What Size TV for a Home Theater 1.5 meters Away?
Home theaters are built for immersion. Go as big as your wall allows — often 75" to 85" — and prioritize a 4K OLED or premium mini-LED.
Recommended size
43"
THX ideal — 35° field of view
At 1.5 meters in a Home Theater, a 43" 4K TV gives you a 35° 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.
