Graphic designers combine art and technology to communicate ideas through images and the layout of web screens and printed pages. They may use a variety of design elements to achieve artistic or decorative effects. They develop the overall layout and production design for advertisements, brochures, magazines, and corporate reports. Graphic designers work with both text and images. They often select the type, font, size, colour, and line length of headlines, headings, and text. Graphic designers also decide how images and text will go together on a page or screen, including how much space each will have. When using text in layouts, they collaborate closely with writers who choose the words and decide whether the words will be put into paragraphs, lists, or tables.
