Tennis is a game of tiny margins, and the numbers behind it can flip what you thought you knew. From Hawk-Eye accuracy down to 2.6 mm to electronic line judging rolled out at the 2025 Australian Open, accuracy has never looked so measurable. Alongside the sport’s biggest title streaks, we also track how often finals swing, how surfaces shape rallies, and how today’s players stack up against legends.
