What this tool does
Calculate projector throw distance from technical measurements. Check the manufacturer's lens range, offsets and installation constraints.
How to use the Projector Throw Distance Calculator
- Enter or select projected image width in in.
- Enter or select throw ratio.
- Read the calculated result; change any measurement to compare alternatives.
Formula
throw distance=image width×throw ratio
- width
- Projected image width (in, before metric conversion)
- ratio
- Throw ratio
Check the manufacturer's lens range, offsets and installation constraints.
Worked example
For projector throw distance calculator, the following measurements illustrate the exact method: Projected image width: 100; Throw ratio: 1.5.
Inputs
- Projected image width100 in
- Throw ratio1.5
Result
- Lens-to-screen distance150 in
Results explained
- Lens-to-screen distance
- Lens-to-screen distance from the formula above, expressed in in before metric conversion. Check the manufacturer's lens range, offsets and installation constraints.
