How to Optimize Image Size and Distance

Consult the table below to find the optimal image sizes achievable when the
projector is positioned at a desired distance from the screen.
If the projector is 2 m from the screen, good image quality is possible for the
image sizes around 50".
Note: Remind as below figure, the space of 76 cm height is
required when the projector is located at 2 m distance.
