What aspect ratio should I use for my projection screen?
Planning and Practical Considerations
The most common aspect ratio for event projection is 16:9 (HD widescreen), which matches the native format of most video content, cameras, and presentation software. This is the safe default for conferences, general sessions, and most corporate events.
Ultra-wide ratios like 3:1 or 32:9 are used for panoramic stage backdrops and immersive environments, but they require multiple blended projectors and custom content. Other ratios (4:3, 21:9) are used for specific creative or legacy requirements. Your aspect ratio should be driven by your content format and creative intent first, then the screen and projector configuration is built to match.
