# UIPrintPaper The size of paper for a print job and the rectangular area that the content prints within. ``` class UIPrintPaper ``` ## Overview In most cases, UIKit automatically creates an instance of [`UIPrintPaper`](/documentation/UIKit/UIPrintPaper) that is appropriate for a print job. The UIKit framework has default paper sizes based on a print job’s output type ([`outputType`](/documentation/UIKit/UIPrintInfo/outputType-swift.property) is a property of the [`UIPrintInfo`](/documentation/UIKit/UIPrintInfo) class). If the output type is [`UIPrintInfo.OutputType.photo`](/documentation/UIKit/UIPrintInfo/OutputType-swift.enum/photo), the default paper size is 4x6 or A6 or some other standard size, depending on locale; if the output type is [`UIPrintInfo.OutputType.general`](/documentation/UIKit/UIPrintInfo/OutputType-swift.enum/general) or [`UIPrintInfo.OutputType.grayscale`](/documentation/UIKit/UIPrintInfo/OutputType-swift.enum/grayscale), the default paper size is US Letter (8 1/2 by 11 inches) or A4 or some other standard size, depending on locale. Applications may have special requirements for paper sizes. For example, a word-processing application may have items of “stationery” in which printable content must be drawn. If your application fits the special case, the delegate of [`UIPrintInteractionController`](/documentation/UIKit/UIPrintInteractionController) can implement the [`printInteractionController(_:choosePaper:)`](/documentation/UIKit/UIPrintInteractionControllerDelegate/printInteractionController(_:choosePaper:)) method of the [`UIPrintInteractionControllerDelegate`](/documentation/UIKit/UIPrintInteractionControllerDelegate) protocol to return a suitable print paper object. One way to do this is to call the [`bestPaper(forPageSize:withPapersFrom:)`](/documentation/UIKit/UIPrintPaper/bestPaper(forPageSize:withPapersFrom:)) class method of [`UIPrintPaper`](/documentation/UIKit/UIPrintPaper), passing in a array of print paper objects representing the paper sizes supported by a printer. The print paper object returned from this method represents the paper size best matched to the size requirement of the application. The printable rectangle ([`printableRect`](/documentation/UIKit/UIPrintPaper/printableRect)) is the imageable area for the printer on a paper of a given size. If you are using a [`UIPrintPageRenderer`](/documentation/UIKit/UIPrintPageRenderer) object to draw the content for printing, the rectangle stored in the [`printableRect`](/documentation/UIKit/UIPrintPaper/printableRect) property is stored in the page renderer’s property of the same name and the paper size used for a print job is stored as part of the [`paperRect`](/documentation/UIKit/UIPrintPageRenderer/paperRect) property. ## Topics ### Getting the paper size and the printing area [`paperSize`](/documentation/UIKit/UIPrintPaper/paperSize) The size of the sheet to use for printing. [`printableRect`](/documentation/UIKit/UIPrintPaper/printableRect) The rectangle that represents the portion of the paper that can be imaged upon. ### Obtaining the best paper size for printing [`bestPaper(forPageSize:withPapersFrom:)`](/documentation/UIKit/UIPrintPaper/bestPaper(forPageSize:withPapersFrom:)) The print-paper object that UIKit determines to be the best for a print job based on the specified page size and the paper size–imageable area combinations specific to the printer. ### Deprecated [`printRect()`](/documentation/UIKit/UIPrintPaper/printRect()) Deprecated. --- Copyright © 2026 Apple Inc.
