120-inch ALR Projector Screen Guide for UST Setups
A 120-inch image feels dramatically larger than a 100-inch screen, but the jump is not just visual. It changes furniture width, projector placement, delivery logistics and how much of the room the screen owns.
How big is a 120-inch 16:9 screen?
A 120-inch diagonal 16:9 image is approximately 104.6 inches (2.66 m) wide and 58.8 inches (1.49 m) high. The physical housing of a floor-rising screen is wider than the image itself, so never plan furniture from diagonal size alone.
Why 120 inches is a “room decision,” not just a screen decision
At this size, the screen becomes a piece of architecture. You need enough uninterrupted width, the correct vertical height, a UST cabinet or projector platform in the right relationship to the screen, and a realistic viewing distance for the content you watch.
Also plan for delivery. NothingProjector currently lists a 33 kg / 72 lb package weight for its 120-inch Black Series floor-rising model and a package length of roughly 115.7 inches / 294 cm. That is long enough to make stairs, lifts, tight corners and doorways relevant.
Floor-rising makes 120 inches easier to live with
A permanent 120-inch fixed frame can dominate a mixed-use living room. A floor-rising unit changes the trade-off: you accept a large base cabinet and motorized mechanism, but the viewing surface can disappear when not in use.
Measure these before ordering
- The total furniture or floor run available for the screen housing.
- The clear rise height above the housing.
- The projector's required throw distance and image offset for exactly 120 inches.
- Power access on the correct side of the screen. NothingProjector notes that its standard plug position is on the left when facing the screen, with other arrangements requiring coordination.
- Delivery route from the entrance to the final room.
Should you sit farther back?
There is no single perfect seating distance because visual acuity, content type and personal preference differ. The right method is to treat 120 inches as a field-of-view choice. If you are sensitive to seeing individual motion or prefer a more relaxed image, sit farther back; if you want a cinema-like immersive field of view, sit closer.
Before buying, tape the approximate 105-inch image width onto the wall or use painter's tape to mark the corners. Live with the outline for a day or two. That simple test often reveals whether the room can actually carry the scale.
