Formulas

The Projection Formulas use the image width for calculation. Image height is the same for all aspect ratios, only horizontal image size varies when using a 16:10 aspect ratio screen. 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 “W” for a 16:10 aspect ratio image in the Projection Formulas.

Refer to the diagrams (page 5) and charts below for popular screen sizes 16:10 screens:

Projection Formulas:

 

Definitions:

NP01FL:

C = 0.8260W – 1.33

 

W = Image Width

NP02ZL:

C(Wide) = 1.2120W – 1.798 ------

C(Tele) = 1.5770W – 1.795

H = Image Height (size)

Standard:

C(Wide) = 1.5330W – 2.022 ------

C(Tele) = 2.0390W – 2.015

C = Throw distance

NP03ZL:

C(Wide) = 1.9910W – 2.830 ------

C(Tele) = 3.1460W – 2.840

 

NP04ZL:

C(Wide) = 3.0300W – 4.830 ------

C(Tele) = 4.8465W – 4.850

16:10 Screen Formulas:

NP05ZL:

C(Wide) = 4.7888W – 7.625 ------

C(Tele) = 7.2779W – 7.645

W = H x 16/10

 

 

 

H = W x 10/16

 

 

 

Screen Diagonal = W x 18.868/16

Note: Tilting the front of the projector or down by more than 45° from level could reduce lamp life by up to 20%.
