Projection distance (when aspect ratio 16:10)
The following shows the dimensional relationship between the projector and projection surface.
The dimensions included in the following table have a slight error. Also, when keystone correction is performed
on the projector side, correction is made so that the projected image size becomes smaller than the speci
fi
ed
screen size.

Projection distance formula (when aspect ratio 16:10)
To use an image size not listed in this manual, check the projected image size SD (m) and use the respective
formula to calculate projection distance (L).
The unit of the formula is all “m”. (Value obtained by the following calculation formula contains a slight error.)
When calculating a projection distance using image size designation (value in inches), multiply the value in
inches by 0.0254 and substitute it into SD in the formula for calculating the projection distance.
Minimum projection
distance (LW)
L = 1.2976 × SD - 0.0385
Maximum projection
distance (LT)
L = 2.7999 × SD - 0.0379
