Multi-Touch Test
Check how many simultaneous touches your phone or tablet screen can track. Place several fingers on the pad — each gets a numbered circle, and the peak keeps the highest count you reach.
Open this page on the phone or tablet you want to test. A mouse counts as a single pointer.
Place several fingers on the pad — the counters show how many simultaneous touches your screen tracks.
Lower fingers one by one. Where the count stops is your screen’s real limit.
Not a fault — ten points, one per finger, is the industry standard.
Circles that flicker, vanish, or drift while fingers hold still suggest a failing digitizer.
Multi-touch is what makes a touchscreen more than a pointer: pinch-to-zoom needs two clean contact points, rotation gestures need three, and mobile games expect both thumbs plus more. It also fails silently. A cracked corner, a cheap replacement digitizer, or a dying touch controller usually keeps single taps working — so the phone feels fine — while the second or third finger is dropped. Worth thirty seconds before buying a used phone, after a screen repair, or when a game keeps missing your second thumb.
Each finger arrives as a separate pointer through the browser’s Pointer Events API, and the test draws a numbered circle for each. Touches now counts what the digitizer tracks this instant; Peak at once remembers the highest it reached. Browser limit reads navigator.maxTouchPoints — the count the hardware claims to support, so a screen advertising ten but tracking two has a fault the spec sheet won’t admit. Use full-screen mode to fit all ten fingers. Everything runs locally in your browser.
Why does the counter stop at 10?
Ten points — one per finger — is the industry standard for phone and tablet digitizers, and the controller firmware stops reporting contacts beyond its designed limit. A device capping at exactly 10 is working perfectly. Budget phones and e-readers may stop at 2 or 5, which still covers pinch-to-zoom. What is not normal: a peak stuck at 1 on hardware claiming more, contacts vanishing when a second finger lands, or circles drifting while your fingers hold still — signs of a damaged digitizer or a bad replacement screen. Run the Touch Screen Test to check for dead regions.
Typical multi-touch limits by device
| Device | Typical touch points | Notes |
|---|---|---|
| Budget phones & e-readers | 2–5 | Covers pinch-to-zoom; multi-finger gestures may struggle |
| Modern smartphones | 10 | The industry standard — one point per finger |
| Tablets (iPad, Android) | 10 | Two-hand input for drawing, gestures, split-keyboard typing |
| Windows touch laptops & 2-in-1s | 10 | Certification requires at least 5; most panels ship with 10 |
| Interactive whiteboards & kiosks | 20–40+ | Built for several people using the display at once |
