Mouse & Click Test

Move your cursor onto the pad above and click each button one at a time — left, right, middle (the wheel), and the side buttons if your mouse has them. In this Mouse Click Test every button lights up and gets ticked off the checklist the moment it registers, and scrolling the wheel up and down confirms it too. If a button never lights up, that switch may be worn or the mouse may need its driver software.

The fastest check is to run the Mouse Click Test above and click each button while moving the cursor around. A healthy mouse lights up every zone you press, ticks off the checklist, and shows steady live X and Y coordinates with no sudden jumps. If a button stays dark or the pointer jitters, that input has a problem worth investigating.

Press straight down on the scroll wheel, not just spin it — the wheel and a clickable middle button are separate functions, and one can fail while the other works. In the Mouse Click Test above the middle button lights up and ticks off the checklist when it registers a real press. This is worth checking, since a dead middle click breaks opening links in new tabs and panning in many apps.

Hover over the test pad and roll the wheel up and then down. The Mouse Click Test shows the live scroll direction and delta and marks both up and down on the checklist, so you can confirm scrolling is detected smoothly in each direction. Erratic or skipped readings often point to a dirty or worn wheel encoder.

Click the back and forward thumb buttons on the side of your mouse and watch the Mouse Click Test diagram — each one should flash and tick off the checklist when it fires. These are marked optional because many mice route side buttons through driver software rather than sending them to the browser, so a missing tick is not always a fault. If they work in their own software but not here, that routing is usually the reason.

First run the Mouse Click Test here to confirm the button never registers, then rule out software by updating the mouse driver, restarting, and trying a different USB port or computer. A button that fails everywhere usually has a worn microswitch, which a switch replacement or a new mouse will fix. Cleaning around a sticky button with a little rubbing alcohol can also revive presses that feel mushy or intermittent.

Double-click chatter is when a single, deliberate press registers as two clicks because the button microswitch is wearing out and bouncing the signal. Run the Mouse Click Test and click slowly and deliberately — if the double-click readout flags a press you only meant once, the switch is likely degrading. A too-fast double-click speed setting can mimic it, so adjust that slider first before assuming the hardware is bad.

For accuracy, use the Mouse Click Test above and confirm every press is acknowledged once and only once while the cursor coordinates stay steady between clicks. To measure raw clicks per second instead, a dedicated CPS or speed test is the better fit, since this tool focuses on whether each button and the wheel register cleanly. Together they tell you both that your mouse works and how fast and reliably it responds.

Yes. The Mouse Click Test handles the left, right and middle buttons, the scroll wheel, and the extra back and forward side buttons that gaming mice rely on. Testing before a session is a quick way to catch a doubled or dropped click that could cost you a round. For programmable buttons mapped through gaming software, also confirm them in that software, since they may not reach the browser.

Yes, the Mouse Click Test is completely free, runs in your browser with no download or sign-up, and keeps all data on your device. Before buying a used mouse, spend a minute here clicking every button, pressing the wheel, scrolling both ways, and moving the cursor to watch for jitter. Worn switches, a dead button, or a flaky scroll wheel will show up right away — before any money changes hands.
