![]() Note that the resulting image will be smaller than nominal in all three dimensions (top width, bottom width, and height). Hit "calculate" to see the amount of tilt from horizontal necessary to raise the image, and the resulting image distortion.It actually doesn't matter which units you use as long as you're consistent. Also, enter the amount by which you wish to raise the image. These numbers can be determined from projector calculators such as this web-based one at projector central or this Mitsubishi-specific one (requires installation). ![]() In the input section, enter the lens drop, image drop, image height, and throw distance as shown in the diagram, assuming no tilt.These can be important considerations, particularly for rooms with low ceilings and high offset projectors. ![]() It also determines the resulting keystone image distortion. This Javascript calculator determines the amount of tilt or pitch needed to raise a projected image a given height. If you plan to have a lot of light in the room, you should consider increasing the brightness even more.Tilt and Keystone Distortion Calculator for Front Projection Home Theater Tilt and Keystone Distortion Calculator for Projectors
