Why Do I Need to Change the Slide Size on Google Slides?

Not everyone will need to change the slide size on their Google Slides presentations. Google Slides defaults to a commonly used size but there are some key reasons why it can be helpful. 

• Different screens. Different monitors have different aspect ratios and it's useful to adapt to them. 16:9 for instance is widescreen and your presentations will look better if they fit accordingly on screen.
• Flexibility. Not sure what screen your presentation will be on? Go with 16:9. 4:3 used to be the standard but more screens use widescreen. However, if you know it will be viewed on a mobile device, stick with 4:3.
• Printouts. Are you planning on printing out your slides? 4:3 is the best ratio for this situation.
