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.


var contactWidth = pointerEvent.width;

Return value

The width of the event's contact area (in CSS pixels).


This example illustrates using the PointerEvent interface's width and width properties to calculate the contact area.

target.addEventListener("pointerdown", function(ev) {
   // Calculate the contact area
   var area = ev.width * ev.height;
 }, false);

1. From version 41: this feature is behind the dom.w3c_pointer_events.enabled preference (needs to be set to true). To change preferences in Firefox, visit about:config.

2. Returns values in screen pixels instead of CSS document pixels.
