The formula to calculate the Viewing Angle is:
\[ VA = 2 \arctan\left(\frac{SW / 2}{D}\right) \]
Where:
Let's say the screen width is 2 meters and the distance to the screen is 3 meters. The viewing angle would be calculated as follows:
\[ VA = 2 \arctan\left(\frac{2 / 2}{3}\right) \approx 36.87 \text{ degrees} \]
So, the viewing angle is approximately 36.87 degrees.
The viewing angle is the angle subtended by the width of the screen at the viewer’s eye. It is an important factor in determining the optimal distance from a screen for the best viewing experience. A larger viewing angle generally means a more immersive experience, but if the angle is too large, it can cause discomfort and require excessive head movement.
