TV viewing distance

Recommended viewing distance from screen size and shape — the field-of-view bands used by THX and SMPTE guidance.

Screen size → panel dimensions and viewing distances at 40°/30°/20° field of view.

THX-style 40° fills more of your view; 30° is the common mixed-use pick; 20° suits long reading or work.
