Whenever you create a new presentation using PowerPoint for the iPad, you will first have to choose a Theme that will determine the appearance of your slides. A Theme is essentially something that determines the colors, fonts, effects, backgrounds, and layouts available to you as defaults within the slides you create. Do notice that by default, all the Themes you see sport Widescreen aspect ratios (16:9). If you are creating a presentation that you will deliver elsewhere, then there’s nothing to worry about. However if you are planning to present this new presentation from the iPad, then you will want to make sure that the slides you create use a Standard (4:3) aspect ratio.
