# LayoutProperties Layout-specific properties of a layout container. ``` struct LayoutProperties ``` ## Overview This structure contains configuration information that’s applicable to a layout container. For example, the [`stackOrientation`](/documentation/SwiftUI/LayoutProperties/stackOrientation) value indicates the layout’s primary axis, if any. You can use an instance of this type to characterize a custom layout container, which is a type that conforms to the [`Layout`](/documentation/SwiftUI/Layout) protocol. Implement the protocol’s [`layoutProperties`](/documentation/SwiftUI/Layout/layoutProperties) property to return an instance. For example, you can indicate that your layout has a vertical stack orientation: ``` extension BasicVStack { static var layoutProperties: LayoutProperties { var properties = LayoutProperties() properties.stackOrientation = .vertical return properties } } ``` If you don’t implement the property in your custom layout, the protocol provides a default implementation that returns a `LayoutProperties` instance with default values. ## Topics ### Creating a layout properties instance [`init()`](/documentation/SwiftUI/LayoutProperties/init()) Creates a default set of properties. ### Getting layout properties [`var stackOrientation: Axis?`](/documentation/SwiftUI/LayoutProperties/stackOrientation) The orientation of the containing stack-like container. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
