# vImage.Size A structure that contains width and height values. ``` struct Size ``` ## Topics ### Initializers [`init(cvPixelBuffer: CVPixelBuffer)`](/documentation/Accelerate/vImage/Size/init(cvPixelBuffer:)) Creates a size with dimensions specified by a Core Video pixel buffer. [`init?(exactWidth: T, height: T)`](/documentation/Accelerate/vImage/Size/init(exactWidth:height:)-9nwk0) Creates a size with dimensions specified as floating-point values. [`init?(exactWidth: T, height: T)`](/documentation/Accelerate/vImage/Size/init(exactWidth:height:)-4ygbk) Creates a size with dimensions specified as integer values. [`init?(exactly: CGSize)`](/documentation/Accelerate/vImage/Size/init(exactly:)) Creates a size with dimensions specified as a Core Graphics size value. [`init(width: Int, height: Int)`](/documentation/Accelerate/vImage/Size/init(width:height:)-fzcb) Creates a size with dimensions specified as integer values. [`init(width: vImagePixelCount, height: vImagePixelCount)`](/documentation/Accelerate/vImage/Size/init(width:height:)-8ly3k) Creates a size with dimensions specified as unsigned integer values. ### Instance Properties [`let height: Int`](/documentation/Accelerate/vImage/Size/height) The height of the size structure. [`let width: Int`](/documentation/Accelerate/vImage/Size/width) The width of the size structure. ## Relationships ### Conforms To [`Equatable`](/documentation/Swift/Equatable) --- Copyright © 2026 Apple Inc.
