Double Click Test: Detect Mouse Bounce and Ghost Clicks
A single click that quietly registers as two is one of the most frustrating mouse problems to diagnose, because it often looks like a software glitch rather than a hardware one. This double click test isolates exactly that issue — click normally, and the tool flags any click that bounces into an unintended second click.
Every click is logged with its interval in milliseconds, so you can see your fastest, slowest, and average timing, along with a running count of total clicks and faulty bounces.
What This Double Click Test Measures
Click normally in the test area using any mouse button. Each click is timed against the one before it, and if two clicks land closer together than your bounce threshold, it's flagged as a faulty bounce rather than a deliberate double-click.
The stats panel tracks total clicks, faulty bounces, and your overall bounce rate as a percentage, while the session stats show your fastest, slowest, and average interval between clicks. The recent click intervals table logs each click individually, so you can see exactly which ones triggered a bounce.
Understanding the Bounce Threshold
The bounce threshold is the minimum time, in milliseconds, that two clicks need to be apart to count as separate, intentional clicks. Anything faster than that threshold is treated as a bounce rather than a real double-click.
A lower threshold makes the test more sensitive and can catch subtler bounce issues, while a higher threshold is more forgiving of naturally fast clicking. If you're not sure where to start, the default setting is a reasonable baseline — you can adjust it up or down depending on how fast you click normally.
What Causes Mouse Bounce
Mouse bounce, sometimes called switch bounce, happens when a mechanical switch's internal contacts don't close cleanly on the first touch. Instead of one clean signal, the switch briefly registers multiple rapid signals before settling — and if that happens fast enough, it can look like two full clicks instead of one. This overview of switch bounce explains the underlying electrical behavior in more detail.
This is most common as a switch wears out over time, though it can occasionally appear on a brand-new mouse with a manufacturing defect.
If your bounce rate is consistently above zero across many clicks, it's a meaningful signal — occasional single flagged clicks can sometimes just be genuinely fast intentional double-clicks landing close to your threshold.
Reading Your Results
A bounce rate near 0% across a reasonable number of clicks suggests your mouse switches are in good shape. A bounce rate that climbs the longer you click, or that shows up consistently on one specific button, points toward a wearing switch on that button specifically.
The recent click intervals table is useful for spotting patterns — if faulty bounces cluster around a particular time gap, that gap is likely close to your mouse's actual bounce window.
Exporting Your Data
The Export CSV option lets you save your click session, including intervals and bounce flags, so you can compare results over time or across different mice. This is useful if you're trying to confirm whether a mouse is getting worse gradually, or if you want to compare a new mouse against an older one before deciding whether to replace it.
Troubleshooting a High Bounce Rate
Bounces Happen on Every Button
If every button shows a similar bounce rate, the issue may be more general — worn internal components, a driver issue, or in rare cases a software conflict rather than one specific switch failing.
Bounces Only Happen on One Button
This points more directly to that specific switch wearing out. Cross-check your findings against the mouse tester to confirm the same button shows inconsistent behavior there too.
Results Vary a Lot Between Sessions
Some variation is expected, since clicking speed naturally changes with fatigue. Run a few separate sessions and look at the overall trend rather than a single result.
Frequently Asked Questions
What's the difference between this and a CPS test?
A CPS test measures how fast you can click. This tool measures whether a single click is unintentionally registering as two. You can check click speed separately with the CPS test.
What bounce threshold should I use?
Start with the default setting. If you're a naturally fast clicker and see false positives, try raising it slightly. If you suspect subtle bounce issues, try lowering it.
Does a bounce always mean my mouse is broken?
Not necessarily one bounce, but a consistent, repeatable bounce rate on the same button is a strong sign of a wearing switch.
Can I test a trackpad or other pointing device?
Yes, as long as the device registers standard click events, it can be tested the same way as a physical mouse.
Do I need to install anything to run this test?
No installation is required. The test runs directly in your browser and logs clicks in real time.
Check Your Mouse Hardware Too
If your bounce results look off, it's worth running the full mouse tester to check buttons, scroll, and drag response, or the CPS test to see if a worn switch is also inflating your click speed. You can also check other parts of your setup with the keyboard test, webcam test, and microphone test.
