Online Reaction Time Test (ms)
Measure the time delta between visual stimulus onset and your mouse click or screen tap. Evaluate your neuro-motor response time against global benchmarks.
Click to start
When the screen turns green, click as fast as you can!
How to use
- Click the red area to begin waiting state.
- Keep your eyes fixed on the screen.
- Click immediately when screen turns bright green.
- Complete 5 successive attempts to compute average reaction latency.
Human Reflex Benchmark Standards
Global human median visual response: 215–250 milliseconds.
Pro esports players & athletes: 160–190 milliseconds.
Fatigued reflex threshold: 300+ milliseconds.
Hardware & Biological Variables
Display refresh rate (144Hz/240Hz decreases display latency).
Input device polling rate and mechanical click travel.
Physical alertness, sleep deprivation, and circadian rhythms.
Frequently Asked Questions
What is a good reaction time?
Under 200 ms is considered elite, while 200–250 ms is standard healthy human average.
Can you train to improve reaction time?
Yes, focused stimulus-response drills can shave off 20 to 40 ms through neural pathway optimization.
Why does early clicking trigger a fault?
Anticipatory guessing invalidates reaction time measurement.
Do touchscreens add latency?
Yes, mobile touch sensors typically add 20–40 ms compared to wired mechanical gaming mice.
