The right screen size is determined based on the actual viewing distance and not just the size of the room, but the most frequently asked question has always been, “What is the right screen size for my room?” This Leaders Center article will provide a practical guide based on international standards on the right screen size for rooms and lounges.

How to measure screen size
Screen size is measured in inches (Inch) and is calculated by the diagonal from corner to corner, with approximate examples as follows to understand the measurement right on the wall:

- Screen size = distance ÷ 2 (visual comfort)
