UST Projector Screen Size Guide: Choose the Diagonal That Fits the Whole System

The correct screen size is the largest size your room, projector and viewing position can support comfortably — not simply the largest option in the product menu.

Measure in the right order

  1. Measure available wall width and height.
  2. Measure the maximum floor-case width your furniture layout can accept.
  3. Check your projector’s placement chart for the target diagonal.
  4. Confirm the projector can deliver enough brightness at that image area.
  5. Check seating distance and sightlines.
  6. Reserve space for speakers and cable access.

Diagonal is not case width

A 100-inch 16:9 image is about 87 inches wide, but a floor-rising case needs extra width for the roller, side structure and housing. Buying from image diagonal alone is a common way to discover that a screen blocks a doorway or overhangs a media unit.

Allow alignment tolerance

UST geometry is unforgiving. Leave enough furniture and wall tolerance to shift the projector and screen slightly during setup. Designing a layout with zero spare millimeters creates unnecessary alignment stress.

Use the commercial page last

Once you know the diagonal, case clearance and control requirements, check the current PET Crystal Classic offer for the matching size and regional configuration. That order avoids letting a sale price choose a screen that does not fit.
