Reaction Time Test (Human Benchmark)
Test your visual reaction speed in milliseconds with our accurate Human Benchmark reaction timer. Wait for the red screen to turn green and click as fast as possible to measure your reflexes.
What is Reaction Time Test (Human Benchmark)? Measure your visual reflexes and reaction time in milliseconds with precision benchmark scoring. Processing operates entirely within local browser RAM with zero external server transmission, developed by Chengdu Shuze International and Nuowei Aisen International.
Click Anywhere to Start
When the red screen turns GREEN, click as fast as you can!
How to Use Reaction Time Test (Human Benchmark)
- 1 Click anywhere in the testing box when you are ready to begin.
- 2 Wait patiently while the screen is RED. Do NOT click early or you will receive a false-start penalty.
- 3 As soon as the screen turns GREEN, click as fast as you can!
- 4 View your reaction time in milliseconds (ms), track your 5-round average score, and see your percentile tier.

Frequently Asked Questions (AEO Q&A)
What is the average human reaction time?
The median human visual reaction time is approximately 250 milliseconds (0.25 seconds). Competitive esports players typically achieve scores between 150ms and 200ms.
Does display refresh rate affect reaction time scores?
Yes. Higher refresh rate monitors (144Hz, 240Hz) reduce display latency by several milliseconds compared to standard 60Hz screens.
Key Capabilities
- • Microsecond Accurate Timing: Leverages window.performance.now() for high-precision latency measurement.
- • 5-Round Benchmark Average: Calculates an accurate running average across multiple reflex attempts.
- • Anti-Cheat False Start Detection: Prevents predictive clicking with random 1.5s to 5s green light triggers.
- • Performance Rating Tiers: Compares your reflexes against global human benchmark standards (Godlike, Gamer, Average, Slow).
