■ Screen Size and Projection Distance A Projection distance (cm) B Distance from the center of the lens to the base of the screen (This changes depending on the setting for vertical lens shift.) (cm) C Center of lens Projection Distance Formula 11 Projection distance ( ①) formula Minimum Projection distance (cm) = Projection screen size (inches) × 2.95848 - 3.5728 Maximum Projection distance (cm) = Projection screen size (inches) × 4.7743 - 3.5078 Projection distance ( ①) formula Minimum Projection distance (cm) = Projection screen size (inches) × 3.34923 - 3.5728 Maximum Projection distance (cm) = Projection screen size (inches) × 5.40488 - 3.5078 Projection distance ( ①) formula Minimum Projection distance (cm) = Projection screen size (inches) × 3.04074 - 3.5728 Maximum Projection distance (cm) = Projection screen size (inches) × 4.90704 - 3.5078 Projection distance ( ①) formula Minimum Projection distance (cm) = Projection screen size (inches) × 3.26665 - 3.5728 Maximum Projection distance (cm) = Projection screen size (inches) × 5.27161 - 3.5078 Projection distance ( ①) formula Minimum Projection distance (cm) = Projection screen size (inches) × 3.2067 - 3.5728 Maximum Projection distance (cm) = Projection screen size (inches) × 5.17486 - 3.5078
