Example
Suppose you want a 120-inch screen with a projector that has a throw ratio of 1.5–1.8.
The calculator estimates:
- Minimum Distance = 11.8 feet
- Maximum Distance = 14.2 feet
This means your projector should be installed somewhere within this range to produce a perfect 120-inch image.
Without a calculator, finding this distance manually would require complex calculations and repeated testing.
