# Set document margins

Document margins let you establish the content area of your page. These margins are simply guides that let you establish a consistent layout across your entire comic.

- Open the Document sidebar by clicking on the Document button in toolbar.
- In the Margins section, enter new margins values. Your changes are made as soon as you hit enter or tab to the next fields.

  Margins are revealed as guide lines when you drag elements such as panels around the page. Your elements will snap to the margins when they come close, making it easy to get things lined up correctly.

Note: For Blank comics, margins are initially established by the Page Setup template. To adjust the default margins for new Blank comics, see Paper Sizes
