One of the simplest guidelines for visually powerful PowerPoints is the Rule of Thirds.
The Rule of Thirds appears as early as 1797 (in a book by JT Smith) as a rule for good nature paintings. It is a guideline for composition that suggests placing key graphic elements along lines that divide your image into thirds, or at the intersections of those lines.
Imagine two vertical and horizontal lines running through your PowerPoint slide, dividing your slide into 9 areas of equal size. These lines intersect at four points - Sweet Spots. Using these lines and Sweet Spots can visually enhance and energise your slides.
People who believe in the Rule of Thirds claim that aligning a subject with these points creates more tension, energy and interest in the composition, as compared to placing the subject in the centre. Use the following 6 guidelines when you develop your next presentation.
Guideline #1 – Position the picture or text at a Sweet Spot
In the example, the key element is the red person. Rather than place the figure in the centre, I chose to position it in the top left of the slide. By placing key elements at one or more of these Sweet Spots, you achieve maximum impact.
 
Guideline #2 – Place key text along horizontal lines
We are tempted to place the horizon in the middle of the frame. This is generally not the best approach. In the example (right), I placed the horizon along the upper horizontal line. Additionally, the lower horizontal line is formed by the words and it divides the slide into thirds. The overall effect is balance between the two horizontal lines.
 
Guideline #3 – Place key illustrations along vertical lines
Composing your pictures based on a simple grid of thirds is a technique that movie producers, graphic designers and professional photographers use. Using the Rule of Thirds leads to pleasing and professional-looking imagery. When using upright pictures – align them to one of the vertical lines.
When doing close-ups of people, it is common to line up the body with a vertical line, and having the person's eyes in line with a horizontal one.
 
Rule #4 – Use both the Sweet Spots and the horizontal lines
In this example, the upper horizontal line carries the text. At the same time, the picture is placed on the lower right Sweet Spot. Ask yourself: “Are both the picture and the text obeying the Rule of Thirds?”   Rule #5 – Let the picture bleed to the edge of the slide
When using photographs, choose ones that bleed right to the edges of your slides. This is a good way to achieve impact. At the same time, try to choose ones that obey the Rule of Thirds.
Look for pictures with a white background, as it will blend perfectly with the clean, white slide background. The text can then be positioned with the most dramatic words - common sense - placed on a Sweet Spot.
 
Rule #6 – Put the main area of interest on a Sweet Spot
One tip is to use a much larger photograph that can be cropped to the Rule of Thirds. Or scale, crop, or position photographs to follow the rule.
When looking at pictures, use your mental viewfinder to find a small area within a larger photograph that you can use. By cropping asymmetrically, you can often create a more pleasing effect.
Also look for pictures with large areas of uniform colour on which you can place text or a solid one-colour background.
 
Maybe you want to create some sort of grid on which to build your slides. In the beginning, grids can save you time and ensure that your design elements fit more pleasantly on the display.
Studies have shown that, when viewing images, people’s eyes usually go to one of the Sweet Spots rather than the centre of the image. Using the Rule of Thirds works with this natural way of viewing an image, rather than against it. |
