PointerEvent: width property - Web APIs | MDN

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;
  },
  false,
);
