What is a good throw ratio?
Understanding throw ratio helps with selecting a projector that is suitable for your experience. The LF1 works best with throw ratios between 0.82-1.77. Keep in mind your environment setup, any installation limitations, and your potential projected image size.
How do you calculate throw ratio?
Throw Ratio = Throw Distance / Image Width, which can calculate a distance as 2.5m from the wall for projection of a 100-inch image with a 16:9 aspect ratio (image width is approximately 2.2m or 87.1inches).
How far should I sit from a 120 screen?
If your family likes being near the center of the theater, then choose a screen size which has about 10 inches of diagonal for each foot of viewing distance. That’s about 120-inch diagonal for a 12 foot viewing distance.
