Free tennis timer for between-point and changeover intervals. ITF rules: 20 seconds between points, 90 seconds on changeovers. Train at regulation pace.
ITF Rule 29: players have 20 seconds between points on serve. This begins from the end of the previous point. The 20-second rule applies when the server is ready and the receiver is ready — both must be prepared. ATP/WTA matches use shot clocks visible to players since 2018.
90 seconds on odd-game changeovers in the first set and onward. 120 seconds at the end of a set. In tiebreaks: changeover every 6 points, 90 seconds. During this time players can sit, towel off, receive coaching (ITF Regulations vary), and hydrate.
Yes. First violation: warning. Second violation: point penalty. Third violation: game penalty. Severe or repeated violations can result in default. At professional level, the shot clock has automated enforcement. At recreational level, the rule is often unenforced but training within it improves match readiness.
Training within regulation time limits builds the mental reset routine needed in matches. Players learn to use exactly 20 seconds productively — towel, bounce the ball, breathe, visualise the next point — rather than stalling or rushing. Consistent pre-serve routines reduce double faults and unforced errors.
Best of 3 sets: 60–120 minutes for men, 60–90 minutes for women. Best of 5 sets: 120–180 minutes average, with some Grand Slam matches exceeding 5 hours. Clay court matches average 15–20% longer than hard court due to longer rallies and slower surface speed.
