Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the projected image size.

If you need a 4:3 screen to project a 4:3 picture and your measured projection distance is 3000 mm, please refer to Table A1 on page 14. The closest match in the "Distance from screen (mm)" column is 2933 mm. Looking across this row shows that a 80'' (about 2.0 m) screen is required.
