What Do You Know About Aspect Ratio
The aspect ratio describes the proportional relationship between its width and its height. It is commonly expressed as two numbers separated by a colon, as in 16:9. The two most common aspect ratio are 4:3, also known as 1.33:1 or fullscreen, and 16:9, also known as 1.78:1 or widescreen. However, can you exactly figure out what their functions are and how to use them? Read further to get more information about such aspect ratios.
A 4:3 aspect ratio means that for every 4 inches of width in an image, you will have 3 inches of height, the screen being 33% wider than it is high. Since the 1940s, the 4:3 aspect ratio has traditionally been used in television, which is often referred to as being NTSC, or pan and scan. The majority of analog cable channels still broadcast in 4:3.
A 16:9 aspect ratio means that for every 16 inches of width in an image, you will have 9 inches of height, which is 78% wider than high. The 16:9 aspect ratio developed from the film industry, is a product of movie producers. The reasons are that they want to make their movies bigger and better and provide some different experience for viewers from what they could view on television. Most modern HDTV screens are designed for 16:9 images. Only some older TVs are built to accommodate the 4:3 aspect ratio.
A 1.85:1 aspect ratio means a width of 1.85 units and height of 1 unit. This aspect ratio is a common widescreen aspect ratio for many movies, and it is slightly wider than standard 16:9 widescreen image.
A 2.39:1 aspect ratio is also known as Panavision or CinemaScope and is a popular aspect ratio for major movie releases. The 2.39:1 aspect ratio was once 2.35:1, but changed to 2.39:1 in the 1970s, which is also rounded up to 2.40:1. Please notice that these three aspect ratios are totally the same thing.
Generally speaking, if the aspect ratio of your discs or videos do not match and fill the screen, then when you play the disc or video through such display, you will always get black bars on your screen, either at the top and bottom or left and right. Though you still can have a completely image on the screen, it may not be a good experience.
