The most flexible foundation to support the designer working in two and three dimensions is that of the grid. The grid divides a two or three dimensional space into smaller compartments. The compartments may be the same or different size.
Within these fields there can be text and graphical elements arranged. This can help make the elements that have priorities stand out more clearly.
Using a grid structure is basically organising the information into the space allocated for it. The most important principle in using any grid system is that it can be used to establish consistency, unity and order.
A few basic rules for using a grid system:
– Use grid elements to help define the problem and establish design constraints
– Establish a hierarchy between elements, title, subheads, text, graphic elements and other devices
– Place text as a unit to avoid interrupting text with graphic elements
