Guides for this projector
Short throw vs ultra-short-throw vs standard
The three types are set by throw ratio: ultra-short-throw (UST) is below 0.4 and sits inches from the wall; short throw is 0.4–1.0 and sits a few feet back; standard (long) throw is roughly 1.0–2.0 and sits across the room. For a 100-inch screen that is under 3 ft, about 3–7 ft, and 7–15 ft respectively.
GuidesHow to calculate projector throw distance
Throw distance = image width × throw ratio. First convert the screen diagonal to width (for 16:9, width = diagonal × 0.872), then multiply by the projector's throw ratio. For a 100-inch screen (87 inches wide) and a 1.5 throw ratio: 87 × 1.5 = 131 inches, about 11 feet.
GuidesProjector vs TV
A projector wins on sheer size and cost-per-inch — 100 to 200 inches for the price of a much smaller TV — but needs controlled light or an ALR screen. A TV wins on brightness, convenience and lifespan. For movie nights on a big screen, choose a projector; for all-day bright-room viewing, choose a TV.
