The aspect ratio of your slides is an important aspect to consider as it can affect how your presentation is perceived by your audience. The aspect ratio refers to the proportional relationship between the width and height of a rectangle, such as an image, video, document, or slide.
There are two main aspect ratios used today - 4:3 and 16:9. 4:3 was the standard aspect ratio in the pre-widescreen era of standard definition television, but with the high-definition revolution, 16:9 has become the norm. Most modern laptops, including MacBook Pros, have a widescreen display, making 16:9 a more practical choice for presentations.
We recommend using a 16:9 aspect ratio for your pitch deck. This is because 16:9 is 78% wider than 4:3, and most computer displays now have a resolution of 16:10 or 16:9. Converting 4:3 to 16:9 requires cutting spaces from the top and bottom of the slide, while converting 16:9 to 4:3 involves cutting from the side pillars.
If you're using PowerPoint, you can find instructions on how to change the aspect ratio to 16:9 here: https://support.microsoft.com/en-us/office/change-the-size-of-your-slides-040a811c-be43-40b9-8d04-0de5ed79987eFor Google Slides, follow these steps: https://support.google.com/docs/answer/3447672?co=GENIE.Platform%3DDesktop&hl=enIf you're setting the slide size manually, you can use this calculator: https://video-pitch.com/check-ratio
