Know what 100-inch really means
A 100-inch 16:9 image is about 87 inches (2.21 m) wide and 49 inches (1.25 m) high before adding the frame. Always use the manufacturer’s full frame dimensions for mounting.
Leave room for the UST cabinet
The projector does not sit flush against the wall. Its exact throw ratio determines how far the chassis and lens must sit from the screen. Cabinet depth, center-speaker location and screen height all interact.
Check seating width, not just distance
Viewing angle is relevant across the sofa. A 160° listed screen gives more theoretical off-axis freedom than a narrow Fresnel design, though real perceived brightness and color still vary with angle and room light.
When to move beyond 100 inches
Move to 120 inches only if wall width, seating distance, projector brightness and mounting height still work. A larger diagonal increases immersion but also increases image area, reducing luminance if projector output stays the same.
Use PET Crystal Classic as a reference point.
It is a 0.6-gain, 160° listed-viewing-angle, 85% ALR fixed-frame UST screen.

How wide is a 100-inch 16:9 image?
Approximately 87 inches or 2.21 meters wide, before the screen frame.
Does a 100-inch screen fit every UST projector?
No. Confirm the projector’s supported image size and throw geometry for a 100-inch image.
