Projection Distance and Size

Use the fi gures, tables, and formulas below to determine the projection size and projection distance. (Projection sizes are approximate values for full-size picture with no keystone adjustment.)

Screen As seen from above

Lens center

As seen from side

Lens center

a (cm) = projection size (inches) x 1.433 – 13.32

H (cm) = projection size (inches) x 0.1868

“a” is the distance (cm) between front edge of the projector and the screen, and cor- responds to a range of 40 cm to 177 cm. “H” is the height from the image bottom to the center of the lens.
