Frequently asked questions
What does the scroll test measure?
It counts wheel events in each direction over a fixed period and converts the total into scrolls per second. Free-spin wheels generate far more events than notched wheels.
How do I check for a faulty scroll wheel?
Scroll slowly in one direction only. If the counter registers events in the opposite direction, or stalls while the wheel keeps turning, the encoder is likely dirty or worn.
Why is my touchpad score so high?
Touchpads emit smooth high frequency scroll events rather than discrete notches, so counts are much higher than a physical wheel. Compare wheel with wheel and touchpad with touchpad.

About this scroll test
This is the 5 seconds version of our scroll test, locked to a single duration so every score on this page is directly comparable. The scroll test counts individual mouse wheel events, which makes it useful for two things: competing on wheel speed, and diagnosing hardware. A healthy wheel produces a steady stream of events in one direction; a worn encoder produces phantom events in the opposite direction or skips entirely.
