Given the projector throw ratio and the screenвЂ™s width, the following formula will calculate the throw distance. The minimum and maximum throw ratio should be documented for every projector and is needed to calculate the throw distance. The distance varies by the lens used in the projector and the screenвЂ™s size.

How to Calculate Projector Throw DistanceДЄ projector needs to be installed a specified distance from the screen to allow the image to fill the screen correctly. Use the following chart as a guide for choosing the right screen brightness for your room.Д¬hart showing the optimal screen brightness for various types of rooms 0-15 ft-L You might be wondering how many foot-lamberts you need for a good experience? SMPTE recommends at least 16 foot-lamberts for a dark cinema. The brightness in foot-lamberts is equal to the projector lumens times the screen gain, divided by the area of the screen in square feet. Use the following formula to calculate the brightness of your screen. Some screens also incorporate gain to increase the amount of light reflected to the viewers, increasing the brightness. The projectorвЂ™s luminosity and the size of the screen both contribute to the overall brightness. The screenвЂ™s brightness is typically measured in foot-lamberts or candela per square meter. You can also use an aspect ratio calculator to solve the ratio.ДЄ projector screenвЂ™s brightness is one of the most important factors in a good cinematic experience. Then, divide each dimension by the greatest common factor to get each part of the aspect ratio. Find the greatest common factor between the screenвЂ™s width in pixels or inches and the height in pixels or inches. ItвЂ™s possible to calculate a screenвЂ™s aspect ratio given either the imageвЂ™s resolution or the width and height. We go into much more detail about calculating screen size on our screen size calculator. Screen height = AR h Г— diagonal в€љ(AR w 2 + AR h 2)

The screen width is equal to the aspect ratio width AR w times the screen diagonal divided by the square root of the aspect ratio width AR w squared plus the aspect ratio height AR h squared. Screen width = AR w Г— diagonal в€љ(AR w 2 + AR h 2) Use the formulas below to calculate a screenвЂ™s width and height. You can calculate the size of a projector screen given the diagonal measurement using the aspect ratio and the Pythagorean theorem.

Try our TV size and distance calculator to calculate the optimal viewing distance for a television. The viewing distance d is equal to the screen width w divided by 2, times the tangent of 180 minus the viewing angle Оё divided by 2. Use the following formula to calculate the viewing distance for a given viewing angle. The Society of Motion Picture and Television Engineers (SMPTE) recommends a viewing angle of 30В°. THX recommends a viewing angle of 26В° to 40В°, with a preferred angle of 36В° to 40В° if possible. Contact us and weвЂ™ll answer your questions. To see how much youвЂ™ll accrue without accounting for inflation, change the field to 0. Various standards define the proper viewing angle for viewing content on a projection screen. Use our retirement calculator tool to determine your projected retirement savings. If you cannot use the Retirement Estimator or you want a survivors or disability benefit estimate, please use one of our other benefit calculators.The optimal viewing distance from a screen depends on the screenвЂ™s width.
