For example, if you are using an 120-inch screen, the recommended projection distance is 2422 mm and the vertical offset is 91 mm.

If your measured projection distance is 3.0 m (3000 mm), the closest match in the "Distance from screen (mm)" column is 3028 mm. Looking across this row shows that a 150'' (about 3.8 m) screen is required.
