Projection distance worksheets
The tables on the following pages provide installation information for all native image sizes. The minimum
ceiling height is based on an image 30 inches (762 mm) from the floor; if the image is lower, the minimum
ceiling height is reduced by the corresponding measurement.
Use the worksheets, the illustrations, and the information in the tables on the following pages to determine
the projection distance and placement of the wall plate.
3. Using the tables on pages 19 to 24, select the largest image size available for your
