For example, if you are using a 120-inch screen, the recommended projection distance is 1481 mm and the vertical offset is 274 mm.

If your measured projection distance is 2.0 m (2000 mm), the closest match in the "Distance from screen (mm)" column is 1852 mm. Looking across this row shows that a 150'' (about 3.8 m) screen is required.
