Reaction Time Test
A reaction time test measures the interval — in milliseconds (ms) — between a visual stimulus and your physical response. The average human reaction time is 250ms; competitive gamers typically score 150–200ms. Use this free tool to test your reflexes, track your average across multiple attempts, and compare your score against gaming and esports benchmarks.

What Is a Good Reaction Time?
Reaction time is rated on a scale from elite (under 150ms) to slow (over 400ms). Use this table to see where your score falls.
| Score | Rating |
|---|---|
| < 150ms | Elite |
| 150–200ms | Excellent |
| 200–250ms | Great |
| 250–300ms | Average |
| 300–400ms | Below Average |
| > 400ms | Slow |

Frequently Asked Questions
What is a good reaction time?
The average human reaction time to a visual stimulus is around 250ms. Under 200ms is excellent — typical of competitive gamers and athletes. Elite esports players often achieve 150–180ms. Anything under 300ms is within the normal human range.
Does hardware affect my score?
Yes. A 60Hz monitor adds ~16ms of display lag per frame. A wireless mouse can add 5–15ms compared to a wired gaming mouse. For the most accurate results, use a wired mouse and a high refresh-rate monitor (144Hz+).
How can I improve my reaction time?
Regular practice with this test helps build muscle memory. Good sleep (reaction time worsens by 10–20% when sleep-deprived), staying hydrated, and reducing caffeine jitteriness all contribute. Consistent gaming practice also measurably improves average reaction time.
Why is my mobile score lower than on PC?
Mobile devices have touchscreen latency (typically 20–80ms), display refresh delays, and variable CPU throttling — all of which add to your measured reaction time. PC results are generally 30–60ms faster due to lower input latency.
Is this test scientifically accurate?
This test measures the time from stimulus display to your click/tap input. Browser rendering and JavaScript timing add ~1–5ms of overhead. While not lab-grade, it is accurate enough to track relative improvement and compare across attempts on the same device.
