What is throw ratio in projectors?
The throw ratio in projectors refers to the relationship between the distance of the projector from the screen and the width of the projected image. It is usually expressed as a ratio, such as 1.5:1 or 2.0:1, with the first number representing the distance and the second number representing the width of the image. Understanding the throw ratio is crucial in selecting the right projector for a particular room or application.
A projector with a lower throw ratio can produce a larger image from a shorter distance, making it ideal for smaller rooms or applications where space is limited. On the other hand, a projector with a higher throw ratio requires a longer distance to produce the same image size, making it more suitable for larger rooms or applications where the projector can be placed farther away from the screen.
How is throw ratio calculated?
The throw ratio is calculated by dividing the distance of the projector from the screen by the width of the projected image.
