A layout is a drawing or plan showing the positioning of elements on a page. Templates provide preset layouts with standardized formatting. Designers use non-printing guides to help precisely place objects, including margin guides along the edge of the page, column guides to control text flow, and ruler guides for alignment. Considerations for layout include formatting, page size, master pages to maintain consistency, and prototypes to mock up the final design. Common layout types are business cards, letterheads, flyers, brochures, newsletters, advertisements, magazine pages, and infographics.
