Projector screen sizes can be confusing until the meanings of the numbers are clarified. Usually screens are advertised as a single number, such as 50 inches of 60 inches, which can be quite surprising that a rectangle can be measured in just one dimension. This is especially true when a buyer needs to make sure the screen will fit in a defined area. Because the 16:9 aspect ratio is used in widescreen projections, most projectors use this ratio, so a few simple calculations can determine screen size and dimensions.
Instructions
Calculating the Size of a Projector Screen
1. The size of a projector screen is measured along the diagonal from the lower right hand corner to the upper left hand corner. This is the size that will be advertised.
2. Assuming the projector screen uses the standard 16:9 ratio, to determine the height, multiply the diagonal by 0.495. For example, if the screen size was 50 inches, multiply 50 * 0.495 and the height would be 24.75 inches.
3. Assuming the projector screen uses the standard 16:9 ratio, to determine the width, multiply the diagonal by 0.87. For example, if the screen size was 50 inches, multiply 50 * 0.87 and the height would be 43.5 inches.
