GoKawiilSMPTE guidelines outline ideal TV viewing distances based on screen size
The Society of Motion Picture and Television Engineers has established viewing distance recommendations tied to screen size and field of view. Its standard 30-degree rule suggests sitting about 1.6 times a TV's diagonal size away for general viewing, while a 40-degree rule (1.2 times diagonal) offers a more immersive experience, and a 62-degree rule caters to those wanting an extreme, theater-like setup.
