Mouse DPI (dots per inch) affects cursor speed—higher DPI means the cursor travels further with less physical movement. While our tool doesn't measure DPI directly, it helps you verify that your mouse is working correctly before fine-tuning your settings.
Why DPI Matters
DPI determines how far your cursor moves when you move your mouse. Most gaming mice offer adjustable DPI, typically ranging from 400 to 16000+.
- Low DPI (400-800): Better for precision tasks and FPS games
- Medium DPI (1200-2400): Balanced for general use
- High DPI (3200+): Useful for large monitors and fast movements
To check or change your DPI, use your mouse software (e.g., Logitech G Hub, Razer Synapse) or your system settings.
What Our Mouse Tester Can Test
Our free Mouse Tester runs in your browser and verifies:
- Clicks – Left, right, middle, and side buttons register correctly
- Scroll wheel – Up/down scrolling is smooth and consistent
- Button hold – Clicks hold without releasing unexpectedly
- Sensor tracking – Movement is smooth without jitter or jumps
How to Use the Mouse Tester
- Open the Mouse Tester – Navigate to our Mouse Tester page
- Move your mouse – Make sure the cursor moves smoothly in the test area
- Click each button – Verify every click appears in the event log
- Scroll the wheel – Check that scroll direction and count are correct
Tips for Testing
- Use a consistent surface (mouse pad recommended)
- Disable mouse acceleration in your OS settings for more predictable movement
- Test all buttons, including side buttons if your mouse has them
Our tool works in any modern browser and requires no downloads. Try it today to ensure your mouse is performing as expected before adjusting DPI or other settings.
