ProjectorCalc is a program for professional lighting technicians and projectionists. Its primary purpose is to determine the size of a projected image given various information about the projector and it's location.
ProjectorCalc allows users to enter details for a projector and its location in relation to a projection surface.
ProjectorCalc will calculate image width, image height, diagonal length, brightness in Nits, total projected area, and how many pixels per inch the projected image will be.
Additionally, ProjectorCalc can give you an estimate of how much keystone distortion will occur by calculating the length of each side of the distorted image.
