Measured on press, not release
Timing starts on the animation frame the screen changes and stops the instant you press, using high-resolution browser timestamps. Releasing a mouse button can add tens of milliseconds, so we ignore it.

Why it’s better
A more accurate reaction time test
Many reaction tests time the click on release, only test one kind of reaction, and give you a single number with no context. This one is built to measure properly and explain what your score means.
Visual, audio and choice modes
Test simple visual reactions, react to a beep with your eyes closed, or take a two-choice test where you must hit the correct side. Each mode has its own records.
More than one number
See your average, best, median and consistency, a rating from Elite to Slow, where you sit on a speed scale, and a chart of every attempt in the round.
Guess-proof
The wait before green is random between 1.5 and 5 seconds. Clicking early, or faster than a human can physically react, does not count, so lucky guesses cannot inflate your score.
Personal records
Your best average, best single reaction and a trend of your last 10 rounds are saved on your device, so you can see whether practice, sleep or a new mouse is making you faster.
Private and accessible
No account and no data sent anywhere. Works with mouse, touch or keyboard, with clear labels and announcements for screen readers.

How it works
How to take the reaction time test
One round takes under a minute. Sit comfortably with your finger resting on the button.
Choose a mode
Visual for the classic test, Audio to react to a beep, or Choice to hit the side that lights up. Pick 3, 5 or 10 attempts.
Start the round
Click, tap or press Space. The screen turns red. Keep your eyes on it and wait without clicking.
React to the signal
The moment it turns green, or the beep plays, press as fast as you can. Too early and the attempt is repeated.
Read your results
After the last attempt you get your average, rating, median, consistency and a chart. Play again to beat your record.
Benchmarks
What is a good reaction time?
For a simple visual test on a normal computer, most people average somewhere between 200 and 300 milliseconds. Large online tests commonly report a typical result of roughly 250 to 280 ms. Reactions to sound are usually a little faster, and choice reactions are slower because your brain has to decide as well as react. The ratings below are guide values for online tests on a typical 60 Hz screen.
| Rating | Visual | Audio | Choice |
|---|---|---|---|
| Elite | Under 180 ms | Under 150 ms | Under 260 ms |
| Excellent | 180 to 214 ms | 150 to 184 ms | 260 to 294 ms |
| Great | 215 to 249 ms | 185 to 219 ms | 295 to 329 ms |
| Average | 250 to 289 ms | 220 to 259 ms | 330 to 369 ms |
| Below average | 290 to 349 ms | 260 to 319 ms | 370 to 429 ms |
| Slow | 350 ms or more | 320 ms or more | 430 ms or more |
Understand your score
Why your reaction time changes
Your score is your own reaction plus the delay of your equipment. Knowing both helps you compare results fairly.
Device and setup
- Screen refresh rate. A 60 Hz display updates every 16.7 ms, so the green can appear up to one frame later. 144 Hz and faster monitors cut this delay.
- Display lag. TVs and some monitors add processing delay. Use Game mode if your screen has one.
- Mouse and keyboard. Wireless and low polling-rate devices can add a few milliseconds. Our mouse tester shows your polling rate.
- Phones and tablets. Touchscreens usually add more delay than a mouse, so mobile scores are often slower.
You
- Sleep and fatigue are the biggest everyday factors. Tired reactions are slower and far less consistent.
- Attention. Distractions, notifications and background noise all slow you down.
- Warm-up. Your first few attempts are usually slower. Scores improve after a round or two.
- Age. Reaction time is typically fastest in your twenties and slows gradually with age, though regular practice and exercise help.
Train smarter
How to improve your reaction time
Reaction speed responds well to good habits and focused practice.
Sleep and exercise
Consistent sleep and regular aerobic exercise support faster, steadier reactions more than any trick or supplement.
Focus on the signal
Relax your hand, rest a finger on the button and watch the colour itself instead of trying to predict when it will change.
Practise regularly
Short daily sessions, fast-paced games and sports drills all train quick responses. Track your 10-round average to see real progress.
Upgrade the weakest link
A high refresh rate monitor and a wired mouse remove hardware delay. Check your refresh rate with our screen resolution checker.
Athletes and drivers
Sprinters, goalkeepers and racing drivers use reaction drills to sharpen starts. Everyday drivers benefit from staying rested and undistracted.
Classroom experiments
Compare visual and audio reactions, before and after exercise, or morning versus evening. Copy each result to build a simple data set.
FAQ
Reaction time test: frequently asked questions
What is the average human reaction time?
For a simple visual reaction on a computer, most adults average between about 200 and 300 milliseconds, and large online tests commonly report a typical result of roughly 250 to 280 ms. Laboratory equipment with no screen or mouse delay usually measures somewhat faster times.
What is a good reaction time?
In this visual test, under 250 ms is better than typical, under 215 ms is excellent and under 180 ms is elite. For the audio test subtract about 30 ms, and for the choice test add about 80 ms, because choosing a side takes extra thinking time.
Is reaction to sound faster than reaction to sight?
Usually, yes. Sound reaches the brain and is processed slightly faster than vision, so most people react to a beep a few tens of milliseconds faster. Try the Audio mode with your eyes closed and compare it with your Visual score.
What is choice reaction time?
Choice reaction time is how quickly you respond when there is more than one possible signal and each needs a different response. In Choice mode either the left or right side lights up and you must press that side. It is slower than simple reaction time and closer to real situations like sports and driving.
Why is my reaction time slower on my phone?
Touchscreens take time to detect and process a tap, and many phone screens refresh at 60 Hz. Together this can add noticeable delay compared with a desktop monitor and a wired mouse. Compare scores on the same device to track real improvement.
Does monitor refresh rate affect reaction time tests?
Yes. The colour change can only appear on the next screen refresh, which is up to 16.7 ms later at 60 Hz but under 7 ms at 144 Hz. High refresh monitors, low-latency modes and wired devices all lower your measured time.
How accurate is this reaction time test?
The test uses the browser’s high-resolution timer, starts timing on the frame the colour changes and stops on press rather than release. The remaining error comes from your screen, input device and operating system, typically a few to a few tens of milliseconds. Treat it as an excellent benchmark, not a medical measurement.
Can you improve your reaction time?
Yes, within limits. Good sleep, regular exercise, practice and a focused, relaxed technique can all make your reactions faster and more consistent. Faster hardware lowers the delay your equipment adds.
