Scroll Speed Test
Scroll the test area for ten seconds to measure the distance covered.
Scroll the marked area
Scroll inside the panel for ten seconds. As you approach the bottom, the test adds more track automatically. The result uses the greatest distance reached in CSS pixels, so it varies with browser scaling and input settings.
Tool guide
About Scroll Speed Test
Scroll through a marked browser area for ten seconds and review the maximum distance and average CSS-pixel rate. The result depends on input hardware, browser zoom, and the track length added during the round.
How to use this tool
- 1Start the timed test and scroll inside the marked panel.
- 2Continue toward the bottom; the panel extends the track as you approach its end.
- 3Read the distance and average rate when the ten-second round finishes.
How the tool works
The page measures the greatest scroll position reached in CSS pixels during a ten-second run. As the user nears the end, it adds more content so the track can continue growing. Average rate is distance divided by the test duration.
Worked real-world example
Covering 2,000 CSS pixels in ten seconds gives an average of 200 CSS pixels per second.
Common scenarios and use cases
Compare scroll behavior or test wheel and touchpad input in a repeatable short activity.
Important details and limitations
CSS-pixel distance is not physical distance and changes with zoom and input settings. Trackpad momentum, wheel steps, page focus, and browser behavior affect the result; it is not a device polling benchmark.
Check the output unit as well as the number. If the result will be reused in another calculation, retain full precision where possible and round only at the end. For measurements governed by a technical specification, use the standard and tolerance required by that document.
Frequently asked questions
Why does the test area grow?
It adds track near the end so scrolling can continue.
Is the distance measured in inches?
No, the result is in browser CSS pixels.
Can I compare a wheel and trackpad?
Yes as a rough test, but their input behavior differs.
