Know the screen size to get the throw distance:

Minimum projection distance (m) = minimum focal length (m) x screen size (inches) ÷ LCD size (inches)

Maximum projection distance (m) = maximum focal length (m) x screen size (inches) ÷ LCD size (inches)

The projection distance is known to get the screen size:

Maximum projection screen (m) = projection distance (m) x LCD size (inches) ÷ minimum focal length (m)

Minimum projection screen (m) = projection distance (m) x LCD size (inches) ÷ maximum focal length (m)

another:

4:3 screen size (inches) = [screen width (m) × 5 / 4] × 100 / 2.54

16:9 screen size (inches) = [screen width (m) × 18.257 / 16] × 100 / 2.54
