There are a lot of ways to calculate seating distance. Included angle is the best method, with a cross check on visual acuity. This gives you an immersive experience without eye strain or head movement.
SMPTE standard EG-18-1994 recommends a minimum viewing angle of 30 degrees
THX recommends a viewing angle of 36 degrees and an absolute minimum of 26 degrees.
Using the more modern THX recommendations, I sit 12' back from my 106" diagonal 94" wide screen, giving me an included angle of 36 degrees.
I can tell you it is a perfect distance - immersive but not visually fatiguing at all.
For a 120" diagonal screen the THX recommended seating distance is 13.4' (36 degrees) and the maximum is 18.9' (26 degrees)
