Create a new document
1-Create a New-document
After launching InDesign, you’ll see the Start Screen. Click Create New to open the New Document dialog box. Or press Command+N (MacOS) or Control+N (Windows).
2-Select a Category
Select a category at the top such as Print, Web, or Mobile. These general categories start you off on the right foot by setting up some parameters for your project like the best color mode and units.Consider your project before choosing a category. For example, choose Print if you’re designing a business card, poster, or booklet; choose Web if you’re creating a mockup of a webpage, or a PDF that will be read onscreen.
Whether or not you start with a preset, you can customize your document in many ways — by typing exact dimensions, changing the measurement units, changing page orientation, and much more. Don’t worry about getting it right at this stage; you can edit all the settings after the document is created.Specify the number of pages and select Facing Pages to create a double-page spread layout used in magazines and books. Indicate the number of columns on your pages and the space between columns (Column Gutter).
4-Set margins, bleed, and slug
5-Change your document settings at any time
Great job setting up your first document. To change any document settings, go to File > Document Setup to change options like the document’s color mode (Intent), page size and orientation, number of pages, or add print bleed values from your print provider.
