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.
var info = document.querySelector('p');
var vrDisplay;
navigator.getVRDisplays().then(function(displays) {
vrDisplay = displays[0];
var stageParams = vrDisplay.stageParameters;
// stageParams is a VRStageParameters object
if(stageParams === null) {
info.textContent = 'Your VR Hardware does not support room-scale experiences.'
} else {
info.innerHTML = '<strong>Display stage parameters</strong>'
+ '<br>Sitting to standing transform: ' + stageParams.sittingToStandingTransform
+ '<br>Play area width (m): ' + stageParams.sizeX
+ '<br>Play area depth (m): ' + stageParams.sizeY
}
