Getting Viewing Distances Right for Every Audience

Ensuring optimal viewing distances is crucial for delivering an exceptional visual experience. If all viewers can’t comfortably read or engage with the content, the display fails its purpose – especially in professional and learning environments.

The DISCAS Standard – A Scientific Approach

The Display Image Size for 2D Content in Audiovisual Systems (DISCAS) standard provides precise metrics to guarantee that all viewers, including those at the back, have an equitable viewing experience.

However, practical constraints – such as ceiling height limitations – can sometimes prevent installing the ideal screen size specified by DISCAS. In such cases, DISCAS provides practical guidance on content adjustments, including minimum font size recommendations, to maintain readability across different seating positions.


Key Considerations for Optimal Viewing Distances

  • Screen Size Matters – The screen must be large enough so even the furthest viewers can comfortably engage with the content.
  • Content Design Adjustments – Font sizes, contrast levels, and visual elements should be optimised to maintain clarity at all viewing distances.
