About the Keyboard Test
This keyboard test, also called a keyboard tester, shows a full-size layout on screen and lights each key the moment you press it. Keys you have already tested keep a tint, so any key that never lights up is easy to spot. That is the quickest way to find a dead key, a sticky switch or a key that sends the wrong character.
It also tracks how many keys you are holding at once, and the most you have held at the same time. Hold several keys together and see whether they all register. If some are missed, your keyboard may have limited key rollover, also called ghosting, which matters for fast typing and for games with many simultaneous inputs.
Everything happens in your browser. Nothing you type is stored or sent anywhere, and the page does not need any permission or install.
How the test works
- Click the keyboard area so it has focus. You will see a highlight when it is listening.
- Press keys one by one. Each key lights up while held and stays tinted afterwards.
- To test rollover, hold as many keys as you can at once and watch the "most at once" counter.
- Press Finish to see how many keys you covered. Reset clears everything for a fresh run.
Levels
Your score maps to one of 8 levels. These ranges are guides, not official standards.
| Level | Name | Score |
|---|---|---|
| 1 | Just started | 0+ keys |
| 2 | Getting going | 10+ keys |
| 3 | Warming up | 25+ keys |
| 4 | Halfway there | 45+ keys |
| 5 | Thorough | 65+ keys |
| 6 | Almost done | 85+ keys |
| 7 | Full sweep | 98+ keys |
| 8 | Every key | 104+ keys |
Tips to improve
- Laptops and compact keyboards have fewer keys than the 104-key layout shown here, so a full sweep is not possible on them. Test the keys you actually have.
- Some keys, such as Fn, are handled by the keyboard itself and never reach the browser. They will not light up even when they work.
- Browsers and operating systems may swallow a few shortcuts, such as Alt+Tab or the Windows key. Treat those as untestable here.
- If a key is slow to light up or fires twice, clean it with compressed air and test again before assuming the switch has failed.
Frequently asked questions
Is this a keyboard tester or a typing test?
It is a keyboard tester. It checks whether each key registers and how many keys it can read at once. It does not measure typing speed. If you want to see how fast you can press keys, try the spacebar counter or the other tests on this site.
How do I know if a key is broken?
Press it several times. If it never lights up on the layout, the key or its switch may be dead, or the key may be remapped. Try it in another app, too, to rule out the browser.
Why do Fn, volume and some other keys not light up?
Many laptop keyboards handle Fn, brightness and volume keys in hardware or the operating system. They never send a key press to the browser, so no web page can see them.
What is ghosting and key rollover?
Ghosting is when pressing several keys at once makes some of them not register, or register as a different key. Rollover is how many keys a keyboard can report at the same time. A higher number is better for gaming and fast typing.
How many keys should I be able to hold at once?
Cheap keyboards may report only two to six, while many gaming keyboards report much more. This test shows what the browser receives, so it is a rough check rather than a lab measurement.
Does this test work on a phone or tablet?
Only if the device has a physical or Bluetooth keyboard connected. A touch keyboard does not send the same events, so most keys will not light up.
Is anything I type recorded?
No. Key presses are used only to light the on-screen keys and are never stored or sent. Because the test blocks the browser's own shortcuts while focused, press Tab or click elsewhere to leave it.
