What is a grid?
The main idea behind grid-based designs is a solid visual and structural balance for the piece that you are creating with them. Sophisticated layout structures offer more flexibility and enhance the visual experience for people interacting or observing the piece of graphic design.The grid provides a structured framework for a layout, that should not limit design or make creativity suffer. Rather than forcing you to work rigidly within its confines, the grid layout should work for you, allowing you to dictate the look and feel of your publication.
“The Golden Section is a ratio which is evident throughout the universe as the number Phi. You can use this ratio to good effect in design by making sure that elements of your grid conform to this ratio. Using the Golden Section can ensure a natural sense of correct composition, even though it is based in mathematics it will ‘feel’ right.” Mark Boulton
Two column grids
Two-column grids are mostly used in books, newsletters, or narrow publications where the column width is limited. Although this layout is very simple, you can still achieve variety by adding for example, images and headlines and sells that can span both columns on the page.
However, for publications such as magazines or other types of books, the text columns in a two-column grid would generally be too wide for comfortable reading so that the audience doesn’t feel that they have to read too much.
Three column grids
Three column grids give more flexibility than two-column grids because text and images can span one, two, or all of the columns. Three-column grids work for most layouts and are particularly suited to publications that do not require complex arrangement of text and images.
