{{APIRef("WebXR Device API")}}{{SeeCompatTable}}{{SecureContext_Header}}

The read-only {{domxref("XRWebGLLayer")}} property framebufferHeight indicates the height of the framebuffer, in pixels.

You can get the width of the framebuffer using the {{domxref("XRWebGLLayer.framebufferWidth", "framebufferWidth")}} property.

Value

The height in pixels of the XR device's framebuffer. Each of the framebuffer's attachments (pixel, depth, color, and/or stencil buffers, for example) are all this many pixels tall.

Examples

This snippet fetches the framebuffer's width and height for later use.

let glLayer = xrSession.renderState.baseLayer;
gl.bindFramebuffer(gl.FRAMEBUFFER, glLayer.framebuffer);

frameWidth = glLayer.framebufferHeight;
frameHeight = glLayer.framebufferHeight;
