Multi-Touch Test
Count how many touch or pointer points the browser delivers at the same time during this visit. That max is not the touchscreen's rated point count. A browser or OS can cap it below the hardware.

A check means the browser delivered that many together this visit. It is not a hardware rating.

With exactly two pointers down, the square follows the distance and angle between them. A jump means those samples arrived that way. This is not a hardware smoothness rating.
Pressure and contact size
Touch the pad to see each finger's data.
Shown only from numbers the browser sends. A pressure of 0.50 and no size usually means those readings were not provided. That is common, and it is not a fault this page measured.
Palm rejection and edge filtering can hide contacts near the bezel or ones that look like a resting hand. Spread your fingertips and keep them off the very edge to see if a higher count arrives. That count is still only what the browser delivered this visit.
Reading the results
What the count is
Each pointer on the pad (a finger, a pen, or a held mouse button) is one contact the browser delivered with its own ID. "Max this visit" is the most that were down together during this visit. It is not the touchscreen's rated point count and not a spec-sheet figure. "Browser reports" is navigator.maxTouchPoints. A browser or OS can cap either number below the hardware. Safari on iPhone and iPad often reports 5 through that API even when a spec sheet says something else. "Saved in this browser" is the highest count kept in localStorage, which can be from an earlier visit, and it is not a hardware rating.
A spec sheet is a different number
Boxes for tablets, kiosks, and portable monitors often say "10-point multi-touch". This page cannot read that rating. If 10 pointers arrive together, the browser delivered 10 this visit. That does not certify the panel. If the count stalls lower, spread your fingertips away from the edges and try again. A stall can be a browser or OS cap, palm rejection, or a system gesture. It does not, by itself, mean the spec sheet was wrong.
Why contacts go missing
A thick screen protector can make a light touch drop out. Palm rejection can ignore contacts that are close together or near the bezel. System gestures can cancel them: iPad four-finger and five-finger gestures, and some Android three-finger screenshots. This page counts a cancel when the browser sends pointercancel. If the circles jump or the square stutters, the touch screen test can help look for spots that do not respond. This page still cannot measure the digitiser itself.

Frequently asked questions
What does the max number mean?
Max this visit is the most touch or pointer points the browser delivered at the same time during this visit. It is not the touchscreen's rated point count and not a spec-sheet figure. A browser or operating system can cap how many points reach the page, so a lower number does not by itself mean the panel is rated lower.
What is Browser reports?
It is navigator.maxTouchPoints, the figure this browser exposes. It can be lower than a spec sheet. Safari on iPhone and iPad often reports 5 even when a spec sheet names a higher count. A mouse or trackpad often reports 0. The report is not a measurement this page made of the hardware.
Why did the count stop short of the spec sheet?
The browser or operating system may be capping the stream. Palm rejection, a screen protector, or a system gesture can also drop contacts. iPad four-finger and five-finger gestures, and some Android three-finger screenshot gestures, cancel touches. This page adds to the cancel count when the browser sends pointercancel for a touch. That is not a lab test of the digitiser.
Does seeing 10 points mean the screen supports 10?
No. It means 10 pointers were down together in this browser during this visit. It does not certify the hardware. Stopping below 10 does not disprove a spec sheet, because the browser or operating system may have capped the count.
How do I leave full screen?
Use the X button at the top right, or press Escape on a keyboard. The X stays visible and tappable. The hint text can fade. Closing or reloading the page also leaves full screen. iPhone Safari does not offer the Fullscreen API, so the pad covers the browser window instead, and the same X closes that cover.
Do a mouse, a pen, and pinch count?
Yes. A mouse, a pen, and a finger are all pointers. The count is how many the browser has down together. With exactly two pointers, the square follows the distance and the angle between them. Pressure and contact size are shown only when the browser sends finite numbers. A pressure of 0.50 and a missing size are the usual stand-ins when the browser has no real reading.
Is the saved best uploaded?
No. The highest count is saved in this browser with localStorage so a later visit can show it. Nothing is sent to a server. If storage is blocked, the test still runs and the saved best stays at 0. The saved number is an earlier delivery in this browser, not a hardware rating.
