Multi-Touch & Stylus Tester
Test every touch point on your touchscreen and check stylus pressure, tilt and contact size.

How it works
Put as many fingers on the grey area as you can and hold them there. Every contact gets its own coloured dot, a row in the live table and an entry in the event log, so a dead zone in the digitiser or a finger the panel refuses to register is immediately obvious. The Max simultaneous figure is the highest number of pointers your screen reported at the same time — compare it with Browser maxTouchPoints, the number the browser claims your hardware supports. Ten is typical for a modern phone or tablet; five is common on cheaper panels.
Stylus users get more: draw with the pen and the tool reads the pressure (0 to 1), the tilt
angles in degrees and the reported contact size, so you can confirm pressure sensitivity is
actually reaching the browser. The page uses the standard
pointerdown, pointermove, pointerup and
pointercancel events, which cover mouse, touch and pen with one API. If your
browser does not support Pointer Events, a message says so and the tester stays inert rather
than reporting misleading results. Everything runs locally in plain JavaScript — nothing is
uploaded and nothing is recorded.
Frequently asked questions
How many touch points does my screen support?
The Browser maxTouchPoints figure on this page is the number your browser reports for the hardware, and Max simultaneous is the number the tester actually saw at the same time. Most modern phones and tablets handle 10 contacts, many laptop touchpads and budget touch panels stop at 5, and some kiosk or car screens only manage 2. If the observed number is lower than the reported one, press with more fingers spread further apart before assuming a fault.
How do I test a touchscreen for dead spots?
Drag one finger slowly across the whole test area, edge to edge and corner to corner, and watch the coloured trail it leaves behind. A dead zone shows up as a gap in the line or a dot that jumps past a region instead of moving through it. Repeat with a second finger, since some digitiser faults only appear when more than one contact is active.
Does this test stylus pressure and tilt?
Yes. When you draw with a pen, the live pointer table shows the pressure as a value from 0 to 1, the tilt angles in degrees on both axes and the reported contact width and height, and the Peak stylus pressure tile keeps the hardest press. Those values come straight from the browser's Pointer Events, so if they stay at 0 your pen, driver or browser is not passing pressure through to web pages.
