What are Grids?
Grid structures are useful devices to bring all elements of the design into a harmonious relationship. Simple structures sub-divide the available space into proportioned divisions eg thirds or quarters (both horizontally and vertically). Margins are used in order to contain the elements within the edges of the format/page. A space is often inserted between the divisions so that elements such as the type are contained within a prescribed width and do not clash with the elements in the next column. These divisions are often known as units and the overall space a field eg an A4 sheet divided into three both horizontally and vertically has a 9-unit field. Not all designs employ a grid; simple typographic arrangements might make stronger relationships between individual words to enhance meaning and communication. For more on Grids visit The Grid System
