The normalized pressure of the pointer input in the range of 0 to 1, where 0 and 1 represent the minimum and maximum pressure the hardware is capable of detecting, respectively. For hardware that does not support pressure, including but not limited to mouse, the value MUST be 0.5 when the pointer is active and 0 otherwise.
This property is Read only .
var pressure = pointerEvent.pressure;
pressureThis example illustrates using the pressure property.
When a pointerdown event is fired, different functions are called depending on the value of the event's pressure property.
someElement.addEventListener('pointerdown', function(ev) {
if (ev.pressure == 0) {
// No pressure
process_no_pressure(ev);
} else if (ev.pressure == 1) {
// Maximum pressure
process_max_pressure(ev);
} else {
// Default
process_pressure(ev);
}
}, 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 0 instead of 0.5 on hardware that doesn't support pressure.
