Calculating the optimal throw ratio for your set upĮ.g., If you want to project an image that is 20ft wide while placing your projector 30ft away, you will need a projector with a throw ratio of 1.5 (30ft / 20ft).(Image Width = Throw Distance / Throw Ratio) The width of the image a projector will produce given its throw ratio & throw distance.(Throw Distance = Throw Ratio x Image Width) Where to place a projector given its throw ratio & your projected image size.(Throw Ratio = Throw Distance / Image Width) The ideal throw ratio given the setup of your experience.With the throw ratio equation, you can determine: Using the throw ratio equation and its variations is essential when selecting the right projector for your experience - it’s important to consider the positioning of your projector and the size of the image you’d like to project (or the size of the scene you’d like to cover). Sometimes, the throw ratio is measured in terms of throw distance to image height (vertical throw ratio) or image diagonal (diagonal throw ratio). Note: Throughout this article, we refer to throw ratio in terms of horizontal throw ratio, in which the throw ratio is described as the throw distance compared to the image width. The smaller the throw ratio, the larger the image a projector will produce at a shorter throw distance. 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. Throw Ratio tells us what image size we can project from a certain distance away. Throw ratio is the relation between the throw distance (the distance between the projector's lens and the projected image) and the width of the projected image: Throw Ratio = Throw Distance / Image Width The distance between the projector's lens and the projected image. The relation between the throw distance and the image width tells us what image size we can project from a certain distance away. LF1: Your projector’s throw ratio should be in the range of 0.85-1.8 Glossary LFC Kit: Your projector's throw ratio should be in the range of 0.50-2.0 Don't wait to start enjoying your new projection setup or other gear and get it while the getting is good and before the shelves are bare during the Black Friday shopping bonanza.Lightform devices work with most projectors.
