Distance counts only while the timer runs — up or down, every pixel of travel counts.
Start here — scroll
How fast can you scroll? Scroll the tall track for 10 seconds — mouse wheel, trackpad, or touch — and get your average pixels per second, total distance, and peak one-second burst. Best speed saved on your device.

The scroll test at practicalwebtools.com/other/scroll-test measures how fast you can scroll: scroll the tall track for 10 seconds with your mouse wheel, trackpad, or touchscreen, and it reports average pixels per second, total distance, and your peak one-second burst on a rating scale. Your best speed is saved on your device, and everything runs in this browser tab.
Pick "Start 10-second test" — the track returns to the top and the timer starts
Scroll the track with your wheel, trackpad, or finger — travel counts in both directions
Watch the live pixel count and px/s readout until the 10 seconds run out
Read your average speed, peak one-second burst, rating, and device best
The track is an 8,000-pixel-tall scrollable box. Every scroll event contributes the absolute change in scroll position as distance, and speed is that distance divided by the 10-second test window. Direction is irrelevant — scrolling back up counts the same as scrolling down, because both are travel. The page reads native scroll events on the track, which is why wheel, trackpad, and touch all work without any special handling.
Alongside your average, the test slides a one-second window across the whole run and reports the window with the most pixels traveled in it. Most people burst far faster than they sustain — a hard trackpad flick can post a huge peak while the average stays modest — so the two numbers tell you different things about your scrolling.
Yes. Anything that scrolls the track — mouse wheel, trackpad, touchscreen, even a stylus — produces the same native scroll events the test reads. On phones the track is 420 px tall, which is enough for a finger-drag test, though a flick that hits the top or bottom boundary stops counting until you travel again.
No. The track is an ordinary overflow-scroll box: the test never calls preventDefault on wheel or touch events, and scrolling anywhere else on the page behaves normally. The only touch of styling is overscroll-behavior: contain on the track itself, which stops an accidental fling at its edge from jumping the page underneath — standard browser behavior you can verify in any devtools.
In localStorage on your own device, under a single key. It never leaves the browser — you can watch the Network tab while testing and see no requests. Clearing site data in your browser settings removes it.
It depends heavily on the input device, which is why the rating scale is deliberately broad. A notched mouse wheel typically lands in the hundreds to low thousands of pixels per second; trackpad and touchscreen flicks run far higher. Treat the rating as a per-device benchmark: the useful comparison is your own runs on the same hardware.
