Formulas: 16:10 Aspect Ratio (PA653U/PA803U—WUXGA)
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: 16:10 Screen Formulas
NP11FL: C = 0.807W – 1.354 W = Image Width W = H x 16/10
NP12ZL: C(Wide) = 1.185W – 1.794 ------ C(Tele) = 1.541W – 1.794 H = Image Height (size) H = W x 10/16
NP13ZL: C(Wide) = 1.488W – 1.974 ------ C(Tele) = 2.970W – 1.972 C = Throw distance Screen Diagonal = W x 18.868/16
NP14ZL: C(Wide) = 2.961W – 4.844 ------ C(Tele) = 4.737W – 4.844
NP30ZL: C(Wide) = 0.808W – 1.537 ------ C(Tele) = 1.054W – 1.537
NP40ZL: C(Wide) = 0.807W – 1.535 ------ C(Tele) = 1.131W – 1.632
NP41ZL: C(Wide) = 1.323W – 1.763 ------ C(Tele) = 3.034W – 1.539
NP42ZL: C(Wide) = 2.929W + 5.143 ------ C(Tele) = 5.878W + 4.320
