Any other projection distance can be obtained according to the screen dimensions (m) using the following calculations.

The distance is shown in units of meters. (The calculated distance may contain a certain error.) If the screen dimensions are written as “SD",

 

For 4:3 aspect ratio

For 16:9 aspect ratio

 

 

 

Screen height (SH)

= SD(m) × 0.6

= SD(m) × 0.490

 

 

 

Screen width (SW)

= SD(m) × 0.8

= SD(m) × 0.872

 

 

 

Minimum distance (LW)

= 1.1941 × SD(m) - 23.27

= 1.301 × SD(m) - 23.27

 

 

 

Maximum distance (LT)

= 1.4335 × SD(m) - 23.67

= 1.561 × SD(m) - 23.67
