.
Frequently asked questions
What driver loft should I use at 90 mph?
Start at 10.5°. ELDRICK allows 9° to 10.5° from 90 to 104 mph, and moves you to 9° only when your peak height, landing angle or spin say so.
Should a slow swinger use 12° driver loft?
Yes. Under 80 mph ELDRICK starts at 12°, the highest head loft it fits, and moves down only when flight or spin says so.
Is 9° or 10.5° better at 100 mph?
9° is ELDRICK's starting point at 100 mph and up, and 10.5° is the band maximum. In ELDRICK fittings at 100-109 mph, 52% got 9° and 41% got 10.5°.
Does high spin mean less loft?
Often. Spin at or above your band's step-down number drops loft one step, and 300 rpm or more over it (at 80 mph and up) drops two, never below the band minimum.
