Using Throw Ratio
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). With the throw ratio equation, you can determine:
1. The ideal throw ratio given the setup of your experience
TR = TD / IW
(Throw Ratio = Throw Distance / Image Width)
2. Where to place a projector given its throw ratio & your projected image size
TD = TR x IW
(Throw Distance = Throw Ratio x Image Width)
3. The width of the image a projector will produce given its throw ratio & throw distance
IW = TD / TR
(Image Width = TD / TR)
