All slides within PowerPoint are based on one of the available Slide Layouts (we call these just layouts for the rest of this tutorial). These layouts can be chosen when you add a new slide or you can even change the layout of your existing slides — both these options are accessible from the Home tab of the Ribbon. While these available layouts seem to cover most types of slides, you may sometimes want to create a new layout based on your individual requirements.
