For a 16:9 aspect ratio:
- Diagonal measurement (D) = 120 inches
- Aspect ratio (AR) = 16:9
- Width (W) = √(D² / (AR² + 1)) = 104.72 inches
- Height (H) = W / AR = 58.86 inches
For a 4:3 aspect ratio:
- Diagonal measurement (D) = 120 inches
- Aspect ratio (AR) = 4:3
- Width (W) = √(D² / (AR² + 1)) = 96.92 inches
- Height (H) = W / AR = 72.69 inches
As you can see, the actual dimensions of a 120-inch projector screen vary significantly depending on the aspect ratio.
What About the Screen’s Gain and Material?
