Launch Angle is the angle, measured in degrees, at which the ball leaves the club face relative to the ground. This is not the full trajectory or the angle to the peak trajectory—it’s specifically the angle in the first few inches of flight, before lift force or gravity has a chance to modify the ball’s path.
Launch angle, sometimes referred to as "Initial Path," is primarily a measurement of vertical launch, not direction. Launch Direction is the horizontal angle relative to the target line of the golf ball's center of gravity movement immediately after separation from the club. Golf club launch angles vary significantly based on both the club type and swing dynamics. Tracking golf launch angle by club can help players and fitters fine-tune performance, dialing in carry distance and optimizing ball flight across different clubs.
