Short throw vs ultra-short-throw vs standard
The three projector throw types explained by throw ratio — UST (below 0.4), short throw (0.4–1.0) and standard (1.0–2.0) — with where each sits and what it suits.
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.
Throw type is just a band of throw ratios. UST projectors are laser TVs that live on a cabinet below the screen and need a special CLR screen. Standard projectors mount on the ceiling or back wall and are the cheapest. Short throw sits between the two — handy for tight rooms without going UST.
