Is my reaction time good?
You just took a test and got a number. Is it any good? Type your milliseconds in below for an instant verdict, your percentile against millions of online results, and the context most tests never give you.
Tip: this rates a score from an online click test. Haven't got one yet? Take the 10-second test.
What counts as a good reaction time?
Here is the short answer, for an online click test like ours: anything under 250 ms is quick, under 200 ms is genuinely fast, and the typical result sits around 273 ms. If your number is in the 260s or 270s, you are right in the normal range, not slow. The bands below are the ones we use to rate your score above, based on where millions of online results actually fall.
| Reaction time | Verdict | What it means |
|---|---|---|
| under 180 ms | Elite | Pro-tier reflexes, top fraction of a percent. |
| 180–210 ms | Exceptional | Faster than almost everyone. Genuinely sharp. |
| 210–240 ms | Fast | Well above average, quicker than most people. |
| 240–280 ms | Above average | A solid, healthy reaction time. |
| 280–320 ms | Average | Right around the typical online result. |
| 320–400 ms | Below average | A bit slower. Fatigue or device lag usually explains it. |
| over 400 ms | Take another go | Often tiredness or device lag, not biology. Try again rested. |
Is 150, 200, 258 or 300 ms good? Number-by-number
Most people search a specific figure, so here is a straight lookup from 150 to 600 ms on the online-test scale: the verdict and roughly what share of people you would be beating. The seconds column is there because plenty of tests report 0.25 s rather than 250 ms. Find your number, or use the checker above for the exact reading. For the full curve, see the reaction time percentile table.
| Reaction time | In seconds | Verdict | Faster than |
|---|---|---|---|
| 150 ms | 0.15 s | Elite | 99.6% of people |
| 160 ms | 0.16 s | Elite | 99.2% of people |
| 170 ms | 0.17 s | Elite | 98% of people |
| 180 ms | 0.18 s | Elite | 97% of people |
| 190 ms | 0.19 s | Exceptional | 94% of people |
| 200 ms | 0.20 s | Exceptional | 89% of people |
| 210 ms | 0.21 s | Exceptional | 84% of people |
| 220 ms | 0.22 s | Fast | 78% of people |
| 230 ms | 0.23 s | Fast | 72% of people |
| 240 ms | 0.24 s | Fast | 65% of people |
| 250 ms | 0.25 s | Above average | 60% of people |
| 260 ms | 0.26 s | Above average | 55% of people |
| 273 ms | 0.273 s | Above average · the online median | 50% of people |
| 290 ms | 0.29 s | Average | 43% of people |
| 300 ms | 0.30 s | Average | 39% of people |
| 320 ms | 0.32 s | Average | 30% of people |
| 350 ms | 0.35 s | Below average | 20% of people |
| 400 ms | 0.40 s | Below average | 9% of people |
| 450 ms | 0.45 s | Take another go | 5% of people |
| 500 ms | 0.50 s | Take another go | 2% of people |
| 600 ms | 0.60 s | Take another go | 0.8% of people |
Reaction time in seconds, not milliseconds
Some tests, school worksheets and driving materials report reaction time in seconds, which makes the numbers look deceptively small. The conversion is simply 1 second = 1,000 milliseconds, so move the decimal point three places: 0.25 s is 250 ms, 0.3 s is 300 ms (about average) and 0.2 s is 200 ms (genuinely fast). If you see anything like 0.1 s, treat it with suspicion: 100 ms is the practical floor of a real human reaction, and below it you anticipated rather than reacted.
Watch out for one more mix-up. Driving guides often quote a "reaction time" of around 1.5 seconds, which sounds ten times slower than everything on this page. It is measuring something different: perceiving a hazard, deciding, and moving your foot to the brake, not a simple click. Both are covered on the driving reaction time test.
Is 200, 250 or 300 ms good? The common numbers
These three come up the most, so here they are directly. 200 ms is fast, quicker than roughly nine in ten people and into trained-gamer territory. 250 ms is a touch above the online average, so a little quicker than most. 300 ms is around average-to-slightly-slow online, and it is usually a tired moment, a trackpad, or an older screen rather than your actual reflexes. The checker above will place any number for you, not just these three.
Good depends on how you measured it
One number can be "good" or "average" depending purely on the equipment. A browser test adds 10 to 50 ms of display and input lag on top of your true reaction, so the same person reads slower online than in a lab. That is why our main reaction time test measures your display and shows a device-lag-corrected time next to the raw one, and why a bare number without that context can mislead you. The honest details are on the methodology page.
Good for your age
Age shifts the whole picture. Reaction time is quickest in the early twenties and drifts slower each decade after, so a "good" score at 55 is not the same as at 22. If you want your number read against your own age group instead of everyone, try the reaction age test, and the average reaction time by age page has the full table.
Can I make it better?
A bit. Most people can shave 10 to 20% off with sleep, sensible caffeine timing and regular practice, then they hit a wall set by biology near the 100 ms floor. The evidence-based version is in our guide to improving your reaction time. And if you just want to see where you stand against everyone, the rankings break it into tiers from average to elite.
