# proposedSize

The size proposed to the root view.

```
@MainActor final var proposedSize: ProposedViewSize { get set }
```

## Discussion

The default value of this property, [`unspecified`](/documentation/SwiftUI/ProposedViewSize/unspecified),
produces an image that matches the original view size. You can provide
a custom [`ProposedViewSize`](/documentation/SwiftUI/ProposedViewSize) to override the view’s size in one or
both dimensions.
