This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The sizeY read-only property of the VRStageParameters interface returns the depth of the play-area bounds in meters.

The bounds are defined as an axis-aligned rectangle on the floor, for safety purposes. Content should not require the user to move beyond these bounds; however, it is possible for the user to ignore the bounds resulting in position values outside of this rectangle. The center of the rectangle is at (0,0,0) in standing-space coordinates.


var mySizeY = vrStageParametersInstance.sizeY;


A float representing the depth in meters.
