How do you calculate projector screen size and distance?
If you know where you’ll be putting your projector, measure the distance between the lens and the wall, then multiply this by the throw ratio. This will tell you the width of the projected image. Use the aspect ratio to get the height, then use the Pythagorean Theorem to find the screen size.

How far to sit from a projector screen?
The size of the image also determines how far you should sit from the screen for optimum viewing. For an HD-capable projector, the general rule of thumb for viewing distance is 1-1/2 times the screen diagonal — so if your screen’s diagonal measurement is 96″ (8 feet), you would want to sit about 12 feet from the screen.
What is the distance from a projector to the screen?
Throw distance is the distance from the screen to the projector. 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.
How to calculate projector distance?
Think of the Projector’s throw ratio (R) as the π of home cinemas. So, beginning from this formula, we can derive the two formulas for calculating the distance from the screen and the width of the screen, respectively: D = Rt * W
What is the optimal distance for a projector?
So, in this case, the optimal distance to place your projector would be anywhere from 12 to 18 feet (3.7 to 5.5 meters). After you’ve managed to decide in the distance, it’s time to manage the cables.
