What is minimum throw distance for a projector?
What is minimum throw distance for a projector?
Short throw projectors need to be between 5 and 10 feet away from the screen, depending on how large of an image you want. Short throw projectors have a throw ratio between . 4 and 1.
What is the optimal distance for a projector?
The absolute “best” distance between the projector screen and room seating is hard to calculate. Instead, a general rule is that seats should be located a distance that is no less than double the width of the projected image, and no more than five times the width of the image (the furthest seat from the screen.)
How far does projector have to be from 120 screen?
Projection Distance
| Screen or image size | Projection distance (1) Minimum to Maximum | Screw hole number (2) |
|---|---|---|
| 80 inches (203 cm) | 110 to 121 inches (281 to 306 cm) | 4 |
| 100 inches (254 cm) | 138 to 151 inches (351 to 383 cm) | 3 |
| 120 inches (305 cm) | 166 to 181 inches (422 to 461 inches) | 2 |
| 150 inches (381 cm) | 208 to 227 inches (529 to 577 cm) | 1 |
How is throw distance calculated?
D/W=T (distance divided by width equals throw) or TxW=D (throw multiplied by width equals distance).
How do you calculate throw distance?
How do you calculate projector screen size and distance?
If you know where you’ll be putting your projector, measure the distance between the lens and the wall, then multiply this by the throw ratio. This will tell you the width of the projected image. Use the aspect ratio to get the height, then use the Pythagorean Theorem to find the screen size.
Is ultra short throw better?
Ultra short throw projectors aren’t necessarily better than traditional projectors. Still, they make it almost impossible for anyone to walk in front of the projected image, and they tend to offer fewer shadows and glare compared to more typical designs.
