Loft affects how high the ball launches and how much spin it has.
For drivers, common lofts include:
9°: Lower launch, less spin — better for fast swing speeds
10.5°: Balanced launch and spin — works well for most golfers
12°: Higher launch, more spin — great for slower swing speeds and a common choice for many female golfers
Choosing the right loft helps optimize distance and consistency based on how you swing.
