Save your custom page sizes as InDesign presets (CS/CS2/CS3/CS4)

When creating a new document, there are several generic page sizes you can choose from, or you can manually enter the custom width and height you need. More often, though, InDesign documents are set up using custom page sizes. Manually entering the same information over and over again is tedious and a waste of time. One option to speed up the process is to create document presets, where you enter the values in the New Document dialog box and then click the Save Preset button. Another option, which we'll explain how to do, is add your custom page sizes to the Page Size pop-up menu in the New Document dialog box.

To do this, locate the file New Doc Sizes.txt in the Adobe InDesign > Presets folder (In CS4, it's in the Adobe InDesign > Presets > Page Sizes > en_US folder) and open it. Then, follow the instructions in the file to add your custom page size to the list. After you list your custom page size, save and close the text file. Then, choose File > New > Document. In the New Document dialog box, simply choose your custom page size from the Page Size pop-up menu and click OK to get to work! Enjoy your DTP work!
