Understand your user needs and content
Can you see me at the back?
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 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.
See our Tools & Resources section for more helpful tools and tips.
Delivering the right display size and content legibility is essential for every AV project. Use the DISCAS standard to guarantee clarity, compliance, and client satisfaction.
