Professional online mouse reaction time testing tool that measures your visual reaction speed and response accuracy. Perfect for gamers, athletes, and users looking to assess and improve their reaction time performance.
Test your mouse reaction speed and response time accuracy
Click the start button, wait for the color to change from red to green, then click immediately. Do NOT click early - wait for the green signal!
Excellent (< 200ms): Professional athlete level
Good (200-300ms): Above average gaming performance
Normal (300-400ms): Average human reaction time
Needs Practice (> 400ms): Room for improvement
Average human reaction time: 250-300ms
Essential for FPS games, racing simulations, and competitive gaming where split-second reactions determine success.
Used by athletes to measure and improve reaction times for better sports performance and training optimization.
Evaluate cognitive response speed, monitor age-related changes, or assess the effects of fatigue and alertness.
Average human reaction time is 250-300ms for visual stimuli. Under 200ms is excellent (professional level), 200-300ms is good, 300-400ms is average, and over 400ms suggests room for improvement.
False starts occur when you click before the stimulus (green) appears. Stay patient, focus on the test area, and only click when you see the color change to green. Anticipating the timing leads to false starts.
Practice regularly, stay alert and well-rested, maintain good physical fitness, avoid distractions, use consistent technique, and consider specific reaction training exercises for gaming or sports.
Yes, reaction time typically increases with age due to slower neural processing. However, regular practice, physical activity, and maintaining good health can help minimize age-related decline.
Our test provides good estimates for general assessment and training. For precise scientific measurements, specialized equipment is recommended. Results can vary based on browser performance, hardware, and testing conditions.
