FAQ
How far should a projector be for a 100 inch screen?
A standard-throw projector needs about 8.7–14.5 ft from a 100" screen. Check your projector’s throw ratio — multiply it by the 87.2" screen width to get the exact distance.
Can I use a short-throw projector for a 100" screen?
Yes — a short-throw model sits just 2.9–5.8 ft away, and an ultra-short-throw projector only 1.31–2.54 ft (basically against the wall).
What size room do I need?
For standard throw, allow at least 14.5 ft between the projector and the wall. Tight room? Pick a short- or ultra-short-throw projector.
