Measured in double clicks per second ยท higher is better
Double Click Test
Two things at once: is your mouse chattering, and how fast can you double click on purpose.
Before you start
The median on mouse is 3.10 DPS. Run the test and we will place you against it.
Compared against
Chatter detection needs a physical switch. On a trackpad the driver already filters short intervals, so the check will not fire.

Curve is a fitted baseline plus 0 first attempts recorded here. The baseline is a curve, not a sample: no part of it is a real person. Baseline is an estimate: centred on roughly half the sustained single click rate, which is what a double click costs. No published dataset was found for it. Per-device offsets are extrapolated, not measured. The baseline is dropped once a device class holds 5,000 real first attempts. See the full distribution.

Understanding your score
| Band | DPS | What it means |
|---|---|---|
| Very fast | 4.50 and above | Top few percent. |
| Fast | 3.60 to 4.49 | Above average. |
| Average | 2.50 to 3.59 | Most people land here. |
| Below average | 1.50 to 2.49 | Often a heavy switch rather than a slow hand. |
| Slow | 1.49 and below | Check whether clicks are being dropped. |
The chatter check
Switch chatter is the failure where one physical press produces two electrical signals. It is what people mean when they say their mouse is double clicking by itself, and it is the most common way a mouse dies.
Every click on this page is logged with the gap in milliseconds since the previous one. A human cannot produce two intentional clicks less than about 40 milliseconds apart, so any gap below that threshold is flagged. If flagged gaps appear while you are clicking once per second, the switch is failing.
Chatter is progressive. It starts as an occasional flagged event and becomes constant over weeks or months. It is a mechanical fault in the switch and it does not get better.
The speed measurement
The second number is how many deliberate double clicks you can complete per second. Around 3 per second is typical, which means each double click takes roughly 320 milliseconds including the pause between pairs.
This is a different skill from raw click speed. A double click requires two clicks close enough together for the system to pair them and then a deliberate gap before the next pair, so it rewards rhythm control rather than pure rate.
If your mouse is chattering
Some mouse software includes a debounce time setting. Raising it to 8 or 12 milliseconds masks mild chatter by ignoring signals that arrive too soon after the last one. It buys time, it does not fix the switch, and it adds a small amount of input latency.
A failing switch can be replaced if you are comfortable soldering. Most mice use a standard Omron or Kailh switch that costs very little. The alternative is a new mouse.
Cleaning helps only when the cause is debris rather than a worn contact, which is the less common case.
The system double click window
Your operating system decides what counts as a double click, not the application. Two clicks are paired only if they arrive within a set window, typically 400 to 500 milliseconds by default, and only if the pointer barely moved between them.
Shortening that window in system settings makes deliberate double clicks harder to land and is a common cause of people believing their mouse has failed. Lengthening it makes accidental pairs more likely, which looks exactly like chatter without any hardware fault involved.
This page counts raw click events and their intervals rather than relying on the system pairing, so it measures the same thing regardless of how your window is configured. That is what makes the chatter check trustworthy across machines.
Questions
- Could a system setting be causing what looks like chatter?
- Yes. A long double click window makes two intentional clicks pair when you did not want them to. This page reads raw intervals rather than system pairing, so if it flags gaps under 40 milliseconds the cause is the switch, not a setting.
- How do I know if my mouse is double clicking on its own?
- Click once, slowly and deliberately, about ten times. If the counter increments by two on any of them, or if the log flags a gap under 40 milliseconds, the switch is chattering.
- Can switch chatter be fixed?
- Raising the debounce time in your mouse software masks it. Replacing the switch fixes it. Cleaning occasionally helps if the cause is debris. Nothing in the operating system will repair a worn contact.
- What is a normal double click speed?
- Around 3 double clicks per second. Above 4.5 is fast. This is a rhythm task rather than a raw speed task, so it does not track click speed closely.
- Why does the system double click interval matter?
- Your operating system only pairs two clicks into a double click if they arrive within a set window, typically 400 to 500 milliseconds. That window is a system setting, and lowering it makes deliberate double clicks harder to register.
