# presentationScreenSize The size of the screen presenting the image, with the format [width, height] in meters. ``` var presentationScreenSize: SIMD2 { get } ``` ## Discussion For immersive viewing modes (`.spatialStereoImmersive` and `.spatial3DImmersive`), this property represents the screen size of the non-immersive version of that mode (`.spatialStereo` and `.spatial3D` respectively). This property is expressed relative to the local coordinate space of the entity the `ImagePresentationComponent` is assigned to. To calculate the size of the screen in world coordinate space, multiply `presentationScreenSize` by the entity’s world scale. --- Copyright © 2026 Apple Inc.
