2022-10-19

The size of the projector determines the viewing effect and experience, and designers need to grasp these dimensions:
1. The best viewing size for a projector
If the projector is set in the living room, the optimal viewing distance is calculated by the following formula: the length of the curtain * 0.87 = the optimal viewing size
For example, if the length of the curtain is 2500mm and 2500*0.87, then the distance between the sofa and the curtain is ≈2200mm.

2. Projection size of the projector
Different projector lenses are different, so their throw ratios are also different, and the throw ratio is controlled at 1.2: 1 is the best.

3. The height requirements of the curtain
Mainly consider the viewing height and the height from the ground. The horizontal angle of the human eye looking up at the screen is generally controlled within 15°. The average person sitting on the sofa is about 1050mm off the ground and the angle is 15°. The height from the center of the curtain, that is, the height of the curtain viewed by the human eye.

Generally, it is through: the height of the floor - the distance from the center of the curtain to the top surface - half of the height of the curtain, and this formula gives the height of the curtain from the ground.
