What is the ideal projector screen size for my room?
The ideal projector screen size for your room depends on several factors, including the room’s dimensions, the projector’s resolution and brightness, and the desired viewing experience. A general rule of thumb is to choose a screen size that is between 1/3 to 1/2 of the room’s width. This will ensure that the image is large enough to be immersive, but not so large that it overwhelms the space.
For example, if your room is 12 feet wide, a screen size of 4-6 feet would be a good starting point. However, this is just a rough estimate, and you may need to adjust the screen size based on other factors, such as the projector’s throw distance and the room’s lighting conditions. It’s also a good idea to consult with a professional or use a projector screen size calculator to determine the optimal screen size for your specific setup.
