Projector screen height: 80 ” * 0.57 = 45. Projector screen diagonal: 80 ” / 0.87 = 92 ” Width of a home theater projection screen: 80″ Projector screen diagonal: 100″ / 0.87 = 115″ This little tool, helps you calculate the width, height or diagonal of a (TV)screen, for a given screen ratio. Width of a home theater projector screen: 100″ Projector screen height: To calculate the projection screen height, from the known width, multiply the width by 0.57 Examples: Projector screen diagonal: To calculate the projector screen diagonal from the known width, divide the width by 0.87 If you know projection screen width, and need to calculate diagonal size and height of the screen: This means that for each foot of image width, the projector needs to be 2 feet away or D/W 2/1 2.0. So for example, the most common projector throw ratio is 2.0. Projector screen width: 0.87 x 110″ = 95.7″ For any given projector, the width of the image (W) relative to the throw distance (D) is know as the throw ratio D/W or distance over width. The TV dimensions are given for a 16:9 aspect ratio. Projector screen width: 0.87 x 100″ = 87 inchesĭiagonal Size of a home theater projection screen: 110″ This table can be used to determine the dimensions (height and width) for e.g. You can use either an aspect ratio, or, if you do not know your screens aspect ratio, you can input your screens resolution. Projector screen height: 0.495 x 100″ = 49.5 inches Therefore, you could alternately describe the 4:3 aspect ratio as 1.33:1, meaning that for every 1.33 units in width, there is 1 unit in height. This calculator will convert an aspect ratio and horizontal FOV to a vertical FOV, useful for setting your favorite horizontal FOV in a game that uses vertical FOV. Projector Screen Width: The width of the projector screen is approximately 87% of the projector screen’s diagonal, so multiply the diagonal measurement by approximately 0.87.ĭiagonal Size of a home theater projector screen: 100″ In the silent film era, movies were shot on various-sized negatives, but the. (In other words the height of the screen is just a bit less than 50% of the diagonal. The history of aspect ratio dates back to the early days of film and television. Projector Screen Height: To calculate the projector screen height, multiply the diagonal by approximately 0.495. If you know your projector screen’s diagonal size: Simply put, a 16:9 projection screen is 1.78 times as wide as it is high. It wasnt until the 1990s and 2000s that the widescreen 16:9 ratio became more popular as a video format. so they didnt need to be converted for TV release. These calculations are for standard 16:9 aspect ratio screens (HDTV shape), which are used by the vast majority of home theater users, as the vast marjority of home theater projectors are 16:9 native aspect ratio. The 4:3 aspect ratio is commonly known as the fullscreen aspect ratio. They are slightly rounded for your convenience.Īll calculations are based on the screen area, and do not include the borders or frame. Here are your basic formulas for calculating projector screen dimensions.
