For your next presentation, keep your audience engaged with slides that are compatible with the device or screen you’re presenting with. The purpose of your presentation and the viewing platform or format will help determine the size that you should use for your presentation.
What are the most common sizes?
Commonly known as the standard aspect ratio, 4:3 is used where the presentation is intended for print distribution as it can easily adapt to the A4 or Letter paper size. While 4:3 was the standard screen size, this is no longer the case as all modern projectors and computer screens now come standard with wide screens.
Commonly known as widescreen, 16:9 is used for highly visual content and should be your default choice of size for creating presentations. This is because almost all modern projector screens, televisions, and computers display come in widescreen as a 16:9 layout. With recent advances in technology that is seeing widescreen devices becoming the norm, 16:9 is now considered the standard size for on-screen presentations over 4:3.
