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.
