Calculated tables of diagonal TV size and viewing angle
How much of your field of vision does that big TV fill up?
Find the diagonal dimension that matches your TV. Either the diagonal 16:9 or
4:3 number depending on the aspect ratio of your TV.
The feet column is distance away from the TV.
The 16:9 and 4:3 columns have the horizontal degrees of vision that are filled.
The "angle height" column is the number of vertical degrees of vision filled.
The 4:3 screen fits into the 16:9 screen like:
16
+----+--------+----+
| | | |
| | 4:3 | | 9
| | | |
+----+--------+----+
Notes:
THX suggests a 30 degree TV viewing angle.
THX recommends a 36 degree Cinemascope movie theatre image.
Front row in a movie theatre is about a 90 degree angle.
Joe Kane recommends a 7 foot wide project for all FP's (7",8",9" lenses)
in 16:9 a 7 foot wide screen is 96" diagonal
in 4:3 a 7 foot wide screen is a about 105" diagonal
