Let the dimensions of your canvas unleash your idea’s full potential. Whether your aim is pixel perfection or ensuring compatibility across devices, understanding how to change the size of a slide in Google Slides is a small but crucial skill that can help you create an impressive professional presentation. 

What are the different Google Slides dimensions used for?

When giving a PowerPoint presentation on different types of projectors and monitors, you might not be able to adjust the size of the slide relative to the projector’s screen size. On the other hand, Google Slides allows you to change the aspect ratio of your presentations, with options including 16:9 (widescreen), 16:10, 4:3 (standard), and custom.

1. Widescreen – 16:9

This aspect ratio has been commonly used for modern presentations since 2008, replacing the older 4:3 aspect ratio due to changing display standards. It’s ideal for monitors, projectors, and TVs worldwide.

2. Widescreen – 16:10

Less common than 16:9 but found on tablets and computer monitors, this aspect ratio is closer to the Golden Ratio (1.618), offering a slightly different visual experience. Manufacturers mostly stick with 16:9 due to production cost concerns.

3. Standard – 4:3

The standard layout shows content slightly smaller compared to widescreen layouts. Initially popularized by older versions of PowerPoint and Google Slides, it is still relevant for smaller slides and screens where standard size is preferred. This aspect ratio is suitable for images, diagrams, and tables to avoid stretching on widescreen displays.

4. Custom Size

Google Slides allows custom slide sizes in inches, centimeters, points, or pixels. This is useful for adjusting layouts for specific documents, images, or infographics. Examples include switching to Letter (8.5 x 11 inches) or A4 size (8.27 inches). It provides flexibility for precise adjustments using pixels, points, or centimeters.

Remember that if you change the original aspect ratio of your presentation, any components and pictures will get jumbled, and you’ll have to adjust them one by one in the slides or your master slides.

Why Should I Know How To Change Slide Size In Google Slides?
