How It Works

Tennis Serve Statistics

Serve percentage measures how often a player lands their first serve in play. A high first serve percentage is crucial because first serves are typically hit harder and win more points.

Formula

First Serve % = First Serves In / Total First Serve Attempts x 100

Ace Rate = Aces / Attempts x 100

Elite players make 60-70% of first serves and win 70-80% of first serve points.

Worked Example

A player lands 40 of 60 first serves, with 8 aces and 3 double faults.

first_serves_in = 40first_serve_attempts = 60aces = 8double_faults = 3
  1. 01First serve % = 40 / 60 x 100 = 66.7%
  2. 02Ace rate = 8 / 60 x 100 = 13.3%
  3. 03Double fault rate = 3 / 60 x 100 = 5.0%
