Move your mouse inside this area
Trace a straight line from one side to the other at the selected speed. Use the same start and end points for both runs to see how distance changes.
Pick a run to start and move in a straight line inside the box.

Conclusion
Complete both runs to estimate acceleration.
If acceleration is off, your cursor should travel about the same on-screen distance no matter how fast you move the mouse along the same physical path.
Speed vs. distance
Higher lines mean quicker movements at each point along the path.
Complete a run to see your speed profile plotted over distance.
We calculate distance between pointer events and derive instantaneous speed from the time between those events. Higher total distance at faster speed hints at acceleration from your OS, drivers, or mouse software.
Cursor consistency
Mouse Speed Acceleration Test
Run this test twice: once with slow, steady movement and once with a quick swipe along the same path. If the fast run produces much more on-screen distance, your operating system or mouse software may be adding acceleration.
How to run the comparison
- Pick a start and end point inside the box, then perform a slow pass across that line.
- Repeat the same path quickly for the fast run, keeping your physical travel distance identical.
- Compare the distances: similar totals mean acceleration is off, larger differences suggest it's on.
Reset and retry if the lines look uneven or if you stray from the intended path. Consistent runs give the clearest read on acceleration.
