What Is and How to Apply the Rule of Thirds in Illustration

For centuries, we have known that geometry plays a fundamental role in the composition of an image

Throughout history, the golden number has been heralded and, in most visual and aesthetic terms, it can embody an almost mystical perfection. The Ancient Greeks explained everything sacred through geometry, art, and mathematics, using the golden ratio as a symbol of excellence and divinity; this ratio is constantly repeated in nature and has been replicated in art over the centuries.

What is the rule of thirds?

The rule of thirds is an extreme simplification of the complicated golden ratio so acclaimed, applauded and used for centuries. It is arguably the simplest composition formula available, yet it works virtually every time it is applied.

To apply the rule of thirds, we can divide the composition space or canvas we are going to work into nine identical quadrants. This will generate four intersections at the central points of the composition, which are the points of tension that, in most illustrations, paintings, photographs, and visual compositions, most attract our gaze and seem more "pleasant" to us.

The rule of thirds in illustration

The world of art, with painting at its head, is the greatest exponent of the use of the golden ratio and the rule of thirds in particular. Just a quick browse through some of the most famous paintings in history will show that most of them strictly follow this mode of composition.

In film, photography, and design, to name but a few disciplines, it is also easy to see the application of the rule of thirds, and illustration is no exception.

To apply the rule of thirds in your illustrations, draw two horizontal and two vertical lines on the space you intend to work on, creating a grid of nine exactly equal spaces. From there, you can start sketching and placing the elements of your drawing, taking into account the effect of those points with a higher power of attraction.

Many, however, find composing according to the law of thirds too rigid and predictable. Keep in mind, therefore, that you can also choose to create compositions by placing the most important elements outside of the points marked by the law of thirds, intentionally challenging the established norm to create a different impression.

In the course Artist's Sketchbook for Illustration Projects, you will learn even more about the rule of thirds and how to apply it in from Aleix Gordo Hostau as he shows you how to document your creative process and use your sketchbook as a personal archive.
