What Size TV for a Primary Bedroom 10 feet Away?
Primary bedrooms often have more wall space and a viewing distance of 9–11 feet. A 55" to 65" TV is the sweet spot for most master suites.
Recommended size
85"
THX ideal — 34° field of view
At 10 feet in a Primary Bedroom, a 85" 4K TV gives you a 34° 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.
