Scroll Test
Scroll up and down inside the box for 5 seconds — measures your scroll wheel's tick rate.
What counts as a tick
Each distinct wheel event within the 5-second window counts as one tick; your score is ticks per second. It's a simple, honest measure of how fast — and how evenly — your scroll wheel responds.
Frequently asked questions
What does the scroll test measure?
It counts scroll wheel ticks per second and checks the timing between them, giving you a sense of your scroll wheel’s speed and consistency.
Why would my scroll wheel skip or double-count?
A worn or dirty scroll wheel encoder can miss ticks or register extra ones, similar to how a worn mouse button switch double-clicks. This test can help you notice the pattern.
How this test works: everything runs and is timed locally in your browser, and results depend on your device and conditions. Scores are for casual benchmarking and entertainment — not a clinical, medical or diagnostic measurement.
