In other words the display is 1.33 times as wide as it is high. Another way to represent this is to divide each number by the height, so a 4:3 monitor is also known as a 1.33:1 display (4/3=1.33, and 3/3=1). A few of the most common aspect ratios we see today are 4:3 (pronounced “4-by-3”, or “4-to-3”) and 16:9.

Every screen resolution has an aspect ratio associated with it.

Related to screen resolution, and another thing to consider when screencasting is your screen’s “aspect ratio”, which is the ratio of its width to its height. At very low resolutions, images might look “pixelated” or have jagged edges, because there are not enough pixels to provide a crisp, clear image. At lower resolutions, there are fewer pixels so the items on screen will be larger and fewer items will fit on the screen. There are more pixels there to represent the data.Īt higher resolutions, the pixels are more numerous and smaller, so as a consequence the items onscreen will also appear smaller, with more items fitting on the screen. As you can imagine, if you are looking at two screens of the same size, and one has a higher resolution than the other (1600×1200 would be a higher screen resolution than 640×480 for example), the content on the one with the higher resolution will appear sharper and clearer.
