FAQ
How far should I sit from a 90 inch TV?
For a cinematic, immersive picture sit about 9 ft (2.74 m) away — the THX 40° angle. For a more relaxed, mixed-use setup go to about 12 ft (SMPTE 30°). With 4K you can sit as close as 7.5 ft without seeing pixels.
What size room do I need for a 90" TV?
Plan for a seating distance of roughly 9–12 ft. The screen itself is about 78.4" (199 cm) wide, so leave a little wall margin on each side.
Is a 90 inch TV too big?
Not if your seats are at least 9 ft away. Larger 4K TVs are easy to enjoy up close — most people end up wishing they bought bigger.
