How far away from a surface does my projector need to be?
Each projector is different, so there isn't a standard distance that works for all situations.
Consider factors like the size of the area you're hoping to cover, the brightness of your projector, and the mounting options you have for your space.
For the best results, you should make sure that your projector can cast a bright enough image and you're able to mount it in a location where it can be hidden.
We encourage you to play around with your projector's placement and find the solution that works best for you.
The best way to know for sure is to learn about the concept of "throw distance".
