Mouse Test - Check Clicks, Scroll Wheel & Buttons Online
Test left click, right click, middle button, and scroll wheel. Detect double-click issues and verify all mouse inputs instantly in your browser.
Verify clicks and scrolls
Follow the steps, click left/middle/right, and scroll up/down on the illustration. Once all five actions are detected, your mouse passes.
Get started with your test
- 1Click all buttons
Press left, middle (wheel click), and right. Each card should highlight and count your presses.
- 2Scroll up and down
Hover the illustration, scroll the wheel up once, then down once. Both arrows should light up.
- 3Check your score
Score reaches 100% when all five actions are detected. Use reset to run it again.
- Keep your cursor inside the illustration to capture scroll events.
- Right-click is captured even if the context menu is blocked here.
- Use reset if you want a clean run or to test another mouse.
Interact directly with the mouse illustration. Each action lights up and counts toward your score.
What is a Mouse Test?
A mouse test verifies all your mouse functions are working: left, right, middle button clicks, and scroll wheel movement in both directions. It detects common issues like double-clicking bugs and scroll wheel skipping. Useful for troubleshooting, testing mice before purchase, or diagnosing hardware issues. This browser-based tester runs instantly with no installation required. Use it as a mouse click test, double click test, scroll wheel test, or full mouse button test—all free in your browser with no software needed.
What Each Mouse Test Does
Our mouse tester covers every standard input check in one place.
Mouse Click Test
Verify left click, right click, and middle button independently. Each button lights up on press and resets on release. Confirms all three primary mouse buttons are registering correctly.
Double Click Test
Detect if single clicks are being registered as double-clicks—a common symptom of micro-switch wear. Our test highlights each click event so you can see if extra clicks are appearing unexpectedly.
Scroll Wheel Test
Test scrolling up and down to check for skipping, jumping, or scroll reversal. Identifies worn scroll encoders and debris-related scroll issues before they get worse.
Mouse Button Test
Complete button coverage for all three standard mouse buttons. Side buttons (back/forward) typically require manufacturer software, but left, right, and middle are fully testable here.

How This Online Mouse Test Works
Our mouse tester uses JavaScript event listeners to detect mouse button presses (left, right, middle) and scroll wheel movements. When you click or scroll, the browser fires events that we capture and visualize in real-time. We track each button's state, count clicks, measure scroll direction and speed, and detect potential double-click issues. All processing happens locally in your browser with no data sent to servers.
Accuracy and Limitations
This browser-based test accurately detects standard mouse buttons (left, right, middle) and scroll wheel events. However, there are limitations: Side buttons and extra gaming buttons may not be detected by browsers. DPI and sensor accuracy cannot be tested through web events. Some gaming mice with proprietary drivers may behave differently. For comprehensive mouse diagnostics, manufacturer software may be needed.
How to Interpret Your Results
Click Response
Buttons should light up immediately when pressed and return to normal on release. Delayed or stuck highlights may indicate switch issues or driver problems.
Double-Click Detection
If single clicks register as double-clicks, your mouse likely has switch wear. This is a common issue in older mice and may require repair or replacement.
Scroll Behavior
Scroll should register smoothly in both directions. Skipping, reversing, or erratic behavior indicates encoder issues or debris inside the scroll mechanism.
When to Test Your Mouse
Common situations where an online mouse test is essential.
Gaming & Esports
Unintentional double-clicks and scroll jumps directly affect competitive gaming performance. Verify your mouse is registering inputs correctly before ranked matches.
Testing a Used Mouse
Always test a second-hand mouse before buying. Check all three buttons for correct registration and scroll for smoothness—common wear points on used mice.
Diagnosing Double-Click Issues
Use our click test to confirm whether your mouse has switch wear. Seeing two click events per press confirms the problem and helps you decide between repair, warranty claim, or replacement.
After Driver or Firmware Update
Mouse driver updates occasionally change button behavior or scroll sensitivity. Run a quick test after updates to confirm all inputs are responding as expected.
Mouse Troubleshooting Guide
Common mouse problems and how to diagnose them.
Double-Clicking Issue
Cause: Micro-switch wear or too-short debounce time. Fix: Adjust double-click speed in OS settings, clean the switch with compressed air, update firmware, or replace the micro-switch. Check manufacturer warranty—many brands cover this.
Scroll Wheel Skipping
Cause: Dust or debris in the scroll encoder, or worn encoder wheel. Fix: Blow compressed air around the scroll wheel, reduce scroll speed in OS settings. If persistent, the encoder may need replacement.
Button Not Responding
Cause: Loose USB connection, driver conflict, or faulty switch. Fix: Try a different USB port, unplug and replug, reinstall mouse drivers, or test in another browser. If only one button fails consistently, the switch may need replacement.
Mouse Testing Glossary
Key terms to understand your mouse test results.
- Polling Rate
- How frequently your mouse reports its position to the computer, measured in Hz. A 1000Hz polling rate means the mouse sends 1000 updates per second (every 1ms). Higher polling rates reduce input latency—important for fast-paced gaming.
- Double Click Issue
- When a single click registers as two clicks due to micro-switch wear or misconfigured debounce settings. Common in heavily-used mice. Measurable with a click test that shows per-click events.
- CPS (Clicks Per Second)
- A measure of clicking speed. Average users click 6–8 CPS; competitive gamers often exceed 10–14 CPS. CPS is tracked in dedicated click speed tests, not standard mouse button tests.
- DPI / CPI
- Dots Per Inch (or Counts Per Inch)—a measure of mouse sensor sensitivity. Higher DPI means the cursor moves further per inch of physical mouse movement. Does not affect click or scroll accuracy.
- Debounce Time
- The time window after a click during which additional click signals are ignored to prevent double-click misregistration. Typically 10–30ms. Too short causes double-click issues; too long makes rapid clicks feel unresponsive.

Mouse Care Tips
Keep your mouse performing reliably for longer.
Clean Mouse Feet and Pad Regularly
Dirt and grit on mouse feet or your mousepad increase friction and affect sensor tracking accuracy. Wipe the feet with isopropyl alcohol and clean your mousepad monthly.
Use the Right Mouse Pad
Cloth pads work better with optical sensors; hard pads reduce friction for faster movement. Using an inappropriate surface can cause cursor jitter and affect sensor accuracy.
Update Mouse Firmware
Logitech G Hub, Razer Synapse, SteelSeries GG, and other manufacturer apps provide firmware updates that can fix double-click issues, improve polling rate stability, and add features.
Check Debounce Settings in Driver Software
Some gaming mouse software lets you adjust debounce time. If your mouse double-clicks, try increasing debounce. If rapid clicks aren't registering, reduce it. Finding the right balance improves reliability.
