Mouse Scroll Test

The Mouse Scroll Test is an essential online utility for diagnosing and benchmarking your mouse wheel performance. Whether you're a competitive gamer utilizing 'infinite scroll' for bunny hopping, or a professional navigating massive documents, a reliable scroll wheel is paramount.

To begin the test, simply place your cursor within the testing area and start scrolling up or down. The tool instantly captures every micro-movement of your wheel, displaying your real-time scrolling speed in pixels per second.

One of the most common hardware failures in modern mice is a degraded rotary encoder. This manifests as 'scroll jumping', where scrolling down occasionally registers an 'up' input, causing the page to jitter violently. Our tool allows you to isolate and verify this frustrating hardware issue.

For users with free-spinning wheels, the Mouse Scroll Test acts as a high-score benchmark. You can unlock the wheel, give it a massive spin, and watch the speedometer track your maximum pixels per second.

The test accommodates all input methods that trigger wheel events, including traditional notched scroll wheels, smooth-scrolling trackpads, and horizontal scroll wheels found on productivity mice like the MX Master.

Our tool is entirely client-side. The rapid calculations required to track thousands of pixels per second happen directly in your browser without any network latency, ensuring perfectly accurate readouts.

We've designed the interface to be visually clear. The dynamic speedometer and direction indicators give you instant, satisfying feedback on your scrolling inputs, making hardware diagnosis a breeze.
