A 145 × 145 cm tripod projector screen is a practical choice when you need a neat, self-contained screen that can move between rooms quickly. With a 1:1 square format and a viewing area of roughly 145 cm by 145 cm, it works well for a wide range of content, including PowerPoint, spreadsheets, training material and basic video, without locking you into a single aspect ratio. Square-format screens remain popular in education and business because they can comfortably show both 4:3 content and letterboxed widescreen material.
This type of screen typically uses a matte white surface with black backing, around 1.0 gain and a wide viewing angle, often around 160°, so images stay bright and uniform across the surface without hot spots. The black backing helps block light from behind, improving contrast in rooms where you cannot fully control ambient light. The result is a clean, readable picture for small meeting rooms, classrooms, briefings and breakout spaces.
