The Projection Formulas use the image width for calculation. Image width is the same for all aspect ratios, only vertical image size
varies. For proper projector placement, determine the image width for a desired screen size. Use the Screen Formulas below to
calculate all screen dimensions. Plug in the image width for “W” in the Projection Formulas.
Refer to the diagrams and charts for popular screen sizes on page 2 and 3:
Projection Formulas: Definitions: 4:3 Screen Formulas:
NP11FL: C = 0.827W – 1.374 W = Image Width W = H x 4/3
NP12ZL: C(Wide) = 1.214W – 1.794 ------ C(Tele) = 1.578W – 1.794 H = Image Height (size) H = W x 3/4
NP13ZL: C(Wide) = 1.525W – 1.974 ------ C(Tele) = 3.043W – 1.972 C = Throw distance Diagonal = W x 5/4

Lens Shift Range for Desktop and Ceiling Mount
Application
The diagram below shows the location of the image
position in the lens. The lens can be shifted within
the shaded area as shown using the normal
projection position as a starting point.
Note: Lens shift feature is not available with
NP11FL (rear lens). NP11FL should be used only
for “zero degree” / “no-offset” applications.
Maximum Possible Range for NP12ZL, NP13ZL,
NP14ZL, NP15ZL, NP32ZL:
Towards ceiling/floor: 0.5H (0.6H for PA571W)
Away from ceiling/floor: 0.1H
Right: 0.3W
Left: 0.3W
(W: width of projected image, H: height of projected
image)
Note: Horizontal lens shift range for the PA521U is
