Frequently Asked Questions
What field of view should I choose?
THX recommends around a 30-degree field of view for an immersive cinema-like experience, while 20-26 degrees is more comfortable for family rooms with mixed use like TV and gaming.
Does resolution affect screen size recommendations?
Yes. Higher resolutions like 4K and 8K allow you to sit closer to a larger screen without seeing individual pixels, so they support bigger screens at the same viewing distance.
Should I measure to the seating or the wall?
Always measure from where viewers will actually sit to where the screen will be mounted, not the overall room length.
