Understanding Tennis Serve Speed
Tennis serve speed is calculated from the distance the ball travels divided by the time it takes. The standard court baseline-to-baseline distance is 78 feet. Professional serves typically travel from the service line to the receiver, about 60 feet in the air.
Professional men serve at 115-140+ mph, women at 100-125 mph. The fastest recorded serve was 163.7 mph by Sam Groth. Club-level players typically serve 60-100 mph. Serve speed is affected by technique, racket head speed, and contact point.
This calculator provides estimates based on straight-line distance and flight time. Actual serve speed is measured by radar guns at the point of contact. The ball slows significantly due to air resistance, losing about 30-40% of its speed before reaching the receiver.
