Projector Screens and Stands

Size, aspect ratio and viewing distance

Screen size is quoted as a diagonal, but the shape matters just as much. A 100-inch 16:9 screen is about 87 inches wide and 49 inches tall, whereas a 4:3 screen of the same diagonal is taller and narrower. Match the screen's ratio to your projector's native ratio, usually 16:9 or 16:10, so the picture fills it without bars or cropping. A common guide is to sit about one and a half to two screen widths away, and a larger screen needs a projector bright enough to fill it.

Fixed frame, pull-down, tripod or inflatable?

Fixed-frame screens hold the fabric flat and give the cleanest image, which suits a permanent room. Manual pull-down screens roll away when not needed, but fabric can ripple. Tripod and floor-standing models set up quickly for travelling presentations, and inflatable screens suit outdoor movie nights, though they need a blower and shelter from wind. Surface matters as well: matte white spreads light widely, while grey or ambient-light-rejecting fabrics improve contrast when the room is not dark, often at the cost of narrower viewing angles.

Questions about Projector Screens and Stands

What does screen gain mean?

Gain describes how much light the surface reflects compared with a reference white. A gain near 1.0 spreads light evenly with wide viewing angles, while higher values brighten the centre but narrow the view and can show hot spots.

Can I just use a white wall?

For casual use, a smooth, matte, light-coloured wall works. A real screen gives flatter, more even brightness and better contrast, and fixed or tensioned models avoid ripples and texture.

How big a screen should I get for my room?

Base it on viewing distance and projector brightness. A larger picture looks dimmer, so dark rooms handle big screens better. Measure the wall space, allow room for borders, and check that the throw distance fits the room.
