Mouse Button Test

Check left, right, middle, back, and forward mouse buttons with live counters and button state feedback.

Mouse Button Test helps mouse users testing clicks, buttons, scrolling, reaction speed, DPI movement, and switch behavior. It focuses on click timing, button state, scroll behavior, movement or drag stability and runs directly in the browser.

How to use Mouse Button Test

  1. Open Mouse Button Test on the same browser and device you want to diagnose.
  2. Most mouse tests use pointer and button events; DPI estimation may use pointer lock for raw movement capture.
  3. Run the visible mouse button test controls and watch the live result area update before judging the hardware.
  4. Repeat the test once or twice, then compare related InputLab tools if the mouse behavior looks inconsistent.

How to read the result

Mouse Button Test is most useful when you read the result as a practical browser diagnostic. Browser event timing, operating-system pointer settings, polling rate, and repeated runs all affect the final reading. A repeated pattern across multiple runs is more meaningful than one isolated spike, missed event, or visual artifact.

Privacy and permissions

Most mouse tests use pointer and button events; DPI estimation may use pointer lock for raw movement capture. Tests are designed to run locally in the browser, with permissions controlled by the browser.
