Question 1

What is a good reaction time?

Accepted Answer

For a simple visual reaction time test, many adults land around 200 to 300 milliseconds. Under 200 ms is fast, while results above 300 ms can be affected by fatigue, distraction, device lag, or input delay.

Question 2

How accurate is an online reaction time test?

Accepted Answer

Browser tests are useful for comparing your own attempts, but your display refresh rate, mouse or touchscreen latency, browser load, and device performance can add delay.

Question 3

How can I improve my reaction time?

Accepted Answer

Practice in short sessions, sleep enough, reduce distractions, use a low-latency input device, and compare results on the same device for fair progress tracking.
