This multi touch test shows every finger on your screen as a numbered, colored point with its own trail, so you can see how many touches the screen tracks at the same time and whether any of them drop out, jump or swap. Each point lists its ID, position, contact size and pressure where your screen reports them, and the browser's own touch limit sits next to the count so you know what to aim for. It works on Android phones, iPhones and iPads, Windows touch laptops, Chromebooks and touch monitors, and the full screen view gives five or ten fingers room to spread out.
How to run the multi touch test
- Press Full screen test so every finger has room. Lay a phone flat on a table.
- Put one finger down and hold it. Circle 1 appears with its ID and position.
- Add fingers one at a time, keeping the others still, until the count stops rising. Most at once keeps the highest number.
- Slide all your fingers around together. Every circle should follow its own finger smoothly, without swapping numbers or vanishing.
- Bring two fingers close together, then move them past each other. The screen should keep them as two separate points.
- Lift your fingers and press Copy results for a report you can share.
On an iPad, four and five finger pinches and swipes go to the Home Screen and the app switcher. Turn off four and five finger gestures in Settings, then Multitasking & Gestures, before you test five fingers.
What the readouts mean
| Readout | What it tells you | Normal result |
|---|---|---|
| Touches now | Fingers the screen reports right now | The number of fingers you have down |
| Most at once | The highest count during this test | Reaches the browser limit |
| Browser limit | Touch points your browser says the screen supports | Usually 5 or 10 |
| ID | The number the browser gives each touch | Stays the same while that finger stays down |
| Position | Where each finger is, in screen points from the top left | Follows the finger smoothly |
| Contact size | Width and height of each touch | Grows as you press flatter, or shows Not reported |
| Pressure | Touch pressure from 0 to 1 | Not reported on most screens |
| Touch rate | Touch updates per second that reach the browser | Often 60, 90 or 120, the screen's refresh rate |
How many touch points screens support
| Device | Touch points the browser usually reports |
|---|---|
| iPhone and iPad in Safari | 5 |
| Android phones and tablets | 5 or 10 |
| Windows touch laptops and tablets | 10 |
| Touch monitors | 10 on most current models, 2 on some older ones |
| Chromebooks with a touch screen | 10 |
More points do not make a screen better for everyday use. Two fingers cover pinch and rotate, and three or four cover system gestures. Piano, drum and multiplayer games are where five to ten points matter.
The count stops below the browser limit
- Fingers too close. When fingertips touch each other, the screen sees one large contact. Keep about a finger width between them.
- A system gesture took over. Xiaomi, OnePlus and many other Android phones use a three finger swipe for screenshots, iPads use four and five finger gestures, and Windows 11 uses three and four finger touch gestures, which you can turn off in Settings, then Bluetooth & devices, then Touch. The system takes the touches and the browser cancels them.
- A screen protector or moisture. Both weaken the touch signal, so the last fingers added are the first to go missing. Dry the screen and test without the protector.
- The hardware limit. Some budget tablets and older touch monitors track only two or five points, whatever the browser reports.
Touches swap numbers, jump or merge
Two circles that trade numbers when your fingers pass close to each other, or a circle that leaps across the screen, mean the touch controller lost track of a finger and picked it up again. A little of this when fingers almost touch is normal. If it happens with fingers well apart:
- Unplug the charger and run the test again. Electrical noise from a charger makes touch points jitter and jump.
- Clean and dry the screen, and remove the screen protector.
- Restart the device to reset the touch controller.
- On older two point touch monitors, two fingers on one line can produce false points at the other corners of the shape they make. That is a limit of the screen, not a fault.
If points still jump with the charger off and the screen clean, run the touch screen test grid over the area where it happens to check for a dead zone, and the hands off watch for ghost touch problems.
A finger disappears while it is still down
A circle that vanishes while your finger stays on the glass was dropped by the screen or cancelled by the system:
- Palm rejection. A flat finger or thumb can look like a palm, and the screen ignores it. Use fingertips.
- Curved edges. Phones with screens that curve over the sides ignore some touches on the curve.
- System gestures. The log lists touches that the system cancelled, which points to a gesture setting rather than the screen.
- Dry or very cold fingers. Touch screens sense the small electrical charge in your skin, and dry or cold fingertips give a weaker signal.
Touch rate on gaming phones
Gaming phones advertise touch sampling rates of 240 Hz or more. The Touch rate readout shows how many touch updates reach the browser. When the sub line says raw touch samples, the browser passes on every report from the screen. Otherwise the updates are limited to the screen's refresh rate, which you can check with the refresh rate test. A web page cannot confirm the full rate a game sees, but a touch rate well below the refresh rate points to a power saving mode.
What this test cannot tell you
The page sees only the touches the browser passes on. Touches on the browser's bars, the system's edge gestures and gestures the system keeps never reach it. The browser limit is what the browser reports, and the hardware may track more in apps. Pressure shows only where the screen reports it, and no browser measures force in grams. Multi finger gestures on a laptop touchpad are a different check, done in the trackpad test, and pens and styluses have their own pen pressure test. A Wacom, Huion or XP-Pen tablet on a computer goes through the drawing tablet tester. Phones used for motion controls in games can be checked with the gyroscope test.
Multi touch test questions
How many touch points does my phone support?
Put fingers down one at a time in this test until Most at once stops rising. Safari on iPhone and iPad reports 5 touch points, and Android phones usually report 5 or 10. The Browser limit line under the count shows the number your browser gives for your screen.
Can I run a multi touch test on an iPhone?
Yes. Open this page in Safari and press Full screen test. Safari keeps its status bar and toolbar visible, so start your fingers inside the page area. Five fingers is the most Safari reports.
Is there a multi touch test for Android without an app?
Yes, this page runs in Chrome or Samsung Internet with nothing to install. Android also has a built in view: turn on Developer options, then Pointer location, and the bar at the top shows how many fingers are down.
Why does my screen only detect two touches?
Some budget tablets and older touch monitors track only two points. If your browser limit is higher than what you can reach, the fingers may be too close together, or a system gesture is taking the touches. Spread your fingers a finger width apart and turn off three finger screenshot gestures, then test again.
Why do my touches vanish when I put three fingers down?
Many Android phones use a three finger swipe for screenshots, Windows 11 uses three and four finger gestures, and iPads use four and five finger gestures. The system takes those touches and the browser cancels them, which the touch log marks as cancelled by the system. Turn the gesture off while you test.
