What is the average reaction time? On browser-based visual tests, typical results cluster between 200 and 300 milliseconds. Here's how to read that number responsibly — and test your own.

Many people score 200–300 ms for simple visual reactions online. Under 200 ms is very fast; over 300 ms is common and perfectly normal, especially on touchscreens.
Published lab figures differ from online tests because of hardware and software latency. We report your median alongside the average to reduce the effect of outliers, and label all population comparisons clearly.
Yes — 250 ms is a solid, common result on a browser visual test. Practice and a low-latency setup can pull it lower.
It's a benchmark for this specific task, not a medical or intelligence measure. Your own trend over time is the most useful signal.
At least five. One attempt is noisy; a median across five is far more reliable.
ReactionLab is a browser-based reaction performance test. It is not a medical, neurological, or intelligence assessment. Results depend on your hardware, input device, and browser. See our methodology.
