What is the best throw distance for a projector?
Guide to Buying Short Throw and Ultra Short Throw Projectors
| Projector Type | Throw Ratio | Distance From Screen |
|---|---|---|
| Regular Projector | 1.5:1 + | 7.5 feet |
| Short Throw Projector | 0.38:1 – 1.4:1 | 3 feet |
| Ultra Short Throw Projector | 0.37:1 or less | 1.4 feet |
How do you measure projector throw distance?
For any given projector, the width of the image (W) relative to the throw distance (D) is know as the throw ratio D/W or distance over width. 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.
How do you calculate throw distance?
Specifically, the throw ratio. This ratio tells us what size of image we can get from a certain distance away, and it can be calculated two different ways. D/W=T (distance divided by width equals throw) or TxW=D (throw multiplied by width equals distance).
What does projected distance mean?
The distance at which you place the projector from the screen determines the approximate size of the image. The image size increases the farther the projector is from the screen, but can vary depending on the zoom factor, aspect ratio, and other settings.
How far does a projector have to be from a 100 screen?
Projection Distance
| Screen or image size (1) | Projection distance (2) Wide to Tele |
|---|---|
| 60 inches (152.4 cm) | 69 to 113 inches (176 to 286 cm) |
| 80 inches (203.2 cm) | 93 to 150 inches (235 to 382 cm) |
| 100 inches (254 cm) | 116 to 188 inches (295 to 478 cm) |
| 120 inches (304.8 cm) | 139 to 226 inches (354 to 575 cm) |
How far should you sit from a 100-inch projector screen?
Using that calculation, a 100-inch projector screen requires an optimal viewing distance of 119 inches or 3m from the screen. This formula is the generally accepted guideline for judging the optimum distance between the screen and your seating area.
How do I know what projector lens to buy?
Divide the throw distance, from the front of the projector lens to the screen in inches, by the width of the screen in inches. Therefore, you would look for a lens that has a throw-to-width ratio of 1.25:1, (10′ ÷ 8′):1. 2. If your screen width varies, select a lens that offers a Throw to Width range.
How far away does an outdoor projector need to be?
But how do we find out what the ratio of our projector is? Simply consult your projector’s specs. So, in this case, the optimal distance to place your projector would be anywhere from 12 to 18 feet (3.7 to 5.5 meters). After you’ve managed to decide in the distance, it’s time to manage the cables.
Is short throw projector better?
Short throw can create far greater images at much shorter distances, making them ideally suited to those who only have a small area in which to house their projector, so schools and bedrooms are ideal for these type of projectors. These projectors can, for example, create an image of 100 feet from just 15 feet away.
How wide is a 120 inch projector screen?
120-inch Diagonal, 16:9 Aspect Ratio. View Size: 58.8″ H x 104.6 W. Overall Size: 63.5″ H x 109.3″ W.
How far does a projector have to be from a 200 inch screen?
Projection Distance
| Screen or image size (1) | Projection distance (2) Wide to Tele |
|---|---|
| 100 inches (254 cm) | 116 to 188 inches (295 to 478 cm) |
| 120 inches (304.8 cm) | 139 to 226 inches (354 to 575 cm) |
| 150 inches (381 cm) | 174 to 283 inches (443 to 719 cm) |
| 200 inches (508 cm) | 233 to 378 inches (591 to 959 cm) |
What does throw distance on a projector mean?
Throw Distance and Positioning. Therefore, you will need to consider the throw distance and the projector features that will give you placement flexibility. A projector’s throw distance is the distance between the projector and the image on the screen (i.e., the distance that the image is “thrown”).
What do you mean by ultra short throw projection?
Ultra-short throw projection refers to a distance between 0 to 4 feet away from projector to screen.
What’s the difference between throw ratio and throw distance?
Throw distance is specifically the distance between the projector lens and the screen, and when you see it in a product description it means the distance that the projector in question is ideally suited to. Throw ratio on the other hand is the relationship between the throw distance and the size of the screen – they are proportional to each other.
What is the throw ratio of a screen?
A common throw ratio is 2:1 which means that for every foot of image width, the projector needs to be 2 feet away from the screen. For every 2′ you move the projector away, the image will get one foot wider. So if your 2:1 projector is 12′ away, you’ll end up with a screen width of 6′.
