Some older models today still use the XGA fullscreen resolution of 1024 ✕ 768 pixels, but the most widespread resolution on laptops and screens is 1920 ✕ 1080 or Full HD, which is a widescreen format. The following is a brief overview of common 4:3 screen resolutions: RESOLUTION Old computer monitors have a 4:3 resolution or screen size.

But the aspect ratio is still there in the relationship between the width and the height. The higher the resolution, the more individual pixels will make up one horizontal line and one vertical column of the image, defining the width and the height in absolute terms and often in the thousands of pixels. When we talk about digital formats, we use the term resolution to describe both absolute and relative sizes. 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. No credit card required Definition: What is 4:3 aspect ratio?
