 Hi, I'm Laura from TechSoup, and I'm really excited to help you learn how to use Adobe InDesign Creative Cloud 2015. Let's learn how to set up a custom-sized document. But you can also make it bigger or smaller, as needed, using the stills you'll learn in this video. First, open InDesign, choose the Edit menu and navigate to Preferences. Here at the bottom of the menu, and then choose Units and Increments. Next, let's set the measurements. Set Horizontal and Vertical both to Inches and click OK. If at any point you need to undo a step, press the Control key and then type Z. Command Z on a Mac. In the File menu, choose New, and in the New Flyout menu, choose Document. In the New Document window, set Page Size to Custom. You could also choose at this point to have a standard-sized document, but in this case, we want you to see how you can customize documents for your non-profit or library's needs. In the Name field, type outside envelope, set the width to 7.25 inches and the height to 5.25 inches. Then click OK. In the New Document window, check to make sure that the Page Size field is set outside envelope. Set all of the margins to a quarter of an inch, that's 0.25 inches, and click OK. Your new document for the outer envelope will open. It should look like this. Now you are ready to place images and text. So now that you can set up documents, practice on your own.
