# aspectRatio(_:contentMode:)

Constrains this view’s dimensions to the aspect ratio of the given size.

## Declaration

```swift
nonisolated func aspectRatio(_ aspectRatio: CGSize, contentMode: ContentMode) -> some View

```

## Parameters

- `aspectRatio`: A size that specifies the ratio of width to height to use for the resulting view.
- `contentMode`: A flag indicating whether this view should fit or fill the parent context.

## Return Value

Return Value A view that constrains this view’s dimensions to aspectRatio, using contentMode as its scaling algorithm.

## Discussion

Discussion Use aspectRatio(_:contentMode:) to constrain a view’s dimensions to an aspect ratio specified by a CGSize. If this view is resizable, the resulting view uses aspectRatio as its own aspect ratio. In this example, the purple ellipse has a 3:4 width-to-height ratio, and scales to fill its frame: Ellipse()     .fill(Color.purple)     .aspectRatio(CGSize(width: 3, height: 4), contentMode: .fill)     .frame(width: 200, height: 200)     .border(Color(white: 0.75))
