Summary
Returns the Y radius of the ellipse that most closely circumscribes the area of contact with the touch surface. The value is in CSS pixels of the same scale as Touch.screenX
.
This value, in combination with Touch.radiusX
and Touch.rotationAngle
constructs an ellipse that approximates the size and shape of the area of contact between the user and the screen. This may be a large ellipse representing the contact between a fingertip and the screen or a small one representing the tip of a stylus, for example.
Note: This attribute has not been formally standardized. It is specified in the Touch Events – Level 2 Draft specification and not in Touch Events Recommendation. This attribute is not widely implemented.
Syntax

Return value
yRadius
- The Y radius of the ellipse that most closely circumscribes the area of contact with the screen.
