Tennis Serve Speed Calculator

Calculate your tennis serve speed in mph, km/h and m/s, compare it with typical benchmarks for different player levels, and estimate how much reaction time your opponent actually has based on court distance and ball speed.

Serve Speed Player Benchmarks Reaction Time Triple Calculator Modes

Measure Tennis Serve Speed and Reaction Time

This Tennis Serve Speed Calculator offers three modes in one place. First, you can compute basic serve speed from distance and time. Second, you can analyse your serve with player-level benchmarks for recreational, intermediate, advanced and pro standards. Third, you can explore how much reaction time your opponent has when facing serves at different speeds over real court distances.

You can enter distance in either meters or feet. The calculator automatically converts between the two so you can work in whichever unit is more natural for you. Time can be entered in seconds and, optionally, extra milliseconds for more precise timing from video or radar.

Approx. baseline to service box: 18.29 m
Auto-converts from meters and vice versa
Optional – leave 0 if unknown

The calculator assumes constant speed between racket contact and landing in the service box. Real serves slow slightly due to air resistance, so measured speeds from radar guns near impact may be marginally higher than speeds estimated from court distance and timing alone.

Presets use typical singles court geometry

The advanced mode compares your serve speed to simple benchmark ranges for different player levels. These are approximate guidelines and will vary with age, surface, playing style and whether this is a first or second serve.

Reaction time analysis assumes the ball travels the given distance at the stated average speed. In reality, the ball slows slightly, and the receiver anticipates from toss and motion, so these numbers are indicative rather than exact.

Tennis Serve Speed Calculator Inputs

Tennis Serve Speed Calculator uses Distance (meters), Distance (feet), Time (seconds), Extra time (milliseconds), Court distance preset.

Tennis Serve Speed Calculator Formula or Method

  • Flight time (seconds) = Distance (meters) ÷ Speed (m/s)
  • Time (seconds) = Frames ÷ Frames per second = 30 ÷ 60 = 0.50 seconds
  • Speed (m/s) = Distance (meters) ÷ Time (seconds) Speed (km/h) = Speed (m/s) × 3.6 Speed (mph) = Speed (m/s) × 2.23694
