In fact, 1.78 times wider: the widescreen format’s aspect ratio is 16:9, resulting in 1.78:1 (16 divided by 9 is 1.78).Ī widescreen format can be resized and formatted to fit the 4:3 format (or display with black bars) Widescreen is what we perceive as the opposite since the width of that ratio is noticeably larger than its height. We, therefore, refer to the 4:3 format also as fullscreen, though a 4:3 screen cannot display all aspect ratios filling the screen without zooming, cropping, or leaving black bars. When you record an image or motion picture and then display it on a screen with the same aspect ratio, you’ll be able to fill the entire screen without losing any information or having to crop the image.

Though mathematically the same, the 4:3 format commonly refers to computer and TV screens. The aspect ratio of 1.33:1 was that of early celluloid film cameras and projectors. The equivalent ratio is therefore 1.33:1. Imagine taking a picture with a 4:3 camera which you hold horizontally: you'll fit 1.33 times more into the frame from the left to the right edge of the frame than from the top to the bottom. In practical terms, you get 1.33 times as much width as height. When you divide the values, that is the width by the height, you get 1.33 (4 divided by 3 is 1.33). These can be inches, lines, or pixels, depending on the object with that aspect ratio. The 4:3 aspect ratio describes a width of four units and a height of three units. By definition, it refers to the relationship between the width and the height, for example, of a camera, display, or projector. The aspect ratio tells you about the proportions of an image or a screen. So let’s look at all aspects of this ratio! Definition: What is 4:3 aspect ratio? But with some modern filmmakers returning to 4:3, the format is going through a renaissance.
Far from being a relic of the past, the 4:3 aspect ratio is still a default format even though cinematography and filmmaking ratios have mostly changed to widescreen.
