What should be the maximum angle above the standard line of sight for display positioning?

When considering the maximum angle above the standard line of sight for display positioning, 30 degrees is widely recommended as it strikes a balance between visibility and ergonomic comfort. This angle ensures that viewers can engage with the display without straining their necks or eyes, which is crucial for maintaining comfort during prolonged use.

Positioning displays too high can lead to discomfort, as viewers would need to tilt their heads upwards, which can cause fatigue over time. The 30-degree guideline allows for a practical compromise, accommodating various viewer heights and seating arrangements while also considering the natural line of sight when seated.

While some other angles, such as 25 degrees, are also considered acceptable, 30 degrees serves as a more universally applicable standard that most designs aim for to ensure optimal visibility and user comfort. Angles greater than this may lead to diminishing returns in effective viewing and an increase in the risk of physical discomfort.
