Mouse Test Online Test Your Mouse Free Click · Scroll · DPI · Buttons · CPS · Speed

Yes — 100% free with no hidden fees, no subscription, no premium tier, and no registration required. Every feature is completely free: click test with per-button counts, 10-second CPS speed test with rating, scroll wheel tick counter with up/down direction tracking, double-click speed measurement in milliseconds with pass/fail verdict, canvas click trail with left/right/middle color coding, live movement tracker with speed and distance, sensitivity delta X/Y measurement with smoothness rating, all-buttons panel including side buttons 4 and 5, live Mouse Health Report with 6 metrics, and the realistic interactive 3D mouse SVG that highlights every button in real time.

Click the Scroll Test tab inside the Mouse Test Suite. Scroll your mouse wheel up and down inside the box. Every individual wheel notch is counted and shown as Up Ticks and Down Ticks separately — the Last Direction indicator also shows which way you last scrolled. A healthy scroll wheel produces exactly one tick per physical notch. If you see two ticks per notch, your scroll encoder is dirty and needs cleaning with compressed air. If ticks are missing, the encoder is worn and the mouse may need replacing.

CPS stands for Clicks Per Second — the number of times you can click a mouse button in one second. Use the Click Speed Test section and click Start CPS Test, then click as fast as possible in the zone for 10 seconds. The tool counts every click and calculates your average CPS over the full 10 seconds. Average users score 4–7 CPS. Competitive gamers regularly achieve 8–14 CPS. The jitter click technique can exceed 14 CPS but stresses the micro-switch hardware. Your best CPS and average CPS are stored and displayed separately after the test completes.

No downloads, no installations, no browser extensions, no Flash, no plugins, and no account creation of any kind are required. This is a fully browser-based online mouse test that runs entirely in JavaScript using standard browser mouse event APIs — MouseEvent, WheelEvent, and PointerEvent — built into every modern browser. Open the page in Chrome, Edge, Firefox, Safari, or Opera and the complete 7-tab mouse test suite is available instantly, completely free, with no sign-up and no registration of any kind.

Unintended double-clicks are caused by a worn micro-switch that electrically bounces after each press — generating two signals from one physical click. This is called "click chatter" or "micro-switch bounce." Use the Double Click tab to confirm: if two events appear when you click once, the micro-switch has failed. A temporary fix is to slow your OS double-click threshold (Windows Control Panel → Mouse → Buttons → Double-click speed → Slow). The permanent fix requires replacing the micro-switch (a solder repair) or buying a replacement mouse.

Yes. This free online mouse test works with any input device your computer recognizes — wired USB, wireless 2.4GHz with dongle, Bluetooth, gaming mice, office mice, trackballs, and laptop touchpads. Connect or pair your wireless mouse before opening the page and it works identically to a wired mouse. The Movement and Sensitivity tabs are particularly useful for comparing whether wireless latency or Bluetooth polling rate is affecting responsiveness compared to a wired connection on the same computer.

DPI (dots per inch) — also called CPI (counts per inch) — determines how many pixels the cursor moves per inch of physical mouse movement. Higher DPI settings move the cursor further with less physical movement. The Sensitivity tab in this tool tracks raw delta X and delta Y movement values per event using the browser's MouseEvent.movementX and movementY properties. At higher DPI settings these values are larger for the same physical movement. Use it to compare sensitivity between DPI settings or confirm that pressing the DPI button on a gaming mouse is changing sensitivity as expected.

Navigate to the All Buttons tab in the Test Suite. This panel detects button 0 (left), button 1 (middle/scroll click), button 2 (right), button 3 (side back / button 4), and button 4 (side forward / button 5) which correspond to side buttons on gaming mice. Press each button to confirm it registers. Note that some browsers intercept navigation buttons before they reach the test — in that case, install the manufacturer's software (Logitech G Hub, Razer Synapse, SteelSeries GG) to remap side buttons and confirm registration in your apps.

The Click Trail test draws a colored circle at the exact coordinate of every mouse click on an HTML5 canvas — left clicks in orange, right clicks in blue, middle clicks in green. This visualizes click distribution and precision over time. For regular users it shows click accuracy patterns. For gamers it reveals whether clicks are landing consistently in intended areas or drifting due to arm fatigue or mouse weight. It also confirms that coordinate tracking is accurate across the full surface area without dead zones or position offset errors anywhere on the canvas.

Most free online mouse tests offer only a basic click counter or simple left/right button check. This tool provides: a realistic 3D SVG mouse that animates every button (left, right, scroll wheel ridges, middle click, both side buttons, and LED indicator) on each press; a 6-point live Mouse Health Report; a 7-tab test suite (Click Test, Double-Click, Scroll Test, Click Trail canvas, Movement Tracker, All Buttons, Sensitivity); a 10-second CPS speed test with best/average tracking and rating; double-click speed measurement in milliseconds with pass/fail verdict; canvas click trail with 3-color button coding; movement trail visualization with speed and total distance; delta X/Y sensitivity with smoothness rating; button health check panel; double-click speed analysis panel; fix guide for 8 common problems; and 10 detailed FAQs — all completely free, no registration, no download.
