Projection distance formulas
Any other projection distance can be obtained according to the screen dimensions (m) by using the following
calculations.
The calculated distance may contain a certain error.
If you want to calculate the projection distance with projected image size SD (unit: inch) by substituting, please
assign 0.0254 times to the SD value.

For 16:10 aspect ratio
= 0.530 × SD(m)
= 0.848 × SD(m)
= 1.0037 × SD(m) - 0.0290
= 1.6273 × SD(m) - 0.0292
For 4:3 aspect ratio
= 0.6 × SD(m)
= 0.8 × SD(m)
= 0.9461 × SD(m) - 0.0295
= 1.5324 × SD(m) - 0.0272
For 16:9 aspect ratio
= 0.490 × SD(m)
= 0.872 × SD(m)
= 1.0316 × SD(m) - 0.0290
= 1.6725 × SD(m) - 0.0292
For 16:9 aspect ratio
= 0.490 × SD(m)
= 0.872 × SD(m)
= 1.0307 × SD(m) - 0.0295
= 1.6696 × SD(m) - 0.0272
For 4:3 aspect ratio
= 0.6 × SD(m)
= 0.8 × SD(m)
= 1.1363 × SD(m) - 0.0290
= 1.8422 × SD(m) - 0.0292
For 16:10 aspect ratio
= 0.530 × SD(m)
= 0.848 × SD(m)
= 1.0028 × SD(m) - 0.0295
= 1.6244 × SD(m) - 0.0272
