What is a good throw distance?
So for example, the most common projector throw ratio is 2.0. This means that for each foot of image width, the projector needs to be 2 feet away or D/W = 2/1 = 2.0. So if I’m using a projector with a throw ratio of 2.0 and I have an image width of 5 feet, then my throw distance must be 10 feet.
How do you calculate throw distance and throw ratio?
Throw Ratio = Throw Distance / Image Width Throw Ratio tells us what image size we can project from a certain distance away. For instance, a throw ratio of 1.5 indicates that for every 1 foot of image width, the throw distance must be 1.5 feet.
How far should I sit from a 120 inch screen?
With one caveat..which we will get to in a bit. If your family likes being near the center of the theater, then choose a screen size which has about 10 inches of diagonal for each foot of viewing distance. That’s about 120-inch diagonal for a 12 foot viewing distance.
Is higher throw ratio better?
Throw Ratio tells us what image size we can project from a certain distance away. For instance, a throw ratio of 1.5 indicates that for every 1 foot of image width, the throw distance must be 1.5 feet. The smaller the throw ratio, the larger the image a projector will produce at a shorter throw distance.
How far can a projector throw?
Short-throw projection generally refers to a distance between 3 to 8 feet away from projector to screen. Ultra-Short Throw: Virtually eliminates shadows and eye glare, this type of throw is seen from projectors installed on the wall, the ceiling nearer to a wall, or a table projecting downwards.
How far should you sit from a 110 inch screen?
around 9 feet
So, if the width of your TV is 55 inches, the minimum viewing distance should be 110 inches or around 9 feet, while the maximum distance should be 275 inches or no more than 23 feet. In short, the first row of recliners should be placed at least 9 feet away from the screen.
How far should you sit from a 135 inch screen?
The old rule of thumb for 1080p is to sit right around 1.5 times your diagonal image size. Which in your case for a 135” screen would be about 16/17 feet back so you’re pretty much right on the money.
What is maximum throw distance for a projector?
As most video screens today are a 16:9 ratio, your magic number is 0.872. Multiply your diagonal screen width by that number, then multiply by the throw ratio: 10′ x 0.872 x 1.35 = 11.7′ minimum, 10′ x 0.872 x 1.64 = 14.3′ maximum.
