VRStageParameters
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The VRStageParameters
interface of the WebVR API represents the values describing the stage area for devices that support room-scale experiences.
Note: This interface was part of the old WebVR API. It has been superseded by the WebXR Device API.
This interface is accessible through the VRDisplay.stageParameters
property.

Deprecated Read only Non-standard-

VRStageParameters.sizeY
Deprecated Read only Non-standard-
Returns the depth of the play-area bounds in meters.
Examples
js
const info = document.querySelector("p");
let vrDisplay;
navigator.getVRDisplays().then((displays) => {
vrDisplay = displays[0];
const 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}`;
}
});
Specifications
This interface was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.
Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers [1].
