+# ScreenSizer
+
+<DocsDemo>
+  <ScreenSizerDemo />
+</DocsDemo>
+
+Adds a `<TresObject3D />` wrapper that scales to "screen space". By default `1` THREE world unit will be translated to 1 screen pixel.
+
+E.g. a BoxGeometry with a height, width, and depth of 100 each, will be scaled to 100 screen pixels in each dimension.
+
+## Usage
+
+<<< @/.vitepress/theme/components/ScreenSizerDemo.vue
+
+## Props
+
+Inherits all props from `THREE.Object3D`.
