Touchpad & Trackpad Test.
Move your finger across the pad to draw a live trail that reveals every jump, dead zone and stutter — then check taps, two-finger scroll, multi-touch contacts and pressure. This trackpad test runs entirely in your browser: nothing to install, nothing uploaded, and every result stays on your device.
Move across the pad to start — the trail follows your cursor

Glide, tap, two-finger scroll, and place several fingers at once. The trail fades behind your cursor; cells you never touch stay dark.
Get an accurate reading
- Wipe the pad firstSkin oil and grit are the most common cause of a "jumpy" or dead trackpad. Wipe it with a dry microfibre cloth before you blame the hardware — a smear can register as a phantom contact or block a real one.
- Cover the whole surfaceDrag slowly into all four corners and both edges. The coverage grid only clears a cell once a contact lands on it, so a corner that stays dark after you've deliberately swept it is a genuine dead zone, not an oversight.
- Go slow to see jitterMove at a steady, moderate speed. A clean pad draws one smooth line; a failing one shows the trail hopping sideways, snapping to a spot, or breaking up. Fast flicks hide those glitches — slow, deliberate passes expose them.
- Test on the actual deviceResults reflect the trackpad you're using right now, through this browser and OS. An external mouse, a USB hub, or a remote-desktop session all change what the browser sees, so run it on the laptop you're diagnosing.
How to test your touchpad
- 1Draw across the surface. Rest one finger on the pad and move it around. A fuchsia trail follows your cursor and fades behind it — a smooth, continuous line means clean tracking; hops, gaps or snaps mean trouble.
- 2Sweep every corner. Deliberately drag into all four corners and along the edges. Cells in the coverage grid light up as you touch them; any square that stays dark is a spot your trackpad never registered — a dead zone.
- 3Tap, click and scroll. Left-click, two-finger tap (which fires a right-click) and double-tap anywhere — the tap counters climb. Then two-finger scroll to watch the horizontal and vertical deltas accumulate.
- 4Read the capability panel. Each capability shows Ready, Pass or N/A so you can tell at a glance what your device reports — including whether it exposes real multi-touch and pressure, which many laptop pads don't.
How the touchpad test works
The tool is built entirely on the browser's Pointer Events — the same pointermove, pointerdown and pointerup signals every web page receives. As your cursor moves, each event carries a position and a pointerId; the page plots those positions as a fading trail and lights the coverage-grid cell underneath. Because it reads raw event coordinates rather than a smoothed cursor, a stuttering or teleporting trail is a faithful sign of a sensor or driver problem, not a rendering artifact.
Taps and scrolls are read the same honest way. A left-click is a pointerdown with button 0; a two-finger tap on a trackpad is delivered to the browser as a contextmenu (right-click) event; a double-tap arrives as dblclick. Two-finger scrolling is reported as wheel events, so the tool sums their horizontal and vertical deltas to show exactly how far and in which directions your gesture moved the page.
The honest catch: most laptop trackpads let the operating system interpret gestures before the browser sees them. Two fingers become a scroll, a pinch becomes zoom, and the browser is handed one cursor plus wheel events — not several independent contacts. So genuine multi-touch dots and analog Force-Touch pressure only appear on touchscreens and a handful of precision devices. The capability panel reports what your specific hardware and browser actually expose rather than pretending every pad is the same.
When a touchpad test helps
Buying a used laptop
Before you pay, sweep the whole pad and watch the coverage grid. A dead corner or a jumpy trail on someone else's machine is far easier to spot here than in a two-minute showroom check.
Chasing a jumpy cursor
If the pointer teleports or drifts, the trail makes it visible: you can see exactly where it snaps. That tells you whether it's a hardware fault, a dirty surface, or an aggressive palm-rejection setting.
Finding a dead zone
A trackpad that ignores one region is a classic ribbon-cable or wear failure. The coverage grid pinpoints the dead area so you can decide between a clean, a driver reinstall, or a repair.
After a driver or OS update
Updates sometimes break two-finger scroll, taps or gestures. Run the tap counters and scroll readout to confirm each gesture still fires before you go hunting through settings.
