How to use the multitouch test
Place fingers on the test area one at a time, keeping the earlier ones down, and spread them out. Each point the screen reports gets a numbered circle, and the highest number reached is recorded as the most reported at once.
What this test checks
The browser reports each contact as a separate pointer with its own id, and the test tracks how many are active simultaneously. That count is the practical limit of your digitiser, which is what pinch to zoom, two-finger scrolling and on-screen game controls all depend on.
Fingers placed too close together can be merged into a single point, so spread them out before concluding the panel is limited. The operating system also claims some gestures before the page sees them, which is why very high finger counts can behave unexpectedly on tablets.
What the number should be
Most current phones report five or ten simultaneous points and tablets commonly manage ten, while older and budget panels stop at two. A device that used to manage ten and now stops at two has almost certainly had its digitiser damaged, or replaced with a lower-specification part.
Frequently asked questions
- How many touch points should my device support?
- Most modern phones report five or ten simultaneous points, and tablets commonly manage ten. Older or budget panels stop at two. What matters more than the exact number is whether it matches what your device is specified for.
- Why does my count stop lower than expected?
- Either the digitiser genuinely reports fewer points, or your fingers are too close together for it to separate them. Spread them out and try again before concluding anything — and note that a replacement screen fitted after a repair often supports fewer points than the original.
- Does the browser limit how many touches it reports?
- Browsers pass through what the panel reports, but the operating system may claim some touches for its own gestures. A four-finger swipe on iPadOS, for example, switches apps before the page ever sees it.
- Why does multitouch matter?
- Because pinch to zoom, two-finger scrolling, and most game controls all depend on more than one point being tracked at once. A panel that has dropped to reporting a single touch will feel broken in ways that are hard to describe until you test it.
