each factors in the projected image size.

The screen aspect ratio is 4:3 and the projected picture is 4:3
For example, if you are using an 120-inch screen, the recommended projection distance is
4400 mm and the vertical offset is 91 mm.
If your measured projection distance is 6.0 m (6000 mm), the closest match in the
column is 5500 mm. Looking across this row shows that a
150'' (about 3.8 m) screen is required.
