# presentationScreenSize

The size of the screen presenting the image, with the format [width, height] in meters.

## Declaration

```swift
var presentationScreenSize: SIMD2<Float> { get }
```

## Discussion

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.
