What Size TV for a Bedroom 12.5 feet Away?
Bedrooms usually have closer seating and smaller walls. A 43" to 55" TV is typical, but a 65" can work if you watch from the bed 8+ feet away.
Recommended size
85"
SMPTE OK — 28° field of view
At 12.5 feet in a Bedroom, a 85" 4K TV gives you a 28° 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.
