We explored and complained about how PowerPoint 2016 has made widescreen (16:9) as the default aspect ratio for new presentations. Although you can change all these new presentations from Widescreen (16:9) to Standard (4:3) aspect ratio quite easily, it can be a pain to remember doing so each time you create a new presentation! Of course, if you are happy with 16:9 slides, then you need not read the rest of this tutorial — for everyone else, we’ll show how you can set your default aspect ratio to Standard (4:3).
