What is the Rule of Thirds In Art?

The Rule of Thirds in Art: Guide for Professional Artists (2)

The rule of thirds is a guideline for both artists and photographers. It says that if you divide your composition into thirds, either vertically or horizontally, and then place focal areas of your scene at the meeting points of them, you will get a more pleasing arrangement and layout for your compositions.

Details: The Rule of Thirds In Art

Composition is one of the most important things you need to plan in your painting whether you are painting landscapes, still lifes, or painting the figure and portrait. It determines the success or failure of your painting.

An important technique you should know about is the Rule of Thirds. Although this is often referred to as a rule, I prefer to call it a technique. This is because making it a rule is too rigid: there are ways of making good compositions without using this principle. However for beginners, the rule of thirds is a good guideline.

The rule of thirds relates to another principle called the “Golden Ratio”. This is a mathematical relationship of proportion that is often found in nature. This ratio has been used by artists and architects throughout the centuries, including the designers of the Parthenon in Athens, Salvador Dali, Le Corbusier, and Leonardo da Vinci.

Example Of The Rule Of Thirds

Here is one of my paintings of an old wooden house in a Chinese village called Xinchang, near Shanghai. I painted this during an event in which Chinese and American painters were invited to participate in a week-long plein air event with a final exhibition in an old historic building in the ancient village.

Note where the most saturated color is: the light on the blue door. This is an example of a focal area. Now to see the rule of thirds in action, let’s add a grid over the painting that is divided in to thirds.

The Rule of Thirds in Art: Guide for Professional Artists (4)

You can see that the blue door lies on the line of the first third division in the painting. In this case it does not lie at the intersection of the gridlines, but along one of them. If you have a small focal area or focal point, you could put it at the intersection. A longer focal area such as this one falls along one of the lines.

The circle shows the intersection of the division of thirds. The HSB shows the saturation of the blue color: 76%, which is quite high. I am using the principle of contrast of saturation to highlight the focal area.

In this way, by using the rule of thirds in art you can make your paintings more interesting.

Using Apps To Apply The Rule Of Thirds In Art

There are several apps you can use on your phone to put a grid on top of a photograph to identify the positions where the third division points lie. If you search the app store for ‘photo grids’ you will find them. I use an app called Grid #. This one has worked quite well for me.

Origins Of The Rule Of Thirds In Art History

The origins of the rule of thirds go back to classical Greek Architecture to and Renaissance paintings. It is also commonly used as a compositional tool by photographers. If you examine many classical buildings and Renaissance paintings you will see how often the main characters are placed at the intersection of the third division lines. However, it is not always the case and be cautious not to be too dogmatic about this rule. There are often other, more important things to think about in composition such as rhythm and groupings that might override this rule. As always, the rule of thirds is just a technique in your toolbox, and not to be always followed religiously.

Relationship Of The Rule Of Thirds In Art To Other Principles Of Art

I suspect that this rule is more of a simple way to avoid putting your focal area, or center of interest, right in the center of the painting, rather than a prescription of exactly where to place it. It is never a good idea to put the most interesting part of the painting in the dead center of your painting.

Also, it probably works because a division of two thirds 0.66 approximates to the concept of agolden ratiowhich is a ratio of 0.62. The Golden Ratio is a pleasing division of space as it is based on natural mathematical laws.

Here is a video by Apple showing how to use an iPhone to view the rule of thirds grids.

As a seasoned art enthusiast and expert, I bring a wealth of knowledge and practical experience to the discussion of artistic principles. Having explored various art forms and studied the works of renowned artists, I aim to enrich your understanding of the Rule of Thirds in art as presented by Barry John Raybould in his article "Cat. No. 1413 Montenegro Valley."

Now, let's delve into the key concepts presented in the article:

1. The Rule of Thirds in Art: The Rule of Thirds is a fundamental guideline for artists and photographers alike. It advocates dividing the composition into thirds, both vertically and horizontally, and placing focal areas at the intersection points. This approach enhances the arrangement and layout of compositions, contributing to a more visually appealing result.

2. Composition Importance: The article emphasizes the critical role of composition in painting, asserting that it determines the success or failure of a piece. The Rule of Thirds is presented as a technique rather than a strict rule, offering flexibility for artists. While not mandatory, it serves as a valuable guideline, especially for beginners.

3. Golden Ratio and Rule of Thirds: The Rule of Thirds is linked to the "Golden Ratio," a mathematical relationship of proportion found in nature. This ratio, approximately 0.62, has been historically used by artists and architects, including prominent figures like Salvador Dali and Leonardo da Vinci. The Rule of Thirds serves as a simplified way to avoid placing the focal point directly in the center, aligning with the pleasing division of space offered by the Golden Ratio.

4. Example of the Rule of Thirds: The article illustrates the Rule of Thirds with a painting of an old wooden house in Xinchang, China. The most saturated color, the light on the blue door, serves as the focal area. By overlaying a grid on the painting, the author demonstrates how the blue door aligns with the first third division line, showcasing the practical application of the Rule of Thirds.

5. Using Apps for Rule of Thirds: Modern technology is acknowledged as a tool for applying the Rule of Thirds. The article mentions using phone apps, such as Grid #, to overlay a grid on photographs and identify the positions of third division points.

6. Origins in Art History: The origins of the Rule of Thirds are traced back to classical Greek architecture and Renaissance paintings. It has been a compositional tool used by artists throughout history. While common, the article advises against being too dogmatic about this rule, acknowledging the importance of other compositional elements like rhythm and groupings.

7. Relationship to Other Principles of Art: The author speculates that the Rule of Thirds may be a simple way to avoid placing the focal area in the center of the painting. It suggests that the division of two-thirds approximates the concept of the Golden Ratio, providing a pleasing division of space based on natural mathematical laws.

In conclusion, the Rule of Thirds in art, as discussed by Barry John Raybould, offers a valuable technique for artists to enhance their compositions. It connects to broader principles of art, including the Golden Ratio, and has roots in classical art and architecture. While not a strict rule, it serves as a guiding principle for achieving visually engaging artworks.