Diagnosing scroll problems
Scroll that jumps, reverses or drops out shows up in the delta readout. Watch whether both axes respond and whether the numbers climb smoothly or in erratic bursts.
Checking a touchscreen
On a touchscreen the multi-touch dots come alive — place several fingers and each gets its own numbered contact. It's a quick way to confirm all touch points and rule out a cracked digitizer zone.
Touchpad test glossary
- Pointer Events
- The modern browser input model that unifies mouse, pen and touch into one stream of events. Everything this tool measures comes from it.
- pointerId
- A unique number the browser assigns to each active contact. Multiple simultaneous pointerIds are what make a numbered multi-touch dot appear per finger.
- Precision Touchpad
- Microsoft's standard for trackpads that report rich multi-finger data to Windows. Precision pads expose smoother, more consistent gestures than older vendor drivers.
- Force Touch
- Apple's pressure-sensitive trackpad tech (and similar pads) that reads how hard you press. Browsers rarely expose its analog pressure, so it often reads as N/A here.
- Dead zone
- A region of the pad that never registers contact. On the coverage grid it stays dark no matter how many times you drag across it — usually wear or a loose cable.
- Jitter
- Small, random jumps in the reported position when your finger is moving smoothly or even still. It shows as a ragged, hopping trail instead of a clean line.
Frequently asked questions
How do I test my touchpad or trackpad?
Open this page on the laptop you want to check and, with one finger, move around the test surface — a fuchsia trail follows your cursor. Sweep into every corner to fill the coverage grid, tap and double-tap to climb the counters, and two-finger scroll to see the delta readout respond. A smooth trail, a fully lit grid, climbing counters and reacting scroll numbers mean your trackpad is working. Anything that hops, stays dark or ignores you points to the fault.
Why is my cursor jumping or drifting?
A jumpy cursor usually comes from three things: a dirty or damp pad surface, an overly aggressive palm-rejection setting, or a failing sensor or ribbon cable. Run the test with a clean, dry finger — if the trail teleports or snaps to fixed spots, that's hardware or driver jitter. If it only misbehaves when your palm is near the pad, it's palm rejection. Cleaning the surface fixes a surprising number of "broken" trackpads.
What is a dead zone and how do I find one?
A dead zone is a patch of the trackpad that no longer registers touch, often from wear or a partly disconnected cable. To find one, drag your finger deliberately across the entire surface and watch the coverage grid: cells light as you touch them, so any square that stays dark after you've clearly swept it is a genuine dead spot. A dead corner or stripe is a strong sign the pad needs a reseat or replacement.
Why does two-finger scroll not show up as multi-touch?
On most laptops the operating system interprets your two fingers as a scroll gesture and hands the browser wheel events instead of two separate contacts — so the scroll delta readout moves, but the multi-touch dots don't. That's expected, not a bug. Raw simultaneous contacts (and the numbered dots) mainly appear on touchscreens and a few precision devices that pass finger data straight through. The capability panel shows honestly which your device does.
Can this detect Force Touch or pressure sensitivity?
Only when your browser exposes it, which is uncommon. Pointer Events carry a pressure value, but most trackpads — including many Force Touch pads — report a flat default rather than a true analog reading, so the Pressure capability usually shows N/A. If your device and browser do pass real pressure through, pressing harder flips it to Pass. We'd rather say N/A than fake a reading your hardware isn't giving.
Does the test work on a touchscreen or phone?
Yes. On a touchscreen the same surface reads finger contacts directly, so the multi-touch dots light up — place several fingers and each gets its own numbered, coloured dot, which is a fast way to confirm every touch point works and spot a cracked digitizer area. Taps, the trail and the coverage grid all work on touch too; two-finger scroll behaves as your device's browser reports it.
Is this touchpad test free and private?
Completely. It's free, needs no sign-up, and runs entirely in your browser. Every pointer move, tap and scroll is processed on your device and never uploaded — there are no servers receiving your input. Only your theme and language preferences are saved, in this browser's local storage.
