What Size TV for a Family Room 4.5 meters Away?
Family rooms are casual viewing spaces with mixed seating. A 65" to 75" TV fits most family rooms without overwhelming the space.
Recommended size
85"
Too small — 24° field of view
At 4.5 meters in a Family Room, a 85" 4K TV gives you a 24° horizontal viewing angle. SMPTE recommends at least 30°; THX recommends 36° for a theater-like experience.

Why the math works this way
We use the SMPTE 30° minimum field-of-view standard and the THX 36° theater ideal. A 4K TV lets you sit closer than old 1080p rules suggested, so most buyers should size up if the wall and budget allow. The recommendations above are based on the actual horizontal screen width of each common size, not a rule of thumb.
