# FormPresentationSizing

The size is appropriate for forms and slightly less wide than.page

## Declaration

```swift
struct FormPresentationSizing
```

## Overview

Overview On iOS, .form sizing enforces a platform-defined floor for the vertical and horizontal dimensions. On macOS, no floor is enforced, however a maximum proposed height is derived from the presenter height. To achieve presentations outside of these bounds, see PresentationSizing.fitted or implement your own custom PresentationSizing. note: form
