Mouse Acceleration Test - Detect & Measure Pointer Speed

Move the same distance slowly and quickly to estimate mouse acceleration from the difference in movement.

Mouse Acceleration Test (Pointer Acceleration Check)

Just move your mouse to display speed (px/s) and acceleration (px/s²) in real time. (browser estimate)

Speed Graph (px/s)

SpeedX-axis: Time (sec)

* The X-axis advances at a fixed rate, so it progresses at the same pace whether the mouse is moving or still.

Acceleration Graph (px/s²)

Acceleration (+ = speeding up / - = slowing down)X-axis: Time (sec)

* Acceleration is displayed above and below center (0). Sudden acceleration or abrupt stops are easy to spot.

About Hold Display

Current speed (px/s) and acceleration (px/s²) use a "hold display" for better readability.
When you move the mouse quickly, browser measurements tend to fluctuate rapidly, making it hard to tell what the current speed actually is. This page updates immediately when values rise, but waits 250ms before following when values drop, so you can confirm peaks (max speed and max acceleration) without losing sight of them.

* Hold display is a visual presentation feature only. The internal sampling continues at high frequency, and peaks from fast movements are reliably captured and displayed.

Note (Regarding Browser Measurement)

This tool estimates speed and acceleration based on cursor movement (px) obtained by the browser. Results are affected by OS mouse acceleration settings, pointer speed, DPI, and display scaling, so this test is better suited for comparison within the same environment (before/after) rather than absolute accuracy. Use it as a mouse acceleration checker, mouse acceleration off verification, or mouse speed test to compare before and after changing settings.
