Step 1
Start Testing
Choose one mouse button, set the threshold before starting, and press that same button 25 times. The first press locks the button and threshold so the intervals in the round stay comparable.

What Is a Double Click Test?
A focused browser test that separates observed timing from the troubleshooting decision.

How to Use This Double Click Tester
A quick 30-second workflow. Click, review the gaps, and decide what to do next.
Step 2
Read Your Results
Each row shows the button, the browser-observed gap, and whether it fell below your chosen threshold. A flagged gap is a candidate repeat signal, not proof of a worn switch. Repeat the round in another browser or device before drawing a conclusion, and export the log if needed.
This double click tester compares browser timestamps between consecutive presses of one mouse button. Intervals below the selected threshold are highlighted as suspicious repeat signals. Fast intentional clicking, operating-system settings, drivers, browser event handling, or switch bounce can all affect the result, so use a completed round and a second environment to verify the pattern.

Double Click Test FAQ
Quick answers for common scenarios. Keep scrolling only if you need the details.
What is a double click test?
A double click test records browser-observed intervals between presses and highlights unusually short repeats. It helps you gather evidence before checking settings, drivers, connections, or the mouse switch.
How do I know if my mouse is double clicking?
Complete a 25-press round with one button. Repeated flagged intervals are a reason to retest in another browser, port, or computer; they do not identify the cause by themselves.
What is a normal click interval?
There is no universal normal interval because clicking style and system settings vary. Very short gaps can be suspicious when they recur during deliberate single presses, but one gap alone does not identify the cause.
Can double clicking be fixed without replacing the mouse?
Yes, you can try adjusting system settings, cleaning the switches, or using software fix tools before considering replacement.
Does this test work on Mac / Chrome / Firefox?
Yes, this is a pure browser-based tool compatible with all major operating systems and browsers.
Is this double click test free?
Completely free, no registration required, no installation needed.
How accurate is an online double click test?
The tool uses performance.now() to compare browser event timing. It is useful for spotting repeat patterns, but browser timing alone cannot prove which hardware or software layer caused them.
What threshold should I use for double click detection?
Start with 80 ms as a conservative candidate-signal threshold. If flags recur, repeat the same-button test in another browser, USB port, or computer before troubleshooting hardware.
