Side Deviation

Full Definition

Side deviation (or offline distance) measures how far the ball ends up from the target line, either left (negative) or right (positive). It combines the effects of start line error and curvature. Side deviation is a key measure of accuracy and directional control.

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.

Why It Matters

Side deviation is the accuracy metric that matters most for scoring. Missing fairways and greens costs strokes. Understanding whether your misses come from start line or curvature helps you fix the right thing.
