PointerEvent: width 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 width read-only property of the
PointerEvent interface represents the width of the pointer's contact
geometry along the x-axis, measured in CSS pixels. Depending on the source of the
pointer device (such as a finger), for a given pointer, each event may produce a
different value.
If the input hardware cannot report the contact geometry to the browser, the width
defaults to 1.
Value
The width of the event's contact area (in CSS pixels).
Examples
This example illustrates using the PointerEvent interface's
width and
height properties to calculate the contact area.
target.addEventListener("pointerdown", (ev) => {
// Calculate the contact area
const area = ev.width * ev.height;
});
