There are two places in Finale where you can set the page size: the Page Format for Score dialog box, Document Menu > Page Format > Score, or the Page Layout Tool. A page in Finale can be as huge or as tiny as you can imagine—but some printers are limited in the sizes of paper they can handle.
Note: If you plan to print on any size paper larger than 8.5 by 14 inches, see Printing for special instructions. For other instructions on mixing and matching page size layouts, and a more complete discussion of page layout, see Page layout.
