Spin Rate
How fast the ball rotates around its axis, measured in revolutions per minute (RPM).
Full Definition
Spin rate is the rotational speed of the golf ball immediately after impact. Backspin creates lift that keeps the ball in the air longer, while also creating drag that slows the ball. Too much spin launches the ball high and causes it to "balloon," losing distance. Too little spin causes the ball to fall out of the sky quickly.
Optimal RangeGeneral guidance based on tour averages. Your optimal range depends on swing speed, physical attributes, and individual technique. Many golfers succeed with metrics outside these ranges.
Driver: 2000-3000 RPM | 7-iron: 6000-7500 RPM | Wedges: 8000-10000 RPM
Why It Matters
Spin rate is the other half of the launch window. Combined with launch angle, it determines your shot's trajectory. Low spin with low launch = knuckleball. High spin with high launch = balloon ball. The goal is optimizing both for maximum carry.
Related Terms
Spin Loft
The difference between dynamic loft and attack angle, which determines spin rate.
Launch Angle
The vertical angle at which the ball leaves the clubface.
Landing Angle
The angle at which the ball descends when it lands.
Dynamic Loft
The actual loft of the clubface at impact, which differs from the club's stated loft.
Spin Rate Type
Indicates whether the spin rate was directly measured or calculated from other data.
