Projection Distance and Size
Use the figures, 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.)
a is the distance (m, feet) between the
lens and the screen, and corresponds
to a range of 0.89 m (.9 ft.) to 10.93
m (35.86 ft.).
H is the height from the
image bottom to the center of the lens.
