Knee

The standard height from which golf balls must be dropped when taking relief under various rule situations, measured from knee height to ensure consistent drop procedures. Proper drop height ensures balls land appropriately and prevents gaining unfair advantage through relief procedures. Understanding knee-height drop requirements is crucial for proper rules compliance and fair play. Modern golf rules simplified drop procedures by standardizing the knee-height requirement for most relief situations. Proper drop technique includes correct height, location, and procedures that maintain competitive equity.
