What is ball speed in golf, and how does it relate to club speed and smash factor?
In plain language, what does "Ball Speed" mean on my monitor or export?
Ball speed is the velocity of the ball immediately after impact. It's the result of club speed, contact quality (smash factor), and club design.
Units: mph
Why does this metric matter for ball flight, dispersion, or scoring?
Ball speed directly drives distance. It's the most reliable predictor of carry. Improving ball speed—through better contact or more club speed—is the primary lever for distance gains.
What is a typical or competitive range for this stat?
Driver: 140-170 mph. 7-iron: 110-125 mph. Ball speed is typically 1.3-1.5x club speed for irons.
What usually makes this number look bad or noisy in real rounds?
Low ball speed with high club speed = poor contact (low smash). Off-center hits lose significant speed.
