Driver loft and shaft flex for 94 mph
For these fitting references, speed is converted to mph and rounded to the nearest whole mph. At a shared endpoint, the higher-speed band is highlighted.
Driver loft
9–11°
Slower swings need more loft to get the ball high enough to carry. Most drivers are sold at 9°, 10.5° or 12°, and an adjustable hosel moves that a degree or two.
| Swing speed | Loft |
| Under 70 mph | 12–15° |
| 70–80 mph | 11–13° |
| 80–90 mph | 10–12° |
| 90–100 mph | 9–11° |
| 100+ mph | 8–10° |
Shaft flex
Stiff (S)
Typical driver shaft weight for this speed: 60–75 g. Flex labels are not standardized between brands, and a quick transition can call for a stiffer shaft than speed alone suggests. Light flex is often labeled A or Senior.
| Swing speed | Flex |
| Under 70 mph | Women's (L) |
| 70–80 mph | Light (A) |
| 80–90 mph | Regular (R) |
| 90–105 mph | Stiff (S) |
| Over 105 mph | X-Stiff (X) |
