Sidespin
The sideways rotation of the ball that causes it to curve left or right.
Full Definition
Sidespin is the component of ball rotation that causes the ball to curve during flight. It's created by the face-to-path relationship at impact. Right sidespin causes the ball to curve right (fade/slice); left sidespin causes it to curve left (draw/hook). Sidespin combines with backspin to create the total spin rate and spin axis tilt.
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.
Less than 500 RPM for straight shots; 500-1500 RPM for intentional curves
Why It Matters
Sidespin determines how much your ball curves. High sidespin creates big curves that are hard to control. Understanding your sidespin helps diagnose whether curvature comes from face angle, path, or both. Reducing unwanted sidespin is key to hitting straighter shots.
Related Terms
Spin Rate
How fast the ball rotates around its axis, measured in revolutions per minute (RPM).
Backspin
The backward rotation of the ball that creates lift and affects trajectory.
Spin Axis
The tilt of the ball's spin axis, which determines curvature direction.
Face-to-Path
The difference between face angle and club path, which determines curvature.
Curvature
The amount the ball curves in flight from start line to finish.
