## What is a good throw ratio for projectors?

Among all existing projectors, a throw ratio around 1.13:1 is the most common design that has the lens in the front of the projector. These designs can require distances as short as 8.2ft to project a 100-inch screen, which is the most common throw distance setup in limited space or small apartments.

How far should a projector be from a 120 screen?

147 to 160 inches
Projection Distance

Screen or image size Projection distance (1) Minimum to Maximum Screw hole number (2)
80 inches (203 cm) 97 to 106 inches (248 to 270 cm) 4
100 inches (254 cm) 122 to 133 inches (310 to 338 cm) 3

150 inches (381 cm) 184 to 200 inches (467 to 509 cm) 1

How far should I put my projector from the screen?

You can calculate this position by multiplying the throw distance number (in this example, 1.3) by the horizontal length of your screen (not diagonal). For example, if your screen is 87” wide and the throw distance of your projector is 1.3, the projector should be 113” (87×1. 3=113”) from the screen.

## Is a 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 away should a projector be from a 100 inch screen?

around 10.5ft
How Far Should a Projector Be From a 100-Inch Screen? Ideally, you should use your projector’s manual or manufacturer’s website to calculate the best distance from the screen for your particular projector.

How far should a projector be from a 135 inch screen?

## How far back should you sit from a 100 inch screen?

### At what distance should projector placed?

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.
