6 Best Free Projector Calculator Software for Windows

Here is a list of best free projector calculator software for Windows. Using these free software, you can simulate different projector models and calculate various projection related values which help you setup a projector in order to create a screen image. These calculations include number of projectors, projector’s throw distance, projector spacing, lens ratio, lens shift, etc. All of these software create a projection throw distance and screen image diagram for results visualization. You can print the entire diagram with results in these projector calculation software.

All of these projection calculator software contain a variety of projector models which you can simulate. But, remember that each of these software provides projector models only for a specific brand such as Sony, Mitsubishi, Panasonic, Epson, etc. So, you can get a free software from this list to simulate specific projector and perform related calculations. You would need to select a projector model and set screen dimensions in order to simulate image projection and calculate throw distance and other measurements.

Note: These software might not provide exact projection values, but the measurements are close to actual values.

My Favorite Projector Calculator Software for Windows:

All of these projector calculators are good at the simulation of a brand specific projector models. I quite liked PJCalc as it lets you calculate projection values for various types of projectors including CRT, LCD, DLP, and SXRD.
