Bright-room screen guide
Continue to the next decision in the screen-selection process.
Sports is one of the clearest reasons to care about ambient-light performance: many games happen during the day, and groups usually do not want to sit in a pitch-black room.

Movie nights can happen after dark. Sports viewing often means windows, food, people moving around and lights left on. That makes perceived contrast in ambient light more important than it might be in a dedicated cinema.
For groups, bigger can be compelling, but each size step raises the light-output requirement. A 120-inch screen is roughly 44% larger in area than a 100-inch screen; a 130-inch screen is roughly 69% larger. That extra area can be fantastic for sports if your projector has the output to fill it.
The featured screen is a standard/long-throw ALR design with a published 0.8 gain, 170° viewing angle and 100–130 inch sizes. The manufacturer recommends 2,000 ANSI lumens or more. Those are relevant specifications for social, mixed-light viewing—especially when you already own a conventional long-throw projector.
