To determine the minimum and maximum diagonal size of an image when you know the projection distance:
pInches:
Maximum diagonal size = (0.6038 ⋅ projection distance) +
1.8898
Minimum diagonal size = (0.4631 ⋅ projection distance) + 1.4000
pCentimeters:
Maximum diagonal size = (0.6038 ⋅ projection distance) +
4.8001
Minimum diagonal size = (0.4631 ⋅ projection distance) + 3.5560
To determine the projection distance when you know the diagonal size of the screen image:
pInches:
Maximum projection distance = (2.1593 ⋅ diagonal size) −
3.0229
Minimum projection distance = (1.6562 ⋅ diagonal size) − 3.1291
pCentimeters:
Maximum projection distance = (2.1593 ⋅ diagonal size) −
7.6782
Minimum projection distance = (1.6562 ⋅ diagonal size) − 4.2068
