Despite its name, the Rule of Thirds can be a difficult concept to grasp. It relates to the Golden Ratio, a measure of proportion. The Phi Grid is an earlier grid that is a more precise representation of divine proportion. Its four rectangles are all proportional to one another, but it is a bit unwieldy when used in design.
The Rule of Thirds is an important compositional principle. Using the technique, artists often create compositions with a certain balance and harmony. This principle can be applied to law firms as well. Generally, the rule says that a piece should have three lines running vertically, two horizontally, and one on each side. This creates four points of intersection, called power points, crash points, and points of interest. The rule also dictates that important compositional elements are placed along these intersections.
