# aspectRatio(_:contentMode:) Constrains this view’s dimensions to the specified aspect ratio. ``` nonisolated func aspectRatio(_ aspectRatio: CGFloat? = nil, contentMode: ContentMode) -> some View ``` ## Parameters `aspectRatio` The ratio of width to height to use for the resulting view. Use `nil` to maintain the current aspect ratio in the resulting view. `contentMode` A flag that indicates whether this view fits or fills the parent context. ## Return Value A view that constrains this view’s dimensions to the aspect ratio of the given size using `contentMode` as its scaling algorithm. ## Discussion Use `aspectRatio(_:contentMode:)` to constrain a view’s dimensions to an aspect ratio specified by a using the specified content mode. If this view is resizable, the resulting view will have `aspectRatio` as its aspect ratio. In this example, the purple ellipse has a 3:4 width-to-height ratio, and scales to fit its frame: ``` Ellipse() .fill(Color.purple) .aspectRatio(0.75, contentMode: .fit) .frame(width: 200, height: 200) .border(Color(white: 0.75)) ```  --- Copyright © 2026 Apple Inc.
