An Aspect Ratio calculator is a tool used to calculate the aspect ratio of an image. The aspect ratio is the ratio of the width to the height of an image, expressed as two numbers separated by a colon. For example, 4:3 is the most common aspect ratio used for standard televisions, and 16:9 is the most common aspect ratio used for widescreen televisions.
The components of an aspect ratio calculator include the original width, original height and the resized width. The aspect ratio calculator will use these inputs to calculate the resized height of the image.
To calculate the aspect ratio, the formula is: resized height = (original height ÷ original width ) × resized width.For example, if the original width of an image is 600px and the original height is 400px and the resized width is 300px, then the resized height would be (400/600) × 300, which equals 200px. The aspect ratio of the image would be 300x200 or 2:3.
