Rule of thirds is fairly easy to grasp, but this simple concept can make you a really good designer.
What is the Rule of Thirds?
This rule states that if you have a canvas and divide it into three equal horizontal and three equal vertical sections, then the resulting grid will be a roadmap for placing your design elements.
Any efficient photo editing software will have the feature to automatically apply a rule of thirds grid to your canvas and crop accordingly if needed.
Use this grid as a guide
You must understand that symmetry and balance are not to be used interchangeably. Your design must be balanced, but it doesn’t necessarily have to be symmetrical.
The rule of thirds will help you in making a design that uses great balance and composition but is still visually interesting. A great starting point for an asymmetrical design is to move your key elements to the right or left side of the grid.
The grid is there to provide guidance for your design, but it isn’t a hard and fast rule. You are not required to align all of your elements to only one side.
Rule of thirds applies and printing media
However, there may be some cases when you might work with a uniquely shaped media which won’t allow the grid to help you because you will be unable to divide the canvas evenly.
If you are using a large photograph in your design or an image for your background which takes up the majority of your canvas, then the rule of thirds will be applied to the print design the same way it applies to an image or photograph.
When you are utilizing this technique, you should treat each panel of the marketing collateral as its own separate canvas.
