3 to 4 meters, the best projection distance for projection is 3 to 4 meters, and the projection distance will change relatively according to the projection ratio. The ratio of most projectors is 1:2 to 1, and the best projection distance is 3 to 4 meters.
The best projection distance for projection is 3-4 meters. The projection distance needs to be adjusted according to the projection ratio. The projection ratio of the projector is mainly 1.2:1, 0.8:1 and 0.235:1, etc. Among them, 1.2:1 is the most common. The best throw distance is between 3 and 4 meters. A projector with a 1.2:1 throw ratio can project a 112.54-inch screen at a distance of three meters. A projector with a throw ratio of 0.8:1 can reach a 100-inch projection screen within a range of 2 meters.
The projection distance can refer to the following calculation methods: Minimum projection distance (meters) = minimum focal length (meters) x screen size (inches) ÷ LCD screen size (inches), maximum projection distance (meters) = maximum focal length (meters) x picture size (inch) ÷ LCD panel size (inch). Or you can use our projector calculator to get the number with no messing.
