Club Head Speed

The velocity of the club head at impact, measured in miles per hour. Often shortened to "club speed" or "swing speed."

Club head speed is the largest single contributor to distance — every additional 1 mph of club speed typically yields 2.5–3 yards of carry on driver. Tour-average driver club speed is roughly 115 mph; a scratch amateur is around 105 mph; an average male amateur is 90–95 mph.

Combined with smash factor, club head speed determines ball speed. Some launch monitors report only ball speed and infer club speed; others measure both directly.
