The image size projected by a projector is determined by the distance between the projector itself and the screen. Thus, to get a suitable projected image size, simply adjust the distance between your Nebula and the screen.

Moving the projector closer to the screen will make the projected image smaller, and moving the projector farther from the screen makes the projected image bigger. When the projector is placed at a proper distance, you can get a suitable projected image size for a great watching experience.

Regaring Nebula Projectors with zoom function (like Cosmos, Cosmos Max, Solar or Solar Portable) also support zoom function, you can also adjust the projected image size through zoom by selecting Settings > Projector Settings > Zoom. However, these projectors only support zooming out to project a smaller image. If you want to project a larger image, please move your Nebula farther from the screen.
