Mouse Test Online

To test mouse polling rate online, move your mouse continuously in quick, steady circles inside the Polling Rate testing zone on our Mouse Tester. The tool captures native browser pointermove hardware interrupts and calculates frequency in Hertz (Hz) and interval timing in milliseconds (ms). Standard office mice report at 125Hz (8ms), gaming mice at 1000Hz (1ms), and esports mice up to 4000Hz-8000Hz (0.25ms-0.125ms).

A mouse double click occurs when a mechanical micro-switch (such as Omron, Kailh, or Huano) suffers from contact leaf oxidization, spring fatigue, or electrical bounce (chatter). When pressed once, the switch vibrates and sends two rapid actuation signals below the debounce threshold. To diagnose it, use our Double Click Detection module. If chatter is detected, you can: 1. Clean the switch with compressed air or electrical contact cleaner, 2. Increase the debounce delay in your mouse driver software (e.g. 8ms-12ms), or 3. Replace the switch with optical switches that are immune to double-clicking.

For everyday desktop computer tasks, a normal clicking speed is between 5 and 7 CPS. For gaming, competitive players use specialized techniques:

• Regular Clicking: 6 - 8 CPS
• Jitter Clicking: 10 - 14 CPS (rapid arm muscle tremors)
• Butterfly Clicking: 15 - 25 CPS (alternating two fingers on one mouse button)
• Drag Clicking: 20 - 30+ CPS (dragging friction across matte surface)

Our online CPS test measures clicks within 5, 10, or 30-second windows with sub-millisecond precision.

To test mouse DPI (Dots Per Inch) accuracy, measure a physical distance on your mouse pad (such as 2 inches or 5 cm) using a physical ruler. Move your mouse exactly across that physical line while tracking the pixel displacement registered on screen. Dividing the horizontal pixels traveled by the inches moved gives your effective DPI. If the calculated DPI significantly differs from your mouse setting, check that Windows 'Enhance pointer precision' (pointer acceleration) is disabled.

If scrolling down causes your page to intermittently stutter or jump upwards, the mechanical rotary encoder inside your mouse wheel is contaminated with dust, lint, or dried grease. To test it, open our Scroll Glitch Detector and spin the wheel rapidly in one direction. Any reverse directional events will be highlighted in red. You can fix this by blowing compressed air directly into the wheel axle or replacing the 9mm/11mm wheel encoder.

Angle snapping (prediction) is an algorithm in some office mouse sensors that artificially straightens diagonal movements into straight horizontal or vertical lines. Sensor smoothing averages recent positional coordinates to reduce cursor jitter at very high DPI levels, but adds 1-4ms of input latency. For competitive gaming and precise digital art, both angle snapping and smoothing should be turned off in mouse software.

Open this page and use the mouse: click each button and turn the wheel. Every part lights up in the row above as soon as its signal arrives, so anything that stays grey is not reaching the browser. For the things you cannot see by looking — double clicks, polling rate, DPI, click speed, scrolling and sensor drift — pick the matching one of the six checks above. Nothing to install, no account.

The switch under the button has worn out and bounces, sending a second click on its own. It is the most common mouse fault there is, and on most mice the switch can be replaced. The double click test measures the gap between presses and flags anything faster than a finger can move, which is the evidence a warranty claim needs.
