Navigator: maxTouchPoints property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.
The maxTouchPoints read-only property of the
Navigator interface returns the maximum number of simultaneous touch
contact points that are supported by the current device.
Value
A number.
This value is hardware-dependent. Desktop computers without a touchscreen (Mac, Windows and Linux) return 0 while smartphones (Android and iOS) typically return 5.
Example
js
if (navigator.maxTouchPoints > 1) {
// Device supports tracking at least 2 touch points; offer complex
// interaction gestures such as swiping with two/three fingers
} else {
// Device only has 1 touch point or is not a touch screen.
// Offer basic gestures such as dragging and clicking
}
