Definition of Throw Distance
Throw distance is the distance required between the projector lens and the screen to display a specific size image. There are three throw distance categories for video projectors, including:
- Standard Throw (or Long Throw)
- Usually requires 6 or more feet to project an 80-inch image
- Short Throw
- Usually needs about 4-5 feet to project a 100-inch image
- Ultra Short Throw
- Can display a 100-inch image at a distance of about 2 feet or less
Calculate Your Throw Distance
Use the equation below to calculate how close you can place your projector:
