Make sure that you know whether you must create widescreen or standard slides for your next presentation.

The same goof up happened, but at yet another conference! The text size on the slide was teeny-weeny, and you could not see much, even if you squinted your eyes. This time, the problem was not that the presenter had used 8 point text on the slide; this text was 20 points, and that did not make it too small. Even then, you still could not read the text!
Yet, the presenter was referring to numbers on the slide repeatedly, and the audience was supposed to read the content and comment!
The problem may have been the projection screen which was quite small. However, I had projected my slides on the same projection screen, and the slide content was always readable. Clearly something was amiss. The problem was that a 16:9 Widescreen slide was projected on a Standard 4:3 projector/screen, thus making the slide's screen estate very less indeed.
This idea can be better explained with a visual. Look at Figure 1 below, which shows four thumbnails. The two thumbnails on the left represent actual Standard (4:3) and Widescreen (16:9) slides which project on a Standard (4:3) projection screen, as shown in the two thumbnails on the right.
Figure 1: Slides projected on a standard projection
The top example of a Standard slide (4:3) displayed on a Standard (4:3) projection screen works perfectly. However, the bottom example of a Widescreen slide (16:9) shown on the same Standard (4:3) projection screen is not perfect! You see vast, empty areas above and below the slide that are essentially non-slide areas. These non-slide areas represent 25% of screen real estate lost! Moreover, that is not even the worse worry because your slide text will also reduce in size proportionately and become difficult to read.
The other side of the coin also has the same issues, and Figure 2 explains this better. The two thumbnails on the left represent actual Standard (4:3) and Widescreen (16:9) slides which project on a Widescreen (16:9) projection screen, as shown in the two thumbnails on the right.
Figure 2: Slides projected on a widescreen projection
Note that the bottom example of a Widescreen slide (16:9) displayed on a Widescreen (16:9) projection screen works perfectly. Now project a Standard (4:3) slide on the same projection screen (16:9), and you will see large areas on the left and the right of the slide that essentially are empty, non-slide areas. These non-slide areas represent 25% of screen real estate lost! And that’s better than the previous example because at least your slide text will not reduce in size proportionately – so at least you are left with the same readability factor for your text!
