Ball Speed
Ball speed is how fast the ball leaves the clubface, measured in miles per hour. It is the single biggest driver of carry distance.
Ball speed is determined by how efficiently the club transfers energy to the ball at impact — a function of club speed and strike quality (see smash factor). A centered strike at a given club speed produces far more ball speed than an off-center one, which is why ball speed, not club speed, correlates most strongly with distance. On a launch monitor it is the headline number for distance potential.
Example — On a launch monitor
A driver club speed of 100 mph with a flush strike yields a ball speed near 148 mph (a 1.48 smash factor).
Why it matters
Chasing club speed without clean contact wastes ball speed. SwingVantage helps you see whether distance is limited by speed or by strike — so you train the right one.

- Club SpeedClub speed is how fast the clubhead is moving just before impact, in mph. It sets the ceiling for ball speed and distance — but only if contact is clean.
- Smash FactorSmash factor is ball speed divided by club speed — a measure of strike efficiency. A driver smash factor near 1.50 means the ball left the face at 1.5× the clubhead speed, the practical maximum.
- Carry DistanceCarry distance is how far the ball travels through the air before it first lands — distinct from total distance, which includes roll.
