THX viewing angle recommendations for home theater screens and HDTVs.
How do you calculate the best seat-to-screen distance for a plasma, LCD TV or projection screen? Divide the size of your screen by 0.84 (screen size is measured diagonally). For example, a 65-inch TV divided by 0.84 equals a = 77-inch viewing distance (6.5 feet).
Seat-to-screen Viewing Distance Calculations
For your HDTV setup if your TV is going in a living room with limited space, THX recommends the following:
- 35 inch class TV = 3.5-5 feet away
- 40 inch class TV = 4-6 feet away
- 50 inch class TV = 5-7.5 feet away
- 60 inch class TV = 6-9 feet way
- or use the formula, Diagonal TV size divided by 0.84 = Recommended viewing distance.
It might seem that THX is recommending a very large screen size for your room. But, it’s important to note two things:
1) THX screen size recommendations are based on recreating an immersive cinematic experience, and
2) the biggest complaint among TV buyers is that they wish they had bought a bigger set.
Make sure each seating position in your home theater has a clear site line to the screen. Try not to place the screen too high on the wall “ viewers should not have to look up more than 15°.
