Screen diagonal is not screen width
The table shows the visible 16:9 image, rounded to one decimal inch. The outer frame and mounting clearance depend on the product. A 120-inch screen is about 104.6 inches wide, not 120 inches wide.

YOUR HOME. THE MAIN EVENT.
A bigger screen is not automatically better. The ideal projection size depends on how far you sit, how much room you have, the projector output and the type of content you watch.

Home Theatre Screen Size: 16:9 Dimensions & Distance
Screen size is measured diagonally, but the wall must accommodate the image width, image height and frame. Match screen size to the main seat, projector output, room lighting and installation clearances.
Choose the seat and image together
Measure from your eyes to the image surface. The calculator shows horizontal viewing angle; use it to compare options, then test a taped outline for comfort. Content, eyesight and preference matter.
A larger image spreads the same light over more area. Ask for a brightness assessment using the intended projector, screen material, lamp/laser mode and actual ambient light.
Check projection geometry before ordering
Throw ratio equals lens-to-screen distance divided by image width in the same unit. A 120-inch 16:9 image is about 8.72 ft wide; a 1.50 ratio gives approximately 13.1 ft from lens to screen.
This is not the distance from the back of the cabinet. Ultra-short-throw projectors need model-specific cabinet and screen-height drawings.
| Diagonal | 16:9 image width | 16:9 image height |
|---|---|---|
| 100 in | 87.2 in | 49.0 in |
| 120 in | 104.6 in | 58.8 in |
| 133 in | 115.9 in | 65.2 in |
| 150 in | 130.7 in | 73.5 in |
PLAN WITH REAL DIMENSIONS
Screen & throw calculator
16:9 image geometry. Enter lens-to-screen throw ratio from your exact projector manual; cabinet distance is different for UST models.
Geometry is a planning aid, not a compatibility or comfort guarantee. Add frame clearance, wall treatment depth, ventilation and the manufacturer’s mounting offsets. No data is submitted.

Guide
What determines screen size?
Viewing distance
Your main seating position should be considered before selecting the screen diagonal or aspect ratio.
Projector brightness
As screen size increases, the same projector light is spread across a larger area.
Room width
Speaker placement, side-wall treatment and sightlines should remain practical around the screen.
Content
Movies, sports and gaming can have different preferences for size and aspect ratio.
Guide
Screen size should be designed with audio
The centre speaker, left and right speakers and acoustic treatment all need to work around the screen. This is one reason screen selection should happen before final installation rather than as an afterthought.
