How can you add a border to a slide in PowerPoint?

To add a border to a slide in PowerPoint, selecting "Format Background" and choosing the appropriate border options allows for precise control over the style and appearance of the border. This method enables users to customize the color, weight, and type of border they want to use, ensuring the border aligns with their presentation's theme and design.

While other options may seem viable, they do not provide the same level of customization or specificity regarding adding borders directly to slides. For instance, using the "Design" tab primarily influences overall slide design elements like background and color schemes, but it does not offer specific border settings. Similarly, applying a theme might incorporate various design elements, but it does not ensure that a border will be included or custom-fitted to the desired style. Finally, inserting a shape around the slide can visually create a border effect, but it is more of a workaround than a direct method for adding a border, as it requires additional steps to ensure the shape fits perfectly and achieves the desired aesthetic.
