Serve speed is one of the most important measurements in tennis, and it can change the dynamics of a match — a faster serve can win free points and push the returner off the court.
But remember, serve speed alone is not everything: spin, placement, and timing also decide outcomes. If you are a player, coach, or fan who wants to calculate tennis serve speed, you have come to the right place.
We bring you a Tennis Serve Speed Calculator that helps you accurately and quickly convert distance and time into speed.
In this guide we cover:
Let's walk through it step-by-step so you understand how it works with an example.
A Tennis Serve Speed Calculator is a tool designed to help you calculate serve speed — that is, how fast the ball was traveling based on distance and time. The result is shown in miles per hour (mph
) or kilometers per hour (km/h
).
Here is how it works:
Are you wondering how exactly tennis serve speed is calculated? Don't worry — we'll walk you through the formula involved:
Here is the formula:
Ball Speed = Distance / Time
This shows that the speed of the tennis ball is the distance it traveled divided by the time it took to travel that distance.
Unit conversions used in the Tennis Serve Speed Calculator:
Let's see a real-world example that will help you understand tennis serve speed calculation.
Imagine a player hits the ball and it takes 0.25 s
to travel 60 ft
before the first bounce.
Distance = 60 ft
Time = 0.25 s
Convert distance to meters (we know the formula works in seconds and meters):
60 ft × 0.3048 = 18.288 m
Now apply the formula:
Speed = 18.288 / 0.25 = 73.152 m/s
Convert to miles per hour (mph):
73.152 × 2.23694 = 163.64 mph
Hence, the serve speed is ≈ 163.64 mph
.
Good serve speed depends on the player’s skill level and gender. Typical benchmarks:
60–90 mph
90–110 mph
120–145+ mph
100–125 mph
