How to optimize image size and distance

projector is positioned at a desired distance from the screen.
If the projector is 2.0 m from the screen, good image quality is possible for
image sizes between 41" and 65".
Note: Remind as below figure, the space of 81 cm height is
required when located at 2 m distance.
