Throw Ratio

What is Throw Ratio?

Throw ratio is a term used in the context of projectors to describe the distance between the projector and the screen in relation to the size of the projected image.

It is expressed as a ratio, such as 1.5:1, and represents the distance from the projector to the screen divided by the width of the projected image. For example, a projector with a throw ratio of 1.5:1 would need to be placed 1.5 feet away from the screen for every 1 foot of screen width. If the screen width is 10 feet, the projector would need to be placed 15 feet away. There are three types of throw ratios: short-throw, standard-throw, and long-throw. Short-throw projectors have a throw ratio of less than 1.0:1, meaning they can produce a large image from a very short distance. Standard-throw projectors have a throw ratio of between 1.2:1 to 2.0:1, while long-throw projectors have a throw ratio of greater than 2.0:1. When choosing a projector, it is important to consider the throw ratio in relation to the size of the room and the intended use of the projector. A short-throw projector may be more appropriate for small rooms or interactive displays, while a long-throw projector may be necessary for large venues or outdoor events. Overall, throw ratio is an important factor to consider when choosing a projector, as it can affect the size and quality of the projected image. It is important to choose a projector with a throw ratio that is appropriate for your specific use case and environment.
