![]() On a 10-foot wide 2.35 screen, a 4:3 picture will be 24 square feet. To illustrate, compare the following images of the 1.85 format scene from Chicago on a 2.35 screen, and on a 16:9 screen of the same width: That is a much bigger 16:9 image-almost double the square footage. Conversely, if you installed a 16:9 screen that was 10 feet wide, the total square footage of your 16:9 image would be 10 x 5.62, or 56.2 square feet. The total square footage of that 16:9 image will be 4.25 x 7.56 = 32.1 sq. A film in 2.35 will take up the entire 10 foot screen width, but a 16:9 image will be only 7.56 feet wide. What will vary is the width of the image. Now, on this ten-foot wide 2.35 format screen, every image you project will be the same height, which is 4.25 feet. ![]() Since this room size does not limit the height of the screen, the 2.35 format actually turns out to be the smallest screen you can install from a total square footage perspective. And if you wanted to go 4:3, it would be 10 feet wide and 7.5 feet tall. If you opt for a 16:9 screen, it will be 10 feet wide and 5.62 feet high. If you go with a 2.35 screen, it will be 10 feet wide and 4.25 feet high. Now, since this room has a 9 foot ceiling, the height of your screen can be pretty much anything you want. Practically speaking, this wall size limits you to a maximum screen width of about 10 feet. Let's also assume you want to leave two feet to either side of the screen for speaker placement and aesthetic clearance from the walls. Let's assume for example that the wall you are projecting onto is 14 feet wide and 9 feet high. Why? In the vast majority of home theater situations, the room dimensions place a practical limit on the maximum width of the screen before placing any limitation on its height. In general, the most significant penalty to be paid by going with a 2.35 set up is that your 16:9 and 4:3 images will be much smaller than they would be if you used a 16:9 screen. So they want to see them full frame, without black bars above and below the image, which is what you get if you display them on a 16:9 screen. In addition, many people think that 2.35 films are the most important and/or most common type of video material they watch. ![]() ![]() There is a certain WOW factor involved with this, and many people find that it adds excitement to the home theater experience. If standard 16:9 is being displayed, and suddenly the curtains retract revealing a wider screen, and then a 2.35 format movie appears on that screen, it looks even bigger and more impressive than the conventional 16:9 image. The reason some people like the 2.35 format is that it can have a more dramatic appearance compared to standard 16:9 widescreen. The following is a scene from Gone With The Wind, which was done in 4:3, on a 2.35 screen: It can be positioned in the center of the 2.35 screen, with larger pillar-boxing on either side. There is also plenty of 4:3 format material still being watched today as well. Here is what a scene from Chicago looks like on a 2.35 format screen: For example, the movie Chicago was done in 1.85. When this type of material is displayed on a 2.35 screen, you get black vertical bars, or columns, on each side the image, commonly referred to as pillar-boxing. In addition, there are a few films done in 1.78, and many more are done in 1.85, which is so close to 1.78 that you usually don't notice the difference. Meanwhile, all regular HDTV programming is in 16:9 format, otherwise known as 1.78 because 16 divided by 9 is 1.78. As an example, The Fifth Element was done in 2.35, and if you project it onto a 2.35 screen it would look like this: The big advantage is that you can see movies that are made in this format full frame, without any black bars above or below the picture. The idea is to install a screen with a 2.35:1 aspect ratio, or 2.35 units wide for every one unit of height. If you are about to install a new home theater, a fundamental question to ask would be, "Is the 2.35 format right for me, or should I stay with 16:9?" Let's examine the issues and see what's right for you.įirst, let's be clear about what we are talking about. The most popular of the alternative formats is 2.35:1 since many motion pictures are filmed in this aspect ratio. Just when everyone has gotten used to the concept of converting from plain ole 4:3 television to widescreen 16:9 video systems, a new format option is popping up-some people are going with even wider screen formats for their home theaters.
